1 XVP-3901 3G/HD/SD Up, Down & Cross Converter with Audio Processor

1.1 Introduction

The XVP-3901 is a highly integrated module designed to synchronize, convert and process 3Gbps, HD and SD
signals into 3G/HD/SD hybrid plants. The card offers a dual multi-rate 3G/HD/SD input and provides simultaneous
3G/HD and SD outputs. Each output path provides independent format, color space and aspect ratio conversion
necessary to maintain a constant signal format at each of the two outputs. With its new higher video quality using
advanced motion adaptive pixel based de-interlacing, the XVP-3901 provides outstanding results regardless of the
formats and conversions made.

A fiber input/output cartridge is offered as an option. This integrates and makes fiber connectivity easier to install and
configure. Once the cartridge is installed, the inputs or outputs are selectable through the control interface. The input
of the card allows you to select between fiber and copper inputs. The outputs offer 3G/HD path on copper and the SD
path on copper, but the fiber module allows you to select between the SD or 3G/HD outputs to be sent to each fiber
connector.

To further improve on-air presentation, the XVP-3901 offers a background keying capability which allows side panels
or letterbox black bars, introduced by aspect ratio conversion, to be filled with video or graphics from the second input.
The ARC function offers fixed presets as well as variable user configurable aspect ratios. The support of AFD (Active
Format description) SM PT E-2016, VLI (Video Line Index) RP-186 and WSS (Wide Screen Signaling) allows the card
to adjust its ARC automatically without any external intervention. It will also re-insert the proper AFD, VLI or WSS on
the output along with other HANC and VANC information. With the integration of the frame sync, incoming feed
signals can be synched to house and have the proper ARC when entering the facility. The XVP-3901 also offers a
video proc-amp with full YUV/RGB level controls and RGB gamut correction.

The XVP-3901 audio capabilities are equally advanced, with processing of up to 32 channels of audio, with automatic
delay to keep lip-sync. It provides shuffling and down-mixing, and options include dynamic processing (limiter,
compressor, and expander), and four AES inputs/outputs for additional flexibility. The new loudness measurement

option allows the measurement and logging of up to 4 audio programs with iControl Loudness Monitoring software to
analyze and report complianc e with respec t to vari ous lou dness legis lat ions aroun d the world (See iControl Loudness
Monitoring).

The XVP-3901 has 2 on-board sockets for optional modules, including Dolby-E/Digital (AC-3) decoding, upmixing
using Linear Acoustic upMAX™ technology, Dolby-E encoding and Dolby Digital (AC-3) encoding. In addition to
Miranda’s own automatic loudness control (ALC) solution for up to eight programs, the XVP-3901 offers ALC using

the AEROMAX™ technolog y by Linear Acous tic , or Level Magic™ by Jünger Audio, implemented using optional

modules.
One RS-422 port is provided for automation control of ARC/User presets and a second port for Dolby Metadata input

and output. 6 GPIs for user presets recall and input selection and 6 GPIs for their corresponding tally outputs.
The XVP-3901 generates audio/video fingerprints for both outputs (via an iControl option) to detect and measure lip-

sync errors in a broadcast facility.

frame mother board for distribution of power and for connection to the controller card, and a second connector which
plugs directly into the rear connector panel for input and output.

The rear connector panel must be installed with the card out of the frame.

• To remove an existing card from the slot, tilt up the swivel handle on the front of the card to lever the connectors

apart, then use the handle to pull the card straight out of the slot.

Figure 2.1 Densité-3 frame – rear panel installation

To install the connector panel:

1. If a card is installed in the slot whose rear panel is being changed, remove it as described above.

2. Remove the existing panel (either blank or belonging to an existing card that is being changed) by releasing the

captive screw(s) at the bottom.

3. Position the new panel and secure it in place with the captive screw(s) at the bottom.

2.2 Card Installation

Once a matching rear connector panel has been installed, install the XVP-3901 card as follows:

1. Open the front panel of the frame.

2. Slide the XVP-3901 card into the slot and push gently on the handle to seat the connectors.
The card should be inserted into the right-most slot associated with the double-slot or triple-slot rear panel.

Inserting the card into the wrong slot will not damage the card, and will be flagged by the on-card status LED
flashing red to indicate that there is no connection to the rear panel.

3. Close the front panel of the frame.

2.3 Installation of the Optical Interface (option)

Refer to Annex 3 on page 149.

2.4 Installation of the Audio Modules (option)

Refer to Annex 4 on page 151.

2.5 ABUS Connection to Companion Audio Cards

When the XVP-3901 is used in conjunction with one or
two companion audio cards (Miranda’s AAP, DAP or
UAP series), the ABUS flat cable must be installed
between the ABUS connector of the XVP-3901 and the
connectors on the audio cards. The ABUS flat cable is
supplied with the audio card.

Note that audio cards from the Densité 2RU series will
require 3RU extenders for both the card and the
associated rear panel in order to fit into the Densité
3RU frame with the XVP-3901.

Note: If only one audio car d is us ed, you m ust us e the

2.6.3 Details of rear panel connections

REF IN – Studio reference input
For external synchronization, connect a black studio reference signal to the BNC labeled REF IN.

• The loop (where available) must be terminated if not used.

GUIDE TO INSTALLATION AND OPERATION

XVP-3901 | 13

The reference input must conform to SMPTE 170M/SMPTE 318M/ITU 624-4/BUT 470-6 for standard definition
signals and SMPTE 274M / SMPTE 296M for high definition signals and is used to phase the HD/SD SDI outputs to
the studio. A reference mismatch may occur if there is a difference between the input video format’s frame rate and
the reference format’s frame rate. When a mismatch occurs, the output will freeze to the reference frame rate and
produce an input error and the card-edge St atus L ED w il l turn red to indicate the mismatch.

Note that in the case of HD signals of the same frame rate, any reference signal may be used to genlock any output
signal, regardless of scan type (progressive or interlaced). When a 720p/tri-level sync reference signal is used with an
interlaced output, the output is synchronized but there may be a delay of one field depending on when the
synchronization started.

3G/HD/SD SDI IN – Serial digital HD/SD input

Connect up to two serial digital video signals, conforming to the SMPTE 424M standard for 3G input signals, SMPTE
292M standard for HD input signals or SMPTE 259M standard for SD input signals, to the BNC labeled HD/SD SDI

IN. The XVP-3901 will automatically switch to the detected line/frame rate format.

3G/HD/SD SDI OUT – Serial digital video outputs
The XVP-3901 provides two pairs of 3G/HD/SD SDI video outputs on BNC connectors, labeled 3G/HD/SD SDI OUT
A1 & A2, and 3G/HD/SD SDI OUT B1 & B2. The SDI video signal conforms to the SMPTE 424M, SMPTE 292M or

SMPTE 259M-C standard.

AES IN / OUT – Discrete AES 3 digital audio inputs and outputs (8)

The AES inputs and outputs can be configured for 110 ohm impedance using WECO connectors, or 75 ohm
impedance using BNC connectors. The choice is made through the use of an appropriate rear connector panel.

The pinout of the D-SUB connector for both
110Ω and 75Ω rear panels is shown in this chart.

Fiber I/O – Fiber-optic inputs and outputs

Rear panels whose part number ends in –F incorporate a fiber optic interface. The interface consists of two parts:

• A socket on the rear panel into which an SFP interface module is plugged

• An SFP (Small Form-factor Pluggable) module into which the optical fibers are plugged, and which incorporates

the optical/electrical interface

The optical fibers must be terminated in an LC connector.
See Annex 3 for instructions on installing and removing the SFP interface module, and for plugging and unplugging

the LC-terminated fibers.
The current SFP modules supported are:

3 User Interface

3.1 Control options

The XVP-3901 can be controlled in three diff er ent wa ys :

• The local control panel and its push-buttons can be used to move through a menu of parameters and to adjust
parameter values (see section 4).

• Miranda’s iControl system can be used to access the card’s operating parameters from a remote computer, using
a convenient graphical user interface (GUI) (see section 5).

• Miranda’s RCP-200 panel.

3.2 Card-Edge Status LED

The status monitor LED is located on the front card-edge of the XVP-3901, and is visible through the front access door
of the DENSITÉ frame. This multi-color LED indicates the status of the XVP-3901 by color, and by flashing/steady
illumination.

The chart shows how the various error conditions that can be flagged on the XVP-3901 affect the LED status.

• If a cell is gray, the error condition cannot cause the LED to assume that status

• If more than one LED status is possible for a particular error condition, the status is configurable.

See Section 5.20 for details.

• The factory default status is shown by a 

The LED will always show the most severe detected error status that it is configured to display, and in the chart error
severity increases from left to right, with green representing no error/disabled, and flashing red the most severe error.

4 Local control using the Densit é fra me control panel

4.1 Overview

Push the SELECT button on the XVP-3901 card edge
(see Section 1.4) to assign the local control panel to
operate the XVP-3901. Use the control panel buttons to
navigate through the menu, as described below.

All of the cards installed in a Densité frame are
connected to the frame’s controller card, which handles
all interaction between the cards and the outside wor ld .
There are no operating controls located on the cards
themselves. The controller supports remote operation
via its Ethernet ports, and local operation using its
integrated control panel.

The local control panel is fastened to the front of the
CPU-ETH2 controller card, and when installed is located
in the front center of the frame, positioned in front of the power supplies. The panel consists of a display unit capable
of displaying two lines of text, each 16 characters in length, and five pushbuttons.

The panel is assigned to operate any card in the frame by pushing the SELECT button on the front edge of that card.

• Pushing the CONTROLLER button on the control panel selects the Controller card itself.

• The STATUS LED on the selected card flashes yellow.

The local control panel displays a menu that can be navigated using the four pushbuttons located beside the displ a y.
The functionality of the pushbuttons is as follows:

[+] [–] Used for menu navigation and value modification
[SELECT] Gives access to the next menu level. When a parameter value is shown, pushing this button once

enables modification of the value using the [+] and [–] buttons; a second push confirms the new value

[ESC] Cancels the effect of parameter value changes that have not been confirmed; pushing [ESC] causes the

parameter to revert to its former value.

Pushing [ESC] moves the user back up to the previous menu level. At the main menu, [ESC] does not

exit the menu system. To exit, re-push the [SELECT] button for the card being controlled.

If no controls are operated for 30 seconds, the controller reverts to its normal standby status, and the selected card’s
STATUS LED reverts to its normal operating mode.

4.2 Menu for local control

The XVP-3901 has operating parameters which may be adjusted locally at the controller card interface.

• Press the SELECT button on the XVP-3901 front card edge to assign the Densité frame’s local control panel
to the XVP-3901

• Use the keys on the local control panel to step through the displayed menu to configure and adjust the XVP-

3901.

The complete menu structure is shown in Annex 1 to this document, beginning on page 141.

This panel allows input selection, second input operation
mode selection, and control of the deglitcher and freeze
functions.

Input Select: choose one of the two inputs connected to the
rear panel.

• Input 1&2 assignments are done in the Input/Output
Config Tab below.

• Note that the XVP will switch the inputs on the switch
line only when using this control and not while using
the Input Config controls.

• The video input status in the top section (icon #2 and
#3) refers only to the in puts selected here.

GUIDE TO INSTALLATION AND OPERATION

XVP-3901 | 23

5.2.1 Input/Output Config Tab

Input Config: use the pulldowns to select the rear panel
input that will be used when the inputs are selected:

• BNC IN – use one of the electrical inputs

• Fiber IN – use one of the fiber optic inputs (1, 2 or

both will be listed)

• The pulldowns are greyed and non-functional if the

installed rear panel does not incorporate a fiber SFP
socket

• If the Fiber Input name is red in the pulldown, it

indicates that an appropriate fiber module has not
been detected in the SFP socket

BNC Output Config: Use the pulldowns to select whether
the named output will be HD or SD.

Fiber Output Config: Use the pulldowns to turn the fiber transmitters for each output ON (either HD OUT or SD OUT)
or OFF

• This section of the panel only appears when a rear module with a fiber SFP socket is installed

• If the selection is invalid (e.g. no appropriate transmitter installed in the SFP socket) then the select ion will be

red in the pulldown and a warning message will appear if it is selected

• Information about the installed SFP module can be found in the SFP Info tab, which only appears when a rear

module with a fiber SFP socket is installed

5.2.2 Input 2 tab

Input 2 Mode: Specify the operation mode for the second
input using the pulldown. Available choices are:

 2x1 Switch: when this mode is selected, the card can be

manually switched between the 2 inputs, using the radio
buttons in the Input Se lect area. Keep in mind that all
current settings (ARC, audio, etc.) will remain and be
applied to input 2.

 Fail Over: when this mode is selected, the card will

automatically switch from input 1 to input 2 when input 1
is lost for a delay longer than the Auto Sw i tc h Delay set
below.

• All current settings (ARC, audio, etc.) will remain and
be applied to input 2.

• The card will remain on input 2, even if input 1 returns to normal, until it is manually reset to input 1

Auto Switch Delay (sec): using the slider, set the Auto Switch Delay, from 0 to 15 seconds in steps of 1 second.
Some points to note for the Failover mode:

• The Failover mode only switches from input 1 to input 2, not from 2 to 1.

Figu

re 5.3 Video Input/Output – I/O Config tab

Video Input/Output – Input 2 tab

GUIDE TO INSTALLATION AND OPERATION

24 | XVP-3901

• If input 2 and Failover mode are both selected, an error is reported by iControl and the card edge LED turns
red. The second input is always required in this mode.

• Both input signals must be present – the system cannot switch to input 2 if there is no signal there – and the
absence of either of the signals will be flagged as an error (icon #2 and card-edge LED red)

• If there is no input 2, the iControl carrier detect icon for input 2 will be red, but no input error will be flagged.

 Key / Fill: when this mode is selected, the card uses input 1 as the main video input, and the second input is

used as background graphics to the output side panels or letterbox. For this mode to function properly:

• The second input must be the same format as the output.

• In order for the two signals to be properly phased at the keyer, it is necessary for the second input to be

timed between 414 pixels and 1 line+413 pixels ahead of the output timing.

• If the second input is lost, the specified background color is used until the input comes back.

• Input 2 selection in the Input Select area is disabled in the Key/Fill mode.

The format and status for the second input is displayed in an icon at the top of the interface.
Key/Fill Output: Use the pu lld o wn to select wh eth er the Ke y/F ill outpu t will be SD or HD.

5.2.3 Deglitcher tab

When the Deglitcher is active, the card supports a hot-switch
between two signals (either on the same input, or between
the card’s two inputs) without producing a freeze on the frame
sync, and without producing artifacts on the output.

The deglitcher must be disabled when the input is
asynchronous to the reference. Otherwise, it will create
audio and video glitches at the output.

Mode: select OFF or ON from the pulldown.

• Note that the Deglitcher cannot be enable d for
1080p23, 1080p23sF, 1080p25 and 1080p29 sources

For this mode to function correctly, the following requirements
must be met:

• The two inputs must be synchronized to the reference

• They must be phased within one line of each other

• They must be phased to within +/- ½ line of the HREF of the reference signal

The offset from the VREF can be variable, but a distance of greater than 10 lines could create an artifact in the active
video. If the two signals are more than 1 line apart, we will see a vertical jump at the moment of switching that is
proportional to the number of vertical lines of offset between the two signals. This will last for only one frame. There
may also be problems in the transition when in the AFD automatic or forced mode.

When a reference is present and the deglitcher is active, the card reports the difference in timing between the input
and the reference when the transition occurs.

• If the reference is missing when the deglitcher is activated, the Input timing to reference box will indicate
“Missing reference” in red, and the reference status icon at the top of the iControl window will turn red and show
the message “Reference missing”.

• If the deglitcher is OFF, the reference status icon will be grey, and its message will read “Reference absent”

reference is not important for the deglitcher to operate properly.

You may switch between signals A, B or C, without any glitch, and also between signals DE and signals FG. Any
other transition, like AD, will cause a vertical image shift for one frame.

To determine whether a clean hot switch is possible, you need to determine whether the two input signals lie in the
same clean switch region. There are two ways to measure the position of the signals with respect to the reference:

• Use the deglitcher tab in iControl (InputDeglitcher)

• Use the controller menu in Appendix 2 (videotimingin timing to ref).

When the deglitcher mode is on, each of these sources will display the alignment offset between the reference signal
and the input signal. Knowing the offset for both input signals, you can determine if they are in the same clean switch
region. If so, any hot-switch between those two signals will be glitch less.

To determine the limits of a clean switch region, you must know the input’s line length in µs. The first region is
delimited by +½ line and -½ line of the reference. For exam ple, with an SD (525) signal the line length is 63.5 µs and
so the first region lies between -31.76 µs and 31.76 µs. Other regions can be found by adding or removing a multiple
of line length to the two boundaries.

Example: for an SD (525) input signal, we have these clean switch regions:

-1 line and -31.76 µs to 0 line and -31.76 µs
0 line and -31.76 µs to 0 line and 31.76 µs
0 line and 31.76 µs to 1 line and 31.76 µs
etc.

Practical examples:

Example 1: we have two SD (525) sources, one that indicates an offset of -25 µs with respect to the reference (A)
and the other an offset of -35 µs (B). We know that a clean switch region limit is present at -½ line, w hic h corresponds
to -31.76 µs. We can now determine that this switch will not be clean, because the two sources are on opposite sides

of the limit, and are therefore not in the same clean switch region.

line plus one line. These correspond to 31.76µs and 95.28µs. We can now determine that this switch will be clean,
because the two sources are inside the same clean switch region.

5.2.4 Freeze tab

Freeze type: This is a pull-down menu with four options –
FIELD 1, FIELD 2, FRAME and BLACK. It determ ines the
manner in which the XVP-3901 responds to a manual freeze,
a video input switch (“hotswitch” as defined by SMPTE
recommended practice RP-168, revised January 2002), a
loss of input signal or other input errors. The four possible
options yield the following results:

Auto Freeze: This pulldown (ON/OFF) enables or disables the auto freeze function. In Auto Freeze mode, a
reference must be present to ensure a glitchless output when a freeze is activated. There are only two freeze
possibilities in Auto mode: free ze to last vali d Field or freeze to black. When Auto Freeze mode is disabled, the
content of the active picture will reflect whatever garbage is present at the input but, if a reference is present, the
output synchronization will be maintained to avoid unlocking downstream equipment.

Manual: Select this checkbox to immediately freeze the output according to the mode selected in the Freeze Type
pull-down.

Note: The manual freeze setting is saved in the non-volatile memory of the card. If the manual freeze is activated and
the power is cycled, the card will start in freeze mode at the next power-up and the output will be invalid. Just turn off
the manual freeze to restore the output.

In all cases, audio will be muted when there is an input error. See the audio section for more information.

5.2.5 SFP Info tab

This tab only appears when a rear panel with a fiber SFP
socket is installed. These panels are identified by the suffix
–F in the panel name.

The data boxes in this tab identify the vendor name and part
number, and the optical power – incoming for a receiver (RX)
or outgoing for a transmitter (TX).

5.3 Video Processing panel

This panel contains color-correction parameters that apply to
the input signal. You can configure the video processor
differently for an SD input than for a 3G/HD input. The card
will remember the different parameters and will load them
automatically without user i nterv ent ion bas e d on whet her the
video input is SD or 3G/HD. Ensure the card has a video
signal of the desired format before changing the
configuration.

Proc Mode: Select whether the processing controls will be
presented in YCbCr or RGB format.

• It is important to understand that gain/offset values from
the current Proc Mode will be applied to the newly
selected mode. This may cause adverse effect. To avoid
it, return the gain/offset values to their default values
(zero).

RGB Gamut: When ON, all illegal YCbCr colors in the RGB
space will be clipped to a legal value.

5.3.1 Basic tab

All Gain: Sets Luma and Chroma gains, or G, B and R gains to a specific value. When other gains are individually set,
ALL GAIN reflects the average value of the combined gains.

The choice of processing mode made at the top of the panel determines what other controls are provided. The table
below lists the sliders and the available control ranges.

• For gain control, a nominal value of 0 represents 100% gain, while -800 represents 0% gain, and +800
represents 200% gain.

5.3.2 Advanced tab

This tab provides individual controls for each of these parameters.

5.4 Vide o O utputs panel – 3G/HD Output tab

This panel allows control over several aspects of the video
output:

• aspect ratio conversion

• timing control

• image quality processing

• metadata insertion.

The upper portion of the panel is occupied by two video
screen images, labelled Input and Output. These screens do
not show the actual video being processed by the XVP­3901, but rather show graphic images that represent the
geometric aspects of the input signal and the output that
results after it is exposed to the current ARC processing
functions. The image is a green circle on a white
background; the circle is used because it is easy to see if it
is asymmetrical. Lines on the images indicate protected
areas for the AFD implementation.

Aspect Ratio Conversion (ARC) modifies the video active
picture shape as the signal is converted between SD at 4:3
aspect ratio and HD/SD at 16:9 aspect ratio. If the input is
simply stretched or squeezed to fit the output, the image will
be asymmetrically distorted; this is called anamorphic
distortion. If the image is expanded or contracted
symmetrically, it must be cropped, and/or have new blank
background segments added to it, in order to fill the output picture. The ARC processing in the XVP-3901 allows a
wide range of symmetrical and asymmetrical picture size modification, coupled with cropping and background
addition, to be applied to an input signal.

When the Input AFD Mode is set to Auto, all the ARC settings are set automatically according to the AFD flag (see the
table in Annex 2 beginning on page 145) and cannot be changed by the user.

• There are some exceptions – with certain input AFD codes the masks can be customized. Each mask can be
customized for each different AFD code allowing different mask settings according to each specific code. For
certain AFD codes that are less used, the masks cannot be configured and will be de-activated.

The Input Screen

The Input preview screen shows the portion of the input image which will be presented at the XVP-3901 output. It has
a pull-down AFD Mode menu at the top right corner through which the user specifies how AFD (Active Format
Descriptor) information will be handled. Available choices are: [4:3, 16:9, Auto, Forced] for SD inputs and [16:9, Auto,
Forced] for HD inputs.

You can configure the AFD mode differently for an SD input than for a 3G/HD input. The card will remember the
different parameters and will load them automatically without user intervention based whether the video input is SD or
3G/HD. Ensure the card has a video signal of the desired format before changing the AFD mode configuration.

Note 1 – Auto mode: When Auto is selected, all the ARC values are automatically set based on the AFD flag
detected at the input, and the ARC controls and presets described below are disabled. Annex 2 shows the AFD
functions implemented. If no AFD flag is detected at the input, the card uses the Default AFD flag specified in the
AFD tab

Note 2 – Forced mode: Forced mode is useful when the input AFD flag is unreliable, missing or if the user wants a
simple way to force the aspect ratio conversion. The function is the same as the Auto mode, except that the
incoming AFD flag is ignored, and a user-specified forced flag is used instead. As in the Auto mode, the ARC
controls and presets described below are disabled.

Note 3 – 4:3 or 16:9: ARC settings can be manually set using the ARC tab controls.

The input screen shows how much of the input signal will appear at the output after the ARC processing in the XVP-

3901. It does so by showing any cropped portions of the image in blue.

The Output Screen

The output screen shows the final result of the ARC processing.

• The side panels and letterbox regions are shown in the selected background color

• The masks are shown in Gray

3G/HD output – A pull-down menu at the bottom of the screen allows the user to select the output format:

• 1920x1080p – Level A (mapping 1), 1920x1080p – Level B, 1920x1080i or 1280x720p, with the frame rate
matching the input.

XVP-3901 | 31

5.4.1 3G/HD Output – ARC tab

Under the ARC (Aspect Ratio Conversion) tab, several sub­sections are found allowing extended control over how the
output will be displayed. For convenience, ARC presets are
available for frequently-encountered aspect ratio
conversions.

• These controls are disabled when the ARC Mode
pulldown on the Input Screen is set to Auto or Forced

You can configure the ARC parameters differently for an SD
input than for a 3G/HD input. The card will remember the
different parameters and will load them automatically without
user intervention based on whether the video input is SD or
3G/HD. Ensure the card has a video signal of the desired
format before changing the configuration.

When using manual aspect ratio mode (AFD mode is 4:3 or
16:9), the card will remember automatically all the
parameters for the different combinations of input/output
aspect ratio conversions (see the combinations below). This means you can configure the card once for each type of
conversion and then the card will restore the configuration automatically when the proper input format and
input/output aspect ratio is encountered.

• SD 4:3 to 3G/HD 16:9

• SD 16:9 to 3G/HD 16:9

• 3G/HD 16:9 to 3G/HD 16:9

5.4.1.1 Input sub-section

Input: Crop – Horizontal and Vertical

The crop controls allow selection of a portion of the original image – the amount of horizontal and vertical cropping is
expressed as a percentage of the size of the original image.

The user can manually adjust the level of horizontal and vertical cropping. Horizontal cropping is done on an 8-pixel
basis. Vertical cropping is done on 4-line basis. To achieve non-symmetrical vertical or horizontal cropping, uncheck
the Center box underneath and position the image using the Tilt function described below.

Input cropping changes the scaling factor between the input and the output. If we crop the input (H&V) by 10%, the
output image is resized and scaled by +10%. By providing different H and V cropping, the user can produce an
anamorphic image.

The padlock icon appearing next to the data window allows the data to be “locked”. See the paragraph Locking

controls under Output sub-section below for a discussion of this option.
Input: Tilt

Once a smaller window has been established by cropping the input signal, it can be moved vertically (Tilt, expressed
in lines) within the original image to place the desired portion of the image in view. By default, a Center check box
beneath the Tilt scroll box forces the cropping window to be centered on the input window. When it is checked, the
necessary Tilt value will be calculated and displayed in the Tilt data window. You cannot tilt if the cropping value is
zero.

Figure 5.12

Video Output 3G/HD - ARC tab

GUIDE TO INSTALLATION AND OPERATION

32 | XVP-3901

Input: Pan

Once this smaller window is established, it can be moved horizontally (Pan, expressed in pixels) within the original
image to place the desired portion of the image in view. A Center check box beneath the Pan scroll box forces the
cropping window to be centered on the input window. When checked, the necessary Pan value will be calculated and
displayed in the data window. You cannot Pan if the cropping value is zero.

5.4.1.2 Output sub-section

Output: Side Panels

This scrollable data entry box is used to shrink the width of the image so that the output image has blanked areas on
each side of the displayed picture, which occupy the indicated percentage of the screen width. These areas are
symmetric about the center, so a setting of 25% side panels would show a bar 12.5% of the screen width on each
side of the image. 25% is the maximum value; entering a smaller value reduces the width of the side panels, but crops
the image top and bottom. This control is disabled when the input is 16:9.

Output: Anamorphism

This control box allows the output image to be resized asymmetrically. Anamorphism is expressed in percent, where
positive values indicate an increase in width with respect to height, and negative values a decrease in width with
respect to height.

Output: Position

This pulldown allows the positioning of the output picture when side panels are in use. The picture can be moved
totally to the left, centered or totally to the right. This control is not available in Auto AFD mode or Forced AFD mode.
The picture will be centered by default when an ARC Preset is selected.

Locking controls
Represented by padlock icons, these buttons allow the V Crop, H Crop, S ide Pa nels and Anamorphism controls to be
“locked”. When a control is locked, user access to that control is disabled. Changes to unlocked controls will not affect
the data values of locked controls. There is some interactivity within the locking function, as follows:

• If either V Crop or H Crop is locked, Anamorphism is unlocked.

• If either Side Panels or Anamorphism is locked, the other is unlocked, along with V Crop and H Crop.

5.4.1.3 Presets sub-section

For convenience in manual operation, several of the most common conversion situations are pre-programmed into the
XVP-3901, and can be quickly accessed. The available Presets change according to the AFD mode and Output
Format selections made using the pulldowns on the input and output screens.

The chart in Figure 5.13 illustrates graphically the effect of each preset on the input image.

• Only those presets for which an output is shown will appear on the Video Output panel.

• For example, when the input and output formats are the same, only the Bypass button will appear

• In all cases, a button labeled Custom will appear, and will be selected whenever the parameter settings do not

correspond exactly to one of the available presets

The advantage of using Presets is to provide a unique conversion without having to specify the H&V scaling factor or
the percentage of cropping/side panels and anamorphism. When an ARC Preset is selected, it re-centers the output
picture in case of side panels or letterbox, but it does not affect the output masks.

XVP-3901 | 33

5.4.1.4 Masks sub-section

Mask: Horizontal and Vertical
Sometimes with aspect ratio conversion, some of the edges of the original image are exposed in the output signal.
Often, there will be artifacts in the source along these edges, extending for several lines vertically or several pixels
horizontally after conversions. Masks are adjustable “curtains” which can be used to frame the output image, covering
up the edge artifacts and leaving a clean transition from image to mask.

Four scroll boxes with data windows for reporting and direct data entry are used to set the mask position on the four
sides of the output image. Top and bottom position are set in lines, while left and right position are set in pixels.

Masks should be adjusted by viewing the output on a video monitor and positioning the masks to cover edge effects
with a minimum loss of clean picture content. Usually masks are the final adjustment to be made. The masking is
shown on the top right Output screen by graying out the masked portion. Note that mask – or Background - color may
be changed in the Advanced tab. The maximum amount of masking that can be introduced depends on the image

5.4.2 3G/HD Output – Ti m ing tab

The Timing tab provides access to timing adjustments which
affect the signal outputs. There are two slider controls, each
with a data reporting box which shows the current value, and
into which values can be typed directly. The total delay is
reported at the top of the window.

Vertical HD (lines): With this adjustment, a value ranging
from –16 to +15 lines compared to the reference or the
processing delay, may be set. This adjustment can be used
in conjunction with the horizontal timing adjustment.

Horizontal HD (µs): With this adjustment, a value ranging
from zero to the equivalent of 1 horizontal line in the current
output format compared to the reference or the frame
boundary may be set.

Additional Frame Delay: This parameter affects the overall processing delay of the card. It adds supplemental frame
delay to the current processing delay. This parameter will add a delay ranging from 0 to 15 interlaced frames (steps of
33 ms in 59.94 Hz and 40 ms in 50 Hz) to the current processing delay. Without a reference, the normal processing
delay is 1 frame. You can extend this delay up to16 frames if the additional delay is 15. With a reference, up to 15
frames can be added to the frame sync delay which depends on the timings between the input and the reference.

Note that, in order to compensate for the processing delay of a Dolby-E/Dolby Digital decoder or a Dolby-E encoder
installed on the XVP-3901 or on the companion audio card, the additional frame delay must be set to at least one (1)
frame. On the other hand, if a Dolby Digital encoder is installed, the additional frame delay must be set to at least six
(6) frames for 59.94 Hz formats and at least five (5) frames for 50 Hz formats.

5.4.3 3G/HD Output – Advanced tab

The Advanced tab provides controls over the type and level of
detail enhancement that will be performed, and the color of
the mask. The panel differs between 3G/HD output and SD
output

5.4.3.1 Image Processing section

MPEG Preprocessor Mode: This control changes the
functionality of the detail enhancer.

• When MPEG preprocessor is activated (‘ON’), the
adaptive detail enhancer will use a ps ycho-visual model
to increase the level of details and the sharpness of
edges without adding high frequency content that may
be difficult to encode at a lower bit rate on a
downstream MPEG encoder.

Figure 5.14 Video Output 3G/HD - Timing

GUIDE TO INSTALLATION AND OPERATION

XVP-3901 | 35

• When the MPEG preprocessor is deactivated (OFF), the adaptive detail enhancer will increase the details and

the sharpness of edges without causing ringing on the HD output. In this mode (‘OFF’), high frequency content
is added to the HD video output to improve graphic contents and characters. This setting is very useful for
upconverted material in character generation (CG) applications.

Detail Enhancer: Enhances the perceived sharpness of fine detail and edges. A single control adjusts both Horizontal
and Vertical detail enhancement: a slider and a data reporting/entry box allow the user to select a value ranging from
0 (no enhancement) to 7 (maximum enhancement). The default value varies according to the processing mode: 4 for
SD to HD mode and 0 for HD to HD mode.

5.4.3.2 Background Color section

The color patch (black by default) indicates the color that will be used for the masks, and will therefore surround the
output image when it does not occupy the full output screen. Click on the Change… button to open the Background
Colors window. This windo w incl udes YCbCr sliders with data entry boxes, and a color preview patch. The color is
represented by an 8-bit value for each component.

• If you have selected an illegal RGB color, it will be
flagged as “Invalid RGB” beneath the color patch, and
also within the color patch shown in the Advanced tab if
you apply it. This invalid RGB color will not be clipped by
the Gamut correction. Make sure you select a valid RGB
color if you care about Gamut errors.

• Colors for HD and SD masks are specified independently
when the corresponding output format is selected. The
same color is used in 720p and 1080i.

5.4.4 3G/HD Output – Meta tab

The Meta tab provides resources to deal with Metadata incorporated into the incoming signal.

5.4.4.1 Meta / Meta sub-tab

Closed Caption section

Presence: this icon turns green in the presence of valid incoming EIA-708-B or EIA-608-B closed captioning data as
per SMPTE-334M when an HD source is installed or when line 21 closed captions are detected when an SD source is
installed.

Insertion: The pull-down is used to select between Auto or
OFF. Availability of these controls is affected by whether or

not Line 21 of the input SD or output SD signal has been
configured as blanking; see SD Input/Output Config
subsection below for details.

When Auto is selected, closed captioning information is
processed as follows:

• SD to 3G/HD Upconversion:
The closed-captioning information from line 21 field 1
and the V-chip information from line 21 field 2 of the
incoming 525-line signal may be inserted as ancillary
packets required for FCC compliance. NTSC and DTV

• Audio, closed-capti oning, time-code, and AFD data is not handled by this parameter. The only exception is

time code during HD-to-HD operation, in which case the user must enable this parameter along with the time
code insertion pulldown menu, in order to properly process time code insertion.

• HD to HD (same format): All incoming HANC packets within H blanking and VANC packets within VBI may be
bypassed to the output.

• HD to HD (different format) cross-conversions also supported.

• HD to HD blanking conversions are applied on luminance channel only. Packets in chrominance channel not

supported.

• VBI insertion is disabled for 1080p23/1080p23sF/1080p25/1080p29 input HD formats

• 3G to 3G conversions: same as for HD to HD conversions

5.4.4.2 Meta / Namedropper sub-tab

Namedropper is a method of inserting control information for
down-stream graphics inserters. It is a waveform-shape
located on line 18 in SD, but a VANC packet on line 11 in HD.
The XVP-3901 detects the presence of Namedropper data in
the program arriving at its input, and flags it using the status
icon in this panel, which turns green when Namedropper
data is detected.

5.4.4.3 Meta / Timecode sub-tab

SD inputs: In the case of an SD input, the DVITC in the VBI

interval is transcoded into ATC time code packets for the
3G/HD output.

Two types of ATC packets may be produced in 3G/HD:

• VITC

• LTC.

VITC type time code is handled by Timecode 1 parameters
whereas Timecode 2 parameters handle LTC type time code
insertion in 3G/HD. It is not possible to automatically detect 2
different lines of timecode. In order to have the possibility to enable and produce LTC type time code make sure to set
the SD Detection Line in Timecode 1 to a specific line number. Doing so will unlock the Timecode 2 parameters.

HD inputs: all incoming ATC packets (including type LTC) are bypassed to the HD output. Make sure to enable both

timecode and VBI (in Meta tab) parameters.

The XVP-3901 does not pass LTC type timecode detected within input HD formats 1080p23 / 1080p23sF / 1080p25 /
1080p29. It is not necessary to enable VBI to pass incoming VITC type time code for the aforementioned formats.

Timecode binary group data is guaranteed to be transparent from input to output, except for
1080p23/1080p23sF/1080p25/1080p29 input formats.

Presence: A presence icon is available for each type of incoming ATC packet. The Timecode 1 Presence icon turns
green when VITC type timecode is detected and the Timecode 2 Presence icon turns green when LTC type timecode
is detected. If the input is SD, then the presence of each icon depends on the selection of the SD Detection Line
parameter.

SD Detection Line: Select AUTO mode to automatically detect the line that contains the timecode. If time code
appears on multiple lines, the first is selected. Select a specific line if desired; this allows a choice to be made when
multiple time code lines are present. There is no AUTO selection available for Timecode 2.

Insertion: Insertion options are available through a pull-down menu, offering these choices:

AUTO: Time code is inserted if present; insertion is disabled if no time code is present.
OFF: Time code insertion at the output is disabled.

5.4.4.5 Meta / Teletext sub-tab

In 50 Hz operation only, incoming teletext on SD signals
can be converted to OP-47 and inserted in the HD output.
This panel configures this functionality.

SD inputs – incoming SD Teletext waveforms conforming to
the ETSI EN 300 706 standard are converted to OP-47
packets and inserted in the outgoing HD signal.

• The Incoming Teletext Presence indicators 7 to 22

indicate the SD lines where teletext data, conf or ming
to ETSI EN 300 706, has been detected.

• Use the checkboxes in the Teletext to OP-47 Selection

area to choose the lines whose teletext information will
be converted to OP-47 and inserted in the HD output.

The insertion mode pulldown offers two modes of operation:

• OFF – no teletext packets will be inserted as OP-47 at

the output

• AUTO – the incoming teletext from the lines selected in the Teletext to OP-47 Selection checkboxes above the

pulldown will be converted to OP-47 packets, and inserted in the outgoing HD signal, in the line selected in the
Insertion Line pulldown.

HD Inputs – incoming teletext (OP-47) is passed through to the output as received (PASS mode).

• The presence indicators 7 to 22 represent SD line number data detected in any incoming OP-47 packet. For

example, if presence indicators 8 and 10 are turned on, this indicates detected OP-47 data is carrying teletext
data derived from (or targeted for) SD lines 8 and 10.

5.4.5 3G/HD Output – AFD tab

The Active Format Descriptor (AFD) flag is used to identify the aspect ratio and protected areas of a video signal. The
XVP-3901 uses this flag in some cases to adjust the output aspect ratio and image cropping to obtain the best
possible presentation of the image. The AFD flag is implemented differently in SD and HD:

• In HD, the AFD flag (SMPTE 2016) is sent in an ancillary packet, normally found on line 11 in the vertical ancillary
space.

• In SD, the AFD flag may be sent as a VLI signal (RP 186), as a WSS signal (ITU-R BT.1119-2) for PAL only, and as
an AFD packet (SMPTE 2016).

When an AFD flag is present at the input, the card can perform an automatic adjustment of the aspect ratio. See the
appendix for more details.

5.4.5.1 Default settings section

Default/Forced: this text box is labeled according to the mode selected in the Input Screen pulldown in the Video
Output Group – see page 30

• In AUTO mode, labeled DEFAULT and shows the current default AFD code to be used if no valid AFD code is

detected at the input.

• In FORCED mode, labeled FORCED, and shows the

code that is forced into the system input regardless of the
actual input code.

• In 4:3 (SD input) or 16:9 mode, t he dat a box is em pt y and

the controls are grey. In this mode, ARC settings can be
manually set using the ARC tab controls.

Change: Click the Change button to open the Select AFD
panel showing the available AFD codes that could be used as
the default. Click on one to select it, then click Apply or OK at
the bottom of the panel.

Keep Last: click in this checkbox to use the last detected
AFD code at the input as the default code to be used in the
Auto mode when no AFD flag is detected. This box is
disabled in the Forced mode.

5.4.5.2 Config section

Incoming – the three types of AFD are shown, with a presence icon for each, and a pulldown to establish the priority

of each type. The priorities are reset with each new selection; e.g. if AFD is 1 and VLI is 2, and you use the pulldown
to choose VLI priority as 1, then AFD will be bumped down to 2.

• Ignore a specific flag completely by selecting “Don’t use” as its priority level.

The available types depend on the input format – AFD only for HD inputs; AFD and VLI for SD-59.94 Hz inputs, and
all three types for SD-50 Hz inputs.

Figure 5.22

Video Output 3G/HD – AFD tab

GUIDE TO INSTALLATION AND OPERATION

XVP-3901 | 41

The set priority is used only during AUTO mode. The XVP-3901 will examine the incoming data in the selected order
of priority in order to extract the AFD data. If, in AUTO mode, an AFD flag is set to priority 1 and is missing at the
input, the XVP-3901 will use the incoming AFD flag set to the next priority level.

The Detected box shows the AFD code detected.

Outgoing – on the HD output, the AFD code shown in the Inserted box will be inserted in the line selected in the
Insertion Line pulldown, as an Ancillary Aspect Ratio packet (SMPTE 2016). Deselect the AFD checkbox to inhibit

insertion. Note that VLI and WSS flags cannot be inserted on HD-SDI signals.
Field Extract AFD & VLI – Select the field from which AFD and VLI will be extracted:

• Field 1

• Field 2

• Field 1 & 2

Note that this selection applies to both HD and SD outputs, and can also be set from the equivalent panel in the SD
Output section (see page 57).

5.4.6 3G/HD Output – De-interlacer tab

Some interlaced video sources are film-based originating
from 24p film images. For optimum scaling performance, it
would be best to de-interlace this type of source by simply
merging the source’s fields to recreate the original 24p image,
thereby introducing no de-interlacing artifacts prior to scaling
and format conversion.

Film mode: When The Film Mode selection is set to ON, the
XVP-3901 monitors the input for film-based sequences and
applies the proper algorithm.

Film detection is provided for 3:2, 2:2 (59Hz and 50 Hz sources) and 5:5 sequences.
Video Over Film: When the film mode is enabled, turn ON the Video-Over-Film (VOF) function to detect and bypass

field-merging on certain video regions such as scrolling video characters over an entire film frame, thereby preventing
any unwanted combing eff ects.

There is only one de-interlacer on the card. Any changes made within this tab will be copied over to the De-interlacer
tab in the Video Output (SD) panel.

5.5 Vide o O utputs panel – SD Output tab

This panel allows control over several aspects of the standard definition video output:

• aspect ratio conversion

• timing control

• image quality processing

• metadata insertion.

Figure 5.

23 Video Output 3G/HD - De-Interlacer tab

GUIDE TO INSTALLATION AND OPERATION

42 | XVP-3901

The upper portion of the panel is occupied by two video
screen images, labelled Input and Output. These screens do
not show the actual video being processed by the XVP-3901,
but rather show graphic images that represent the geometric
aspects of the input signal and the output that results after it
is exposed to the current ARC processing functions. The
image is a green circle on a white background; the circle is
used because it is easy to see if it is asymmetrical. Lines on
the images indicate protected areas for the AFD
implementation.

Aspect Ratio Conversion (ARC) modifies the video active
picture shape as the signal is converted between SD at 4:3
aspect ratio and HD/SD at 16:9 aspect ratio. If the input is
simply stretched or squeezed to fit the output, the imag e will
be asymmetrically distorted; this is called anamorphic
distortion. If the image is expanded or contracted
symmetrically, it must be cropped, and/or have new blank
background segments added to it, in order to fill the output
picture. The ARC processing in the XVP-3901 allows a wide
range of symmetrical and asymmetrical picture size
modification, coupled with cropping and background addition,
to be applied to an input signal.

When the Input AFD Mode is set to Auto, all the ARC
settings are set automatically according to the AFD flag (see
the table in Annex 2 beginning on page 145) and cannot be
changed by the user.

• There are some exceptions – with certain input AFD codes the masks can be customized. Each mask can be
customized for each different AFD code allowing different mask settings according to each specific code. For
certain AFD codes that are less used, the masks cannot be configured and will be de-activated.

The Input Screen

The Input preview screen shows the portion of the input image which will be presented at the XVP-3901 output. It has
a pull-down AFD Mode menu at the top left corner through which the user selects the aspect ratio of the input signal.
Available choices are: [4:3, 16:9, Auto, Forced] for SD inputs and [16:9, Auto, Forced] for HD inputs.

Figure 5.25 Screens for SD output

You can configure the AFD mode differently for an SD input than for a 3G/HD input. The card will remember the
different parameters and will load th em automatically without user interve nti on based on whether the video input is SD
or 3G/HD. Ensure the card has a video signal of the desired format before changing the AFD mode configuration.

Note 1 – Auto mode: When Auto is selected, all the ARC values are automatically set based on the AFD flag
detected at the input, and the ARC controls and presets described below are disabled. Annex 2 shows the AFD

Video Outputs – SD Output

GUIDE TO INSTALLATION AND OPERATION

XVP-3901 | 43

functions implemented. If no AFD flag is detected at the input, the card uses the Default AFD flag specified in the
AFD tab

Note 2 – Forced mode: Forced mode is useful when the input AFD flag is unreliable, missing or if the user wants a
simple way to force the aspect ratio conversion. The function is the same as the Auto mode, except that the
incoming AFD flag is ignored, and a user-specified forced flag is used instead. As in the Auto mode, the ARC
controls and presets described below are disabled.

Note 3 – 4:3 or 16:9: ARC settings can be manually set using the ARC tab controls.

The input screen shows how much of the input signal will appear at the output after the ARC processing in the XVP-

3901. It does so by showing any cropped portions of the image in blue.

The Output Screen

The output screen shows the final result of the ARC processing.

• The letterbox and side panel regions are shown in the selected background color

• The masks are shown in Gray

A pull-down menu at the top of the screen allows the user to select the output aspect ratio:

• Either 4:3, 16:9, or AUTO.

• AUTO output setting allows the XVP-3901 to automatically select between a 4:3 or 16:9 output aspect ratio. This

decision is based on factors including the input AFD flag during input AUTO or FORCED modes, and the ARC
settings during manual modes. The aim of this output AUTO mode is to reduce the amount of side panel or
letterbox regions. Refer to the AFD table at the end of this document in order to understand visually this mode of
operation

 Note – when an HD input is down-converted to SD, the output Horizontal resolution can be selected as either

720 pixels (default) or 704 pixels. The choice is made in the Video Output – Advanced panel (see page 50)
and is displayed beneath the output screen. In all other cases the SD Horizontal resolution is 720 pixels.

Under the ARC tab, several sub-sections are f ound allo wing
extended control over how the output will be displayed. For
convenience, ARC presets are available for frequently­encountered aspect ratio conversions.

• These controls are disabled when the ARC Mode
pulldown on the Input Screen is set to Auto or Forced

You can configure the ARC parameters differently for an SD
input than for a 3G/HD input. The card will remember the
different parameters and will load them automatically without
user intervention depending if the video input is SD or
3G/HD. Ensure the card has a video signal of the desired
format before changing the configuration.
When using manual aspect ratio mode (AFD mode is 4:3 or
16:9), the card will remember automatically all the
parameters for the different combinations of input/output
aspect ratio conversions (see the combinations below). This
means you can configure the card once for each type of conversion and then the card will restore the configuration
automatically when the proper input format and input/output aspect ratio is encountered.

• 3G/HD 16:9 to SD 16:9

5.5.1.1 Input section

Input: Crop – Horizontal and Vertical

The crop controls allow selection of a portion of the original image – the amount of horizontal and vertical cropping is
expressed as a percentage of the size of the original image.

The user can manually adjust the level of horizontal and vertical cropping. Horizontal cropping is done on an 8-pixel
basis. Vertical cropping is done on 4-line basis. To achieve non-symmetrical vertical or horizontal cropping, uncheck
the Center box underneath and position the image using the Tilt function described below.

Input cropping changes the scaling factor between the input and the output. If we crop the input (H&V) by 10%, the
output image is resized and scaled by +10%. By providing different H and V cropping, the user can produce an
anamorphic image.

The padlock icon appearing next to the data window allows the data to be “locked”. See the paragraph Locking

controls under Output sub-section below for a discussion of this option.
Input: Tilt

Once a smaller window has been established by cropping the input signal, it can be moved vertically (Tilt, exp res s ed
in lines) within the original image to place the desired portion of the image in view. By default, a Center check box

Figure 5.26 Video Outputs SD – ARC tab

GUIDE TO INSTALLATION AND OPERATION

XVP-3901 | 45

beneath the Tilt scroll box forces the cropping window to be centered on the input window. When it is checked, the
necessary Tilt value will be calculated and displayed in the Tilt data window. You cannot tilt when cropping value is
zero.

Input: Pan

Once this smaller window is established, it can be moved horizontally (Pan, expressed in pixels) within the original
image to place the desired portion of the image in view. A Center check box beneath the Pan scroll box forces the
cropping window to be centered on the input window. When checked, the necessary Pan value will be calcul ated and
displayed in the data window. You cannot Pan if the cr opp ing valu e is zero.

5.5.1.2 Output section

Output: Side Panels / Letterbox

This scrollable data e ntry box is used to s hrink the width of the im age so that th e output im age has blanked areas on
each side of the displayed picture, which occupy the indicated percentage of the screen width. These areas are
symmetric about the c enter, so a setting of 25% side panels would sho w a bar 12.5% of the scr een width on each
side of the image. 25% is the maximum value; entering a smaller value reduces the width of the side panels, but crops
the image top and bottom. This control is disabled when the input is 16:9.

Treatment of Letterbox is similar, except that blanked areas are above and below the image.

Output: Position

This control allows the p os i tion in g of the ou tput pic tur e when side panels or le tter b ox are pr es ent. F or s ide panels, the
picture can be moved tota lly to the left, centered or totally to the right. W hen letterbox is present, the picture can be
moved to the top, to the center or to the bott om of the frame. This control is not a va ilabl e in A uto AFD mode or Forced
AFD mode. The picture will be centered by default when an ARC Preset is selected.

Output: Anamorphism

This control box allows t he output image to be res ized asymm etrically. Anam orphism is expressed in perc ent, where
positive values indicate an increase in width with respect to height, and negative values a decrease in width with
respect to height.

Locking controls
Represented by padloc k icons, these buttons allow th e V Crop , H Crop, Anamorphism and Side Panels controls to be
“locked”. When a c ontrol is locked, user acc ess to that c ontr ol is disabled. Changes to unl ocked controls will not af f ec t
the data values of locked controls. There is some interactivity within the locking function, as follows:

• If either V Crop or H Crop is locked, Anamorphism is unlocked.

• If either Side Panels or Anamorphism is locked, the other is unlocked, along with V Crop and H Crop.

5.5.1.3 Presets section

For convenience in manual operation, several of the most common conversion situations are pre-programmed into the
XVP-3901, and can be quickly accessed. The available Presets change according to the AFD mode and Output
Format selections made using the pulldowns on the input and output screens.

The charts in figures 5.26a and 5.26b illustrate graphically the effect of each preset on the input image.

• Only those presets for which an output is shown will appear on the Video Output panel.

• For example, when the input and output formats are the same, only the Bypass button will appear

• In all cases, a button labeled Custom will appear, and will be selected whenever the parameter settings do not

correspond exactly to one of the available presets

The advantage of using Presets is to provide a unique conversion without having to specify the H&V scaling factor or
the percentage of cropping/side panels and anamorphism. When an ARC Preset is selected, it re-centers the output
picture in case of side panels or letterbox, but it does not affect the output masks.

5.5.1.4 Masks section

Mask: Horizontal and Vertical
Sometimes with aspect ratio conversion, some of the edges of the original image are exposed in the output signal.
Often, there will be artifacts in the source along these edges, extending for several lines vertically or several pixels
horizontally after conversions. Masks are adjustable “curtains” which can be used to frame the output image, coveri ng
up the edge artifacts and leaving a clean transition from image to mask.

Four Scroll boxes with data windows for reporting and direct data entry are used to set mask position on the four sides
of the output image. Top and bottom position are set in lines, while left and right position are set in pixels.
Masks should be adjusted by viewing the output on a video monitor and positioning the masks to cover edge effects
with a minimum loss of clean picture content. Usually masks are the final adjustment to be made. The masking is
shown on the top right Output screen by graying out the masked portion. Note that mask – or Background - color may
be changed in the Advanced tab. The maximum amount of masking that can be introduced depends on the image

5.5.2 SD Output – Timing tab

he Timing tab provides access to timing adjustments which
affect the signal outputs. There are two slider controls, each
with a data reporting box which shows the current value, and
into which values can be typed directly. The total delay is
reported at the top of the window.

Vertical SD (lines): With this adjustment, a value ranging
from –8 to +7 lines, compared to the reference or the
processing delay, may be set. This adjustment can be used
in conjunction with the horizontal timing adjustment.

Horizontal SD (µsec): With this adjustment, a value ranging
from zero to the equivalent of 1 horizontal line in the current
operating format (e.g. ranging from 0 to 63.46 µs for 525-line
operation and 0 to 64.00 µs for 625-line opera tio n) compared
to the reference or the frame boundary, may be set.

Additional Frame Delay: This parameter affects the overall processing delay of the card. It affects both the HD and SD
output by adding supplemental frame delay to the current processing delay. This parameter will add a delay ranging
from 0 to 15 interlaced frames (i.e. steps of 33 ms in 59.94 Hz and 40 ms in 50 Hz) to the current processing delay.
Without a reference, the normal processing delay is 1 frame. You can extend this delay up to 16 frames if the
additional delay is 15. With a reference, up to 15 frames can be added to the frame sync delay which depends on the
timings between the input and the reference.

Note that, in order to compensate for the processing delay of a Dolby-E/Dolby Digital decoder or a Dolby-E encoder
installed on the XVP-3901 or on the companion audio card, the additional frame delay must be set to at least one (1)
frame. On the other hand, if a Dolby Digital encoder is installed, the additional frame delay must be set to at least six
(6) frames for 59.94 Hz formats and at least five (5) frames for 50 Hz formats.

Separate controls are provided for Horizontal and Vertical
detail enhancement:

Horz. Detail Enhancer Mode: this pull-down box controls the
type of horizontal detail enhancement, which may improve
sharpness of textures and contours.

• High Freq boosts high frequencies of the input signal

• Medium Freq boosts medium frequencies of the input

signal

Horz. Detail Enhancer: a slider and a data reporting/entry
box allow the user to select a value in the range 0 (no
enhancement) to 7 (maximum enhancement). The default
value is 1 for HD to SD mode, and 0 for SD to SD mode

Vert Detail Enhancer Mode: this pul l-down box controls the
type of vertical detail enhancement, which may improve
sharpness of textures and contours.

• High Freq boosts high frequencies of the input signal

• Medium Freq boosts medium frequencies of the input signal

Vert. Detail Enhancer: a slider and a data reporting/entry box allow the user to select a value in the range -8 (some
softening) to +7 (maximum enhancement). Set the value to 0 for no enhancement. The default value is 1 for HD to SD
mode, and 0 for SD to SD m ode

5.5.3.2 Background color section

This color patch (black by default) indicates the color that will be
used for the masks, and will therefore surround the output image
when it does not occupy the full output screen. Click on the
Change… button to open the Background Colors window. This
window includes YCbCr sliders with data entry boxes, and a color
preview patch. The color is represented by an 8-bit value for each
component.

• If you have selected an illegal RGB color , it wil l be
flagged as “Invalid RGB” beneath the color patch, and
also within the color patch shown in the Advanced tab if you apply it. This invalid RGB color will not be clipped
by the Gamut correction. Make sure you select a valid RGB color if you care about Gamut errors.

• Colors for HD and SD masks are specified independently when the corresponding output format is selected.

5.5.3.3 HD to SD Output Resolution

Select the output image width (in pixels) when the SD output is down-converted from HD. Choices are: 720 pixels
(default) and 704 pixels.

• Normal SD image width is 720 pixels. In ATSC applications MPEG encoders will crop to 704 pixels for
encoding and the set-top box will stretch back to 720 pixels creating 2% anamorphism. To compensate for
this problem, the user may select 704 pixels using the H Size pull-down. This will compress the down­converted image to 704 pixels instead of 720 pixels. When stretched back to 720 pixels by the set-top box,
the anamorphism will be eliminated. This functionality is only available for HD-to-SD conversions. The factory
default for this parameter is 720 pixels. The value selected here appears in the pull-down beneath the Output
Screen at the top of the panel when an HD-to-SD down-conversion is selected.

5.5.4 SD Output – Meta tab

The Meta tab provides resources to deal with Metadata incorporated into the incoming signal. It has three associated
sub-tabs, described below.

5.5.4.1 Warning messages

Warning messages may appear at the bottom of the Meta and AFD panels when conflicts arise because of the
settings. See Figure 5.28 for an example. The possible messages and their meanings are as follows:

• AFD/ Timecode line insertion conflict. Refer to manual. [message in red letters]
Conditions: HD to SD, same line set for AFD and Timecode 1 (or Timecode 2) insertion (duplicate time code
included)
Consequences: Since DVITC timecode and SMPTE-2016 AFD cannot reside on the same line, timecode
data will not appear on the insertion line but AFD data will be inserted.

• AFD/ VLI line insertion conflict. Refer to manual. [message in red letters]
Conditions: Both AFD and VLI flags are inserted and AFD is set to line 14 during 59 Hz or line 11 during 50
Hz operation.
Consequences: Since the SMPTE-2016 AFD cannot reside on the same line as VLI, the VLI flag will not
appear on the insertion.

• Dolby Metadata/Tim ecode line insertion conflict. Refer to manual. [message in red letters]
Conditions: HD to SD, same line set for Dolby Metadata VANC Stream1 (or Stream 2) and Timecode 1 (or
Timecode 2) insertion (duplicate time code included)
Consequences: Since DVITC timecode and Dolby metadata cannot reside on the same line, timecode data
will not appear on the insertion line but Dolb y metada ta data will be inserted.

• Dolby Metadata/VLI line insertion conflict. Refer to manual. [message in red letters]
Conditions: HD/SD to SD, line 14 (59 Hz) or line 11 (50 Hz) set for Dolby Metadata VANC Stream1 (or
Stream 2) and VLI insertion enabled
Consequences: Since VLI data is transmitted on line 14 for 525 output signals and line 11 for 625 output
signals, VLI data will not appear on line 14 (or line 11 for 625) but Dol b y metadat a data will be inserte d.

• Dolby Metadata/Teletext line insertion conflict. Refer to manual. [message in red letters]
Conditions: HD/SD to SD (625 only), same line set for Dolby Metadata VANC Stream1 (or Stream 2) and
teletext insertion
Consequences: Since teletext and Dolby metadata cannot reside on the same line, teletext data will not
appear on the insertion line but Dolby metadata data will be inserted.

• Teletext/VLI line insertion conflict. Refer to manual. [message in red letters]
Conditions: HD/SD to SD (625 only), line 11 enabled for teletext and VLI insertion enabled

GUIDE TO INSTALLATION AND OPERATION

• Timecode 2 will overwrite Timecode 1 insertion. Refer to manual. [message in red letters]

Conditions: HD to SD, same line set for Timecode 1 and Timecode 2 insertion (duplicate timecode included)
Consequences: Any LTC type incoming timecode will be inserted over any VITC type incoming timecode
specified by the Timecode 2 SD Insertion Line parameter.

• AFD insertion will overwrite incoming TC/Teletext on insertion line. Refer to manual. [in blue letters]

Conditions: SD to SD, both AFD and VBI insertion enabled
Consequences: Since timecode and SMPTE-2016 AFD cannot reside on the same line, any incom ing

timecode is blanked and the AFD data is inserted. This occurs on the selected AFD insertion line.

• Dolby Metadata insertion will overwrite incoming TC/Teletext on insertion line. Refer to manual. [in blue letters]

Conditions: SD to SD, both Dolby Metadata and VBI ins ertion ena bl ed
Consequences: Since Dolby metadata and ancillary data like timecode cannot reside on the same line, any

incoming timecode is blanked and Dolby metadata is inserted. This occurs on the selected Dolby metadata
insertion line.

• Dolby Metadata/AFD insertion will overwrite incoming TC/Teletext on insertion line. Refer to manual. [in blue

letters]

Conditions: SD to SD, both Dolby Metadata and AFD including VBI insertion enabled
Consequences: Since Dolby metadata, AFD, and ancillary data like timecode cannot reside on the same line,

any incoming timecode is blanked and Dolby metadata or AFD is inserted. This, of course, shall occur on the
selected Dolby metadata or AFD inser ti on line.

5.5.4.2 Meta / Meta sub-tab

Closed Caption section

Presence: this icon turns green in the presence of incoming
EIA-708-B or EIA-608-B closed captioning data when an
3G/HD source is installed or when line 21 closed captions are
detected when an SD source is installed.

Insertion: The pull-down is used to select between Auto or
OFF. Availability of these controls is affected by whether or

not Line 21 of the input SD or output SD signal has been
configured as blanking; see SD Input/Output Config
subsection below for details.

When Auto is selected, closed captioning information is
processed as follows:

3G/HD to SD Downconversion:

As described in EIA-708-B, closed captioning within a 3G/HD
signal is embedded in the form of ANC packets. The XVP­3901 extracts all NTSC legacy (compliance) closed captions

Figure 5.31

from within incoming EIA-708-B DTV closed captions, buffers, and re-inserts the data within line 21 of the output SD
signals as per EIA-608-B standard. Processing is restricted to NTSC CC information (Service 0) only.
The XVP-3901 also supports incoming EIA-608-B CC packets conforming to SMPTE 334M. However, EIA-708-B
packets have priority. If both are embedded in the source, the EIA-708-B packets are decoded, as explained above,
and the EIA-608-B packets are discarded. If no EIA-708-B packets are detected, EIA-608-B packets are automatically
extracted if detected.

Closed captions insertion is disabled for 50Hz and 1080p23/1080p23/1080p25/1080p29 sources.

SD to SD operation:
In order to allow the XVP-3901 to properly handle incoming closed captions on line 21, make sure to set SD
Input/Output Config to Blanking and make sure to set Insertion to Auto.

• Audio, closed-capti oning, time-code, and AFD data is not handled by this parameter. The only exception is time

code during SD to SD operation, in which case the user must use this parameter to enable/disable time code
insertion.

• SD to SD: All incoming HANC packets within H blanking, VANC packets within VBI, and VBI lines may be
bypassed to the output.

5.5.4.3 Meta / Namedropper sub-tab

Namedropper is a method of inserting control information for
down-stream graphics inserters. It is a waveform-shape
located on line 18 in SD, but a VANC packet on line 11 in
HD.

The XVP-3901 detects the presence of Namedropper data in
the program arriving at its input, and flags it using the status
icon in this panel, which turns green when Namedropper

Figure 5.

GUIDE TO INSTALLATION AND OPERATION

XVP-3901 | 53

data is detected.

5.5.4.4 Meta / Timecode sub-tab

If the input is 3G or HD SDI, the ATC packet will be transcoded
to SD only when ATC timecode is present on the HD input
video. When enabled, timecode insertion is automatic when
there is embedded timecode in the source.

• The XVP-3901 supports two types of incoming 3G/HD

ATC timecode conversion - VITC timecode and LTC
type timecode.

• Timecode 1 parameters handle VITC type timecode

whereas LTC type timecode is handled by Timecode 2
parameters.

• The XVP-3901 does not pass LTC type timecode within

input HD formats
1080p23/1080p23sF/1080p25/1080p29.

• Timecode binary group data is not guaranteed for

1080p23/1080p23sF/10 80 p 25/ 1 080 p29 in put HD for m ats, but it will be transparent for all other input formats.

Presence: A presence icon is available for each type of incoming ATC packet. The Timecode 1 Presence icon turns
green when VITC timecode is detected and the Timecode 2 Presence icon turns green when LTC timecode is
detected. If the input is SD, then the presence of each icon depends on the selection of the SD Detection Line
parameter.

SD Detection Line: This parameter is only available when the input signal is SD SDI, and is used only for timecode
presence. Select AUTO mode to automatically detect the line that contains the timecode. If time code appears on
multiple lines, the first is selected. Select a specific line if desired; this allows a choice to be made when multiple time
code lines are present.

SD Insertion Line: the line on which timecode is to be inserted is selectable through a pull-down menu, between lines
10 and 20 for 525-line output, and between lines 7 and 22 for 625-line output.

• This control is disabled when the input is SD

Duplicate: forces a second copy of the time code to be inserted on the 2

nd

line following the selected line. For
example, selecting line 14 for time code insertion, and turning timecode duplication ON, will result in time code being
inserted into both lines 14 and 16. Note that time code cannot be inserted on lines outside the allowable range, so for
example, if line 19 is selected for time code insertion in a 525 line output, and timecode duplication is turned ON, the
duplicate time code which would have appeared on line 21 will not be inserted because the upper bound for time code
is line 20. Thus, the timecode duplication function has no effect when the selected line for time code is 19 or above for
525-line outputs, or 21 or above for 625-line outputs.

• This control is disabled when the input is SD

Insertion: Insertion options are available through a pull-down menu, offering these choices:

AUTO: Time code is inserted if present; insertion is disabled if no time code is present.
OFF: Time code insertion at the output is disabled.

• This control is disabled when the input and output are both SD. In this case, VBI Blanking may be used to
enable/disable time code insertion – see Blanking sub-section above

Copy and Redistribution Control (CGMS)

The Presence icon is green when CGMS information is detected within incoming SD line 21 (CEA-608) or HD (CEA­708 NTSC bytes) closed-captions, and gray otherwise. This presence icon is held green for 10 seconds after CGMS
information has stopped being detected.

Note: In order for CGMS information to appear at the outputs, you must enable Closed Captions insertion for the
intended output. The control is found on the Video Outputs/Meta/Meta subtab; see section 5.5.4.2 on page 51.

Insertion: Use the pulldown to turn insertion ON or OFF.

• When ON, information is inserted according to the selection made in the CGMS-A pulldown and the
Redistribution Control Descriptor (RCD) checkbox. Any incoming information is overwritten.

If no closed-captions are detected at the input, this feature will effectively become a CGMS generator.

• One copy permitted

• No copy permitted

Redistribution Control Descriptor: select this checkbox to force the RCD bit found within the CGMS XDS packet to 1.

For a full description of CGMS control and its purpose, refer to the CEA-608 standard.

5.5.4.6 Meta / Teletext sub-tab

In 50 Hz operation only, incoming OP-47 packets in HD
signals can be converted to Teletext and inserted in the SD
output. This panel configures this functionality.

HD Inputs – incoming OP-47 packets in the HD signal are
converted to Teletext and inserted in the outg oi ng SD s ignal.

• The Incoming Teletext Presence indicators 7 to 22
represent SD line number data detected in any
incoming OP-47 packet. For example, if presence
indicators 8 and 10 are turned on, this indicates
detected OP-47 data is carrying teletext data derived
from (or targeted for) SD lines 8 and 10.

• The SD Output Teletext Insertion Lines checkboxes
are used to select the SD output lines that can receive

Figure 5.35

Video Outputs SD - Meta/Teletext tab

GUIDE TO INSTALLATION AND OPERATION

56 | XVP-3901

teletext data from the incoming OP-467 packets. The actual assignment of data to these lines is determined by
the mode selected in the Insertion Mode pulldown.

The Insertion Mode pulldown offers two modes of operation:

• Auto – Teletext data will be inserted on the enabled lines, represented by the SD Output Teletext Insertion
Lines checkboxes, only if incoming OP-47 packets carry teletext data targeted for these lines

• Bulk – the teletext will be inserted in the lines selected in the checkboxes above the pulldown, in the order of
arrival (first line detected in incoming OP-47 packets is inserted in the first line checked, etc). If there are more
incoming lines than lines selected, the extra lines will be lost. If there are fewer incoming lines than lines
selected, the extra selected lines will not carry any teletext. For example, if Lines 9, 11, and 14 are selected
and presence indicators 15, 16, 19, and 20 are tur ned on, then det ec ted OP -47 packets with embedded data
from lines 15, 16, and 19 will be inserted on SD output lines 9, 11, and 14 respec ti vel y. The data from line 20
will be lost.

SD inputs – incoming teletext is passed through to the output as received; the lines cannot be changed (Pass mode).

• The Incoming Teletext Presence indicators 7 to 22 indicate the SD lines where teletext data, conforming to
ETSI EN 300 706, has been detected.

• The SD Output Teletext Insertion Lines checkboxes are active, and can be configured so as to be ready when
the input is switched to an HD source. They have no effect on an SD source..

Current Mode – this databox displays the current operating mode – AUTO, BULK or PASS

5.5.5 SD Output – AFD tab

The Active Format Descriptor (AFD) flag is used to identify
the aspect ratio and protected areas of a video signal. The
XVP-3901 uses this flag in some cases to adjust the output
aspect ratio and image cropping to obtain the best possible
presentation of the image. The AFD flag is implemented
differently in SD and HD:

• In HD, the AFD flag (SMPTE 2016) is sent in an ancillary
packet, normally found on line 11 in the vertical ancillary
space.

• In SD, the AFD flag may be sent as a VLI signal (RP 186),
as a WSS signal (ITU-R BT.1119-2) for PAL only, and as
an AFD packet (SMPTE 2016).

When an AFD flag is present at the input, the card can
perform an automatic adjustment of the aspect ratio. See the
appendix for more details.

5.5.5.1 Default settings section

Default/Forced: this text box is labeled according to the
mode selected in the Input Screen pulld o wn in the Video
Output Group – see page 42.

• In AUTO mode, labeled DEFAULT and shows the current default AFD code to be used if no valid AFD code is

detected at the input.

• In FORCED mode, labeled FORCED, and shows the code that is forced into the system input regardless of the

actual input code.

• In 4:3 (SD input) or 16:9 modes, the data box is empty and the controls are grey. In these modes, ARC settings

can be manually set using the ARC tab controls.

Change: Click the Change button to open the Select AFD
panel showing the available AFD codes that could be
used as the default. Click on one to select it, then click

Apply or OK at the bottom of the panel.
Keep Last: click in this checkbox to use the last detected

AFD code at the input as the default code to be used in
the Auto mode when no AFD flag is detected. This box is
disabled in the Forced mode.

5.5.5.2 Config section

Incoming – the three types of AFD are shown, with a

presence icon for each, and a pulldown to establish the
priority of each type. The priorities are reset with each
new selection; e.g. if AFD is 1 and VLI is 2, and you use
the pulldown to choose VLI priority as 1, then AFD will be
bumped down to 2.

• Ignore a specific flag completely by selecting “Don’t
use” as its priority level.

The available types depend on the input format – AFD
only for HD inputs; AFD and VLI for SD-59.94 Hz inputs,
and all three types for SD-50 Hz inputs.

The set priority is used only during input AFD AUTO
mode. The XVP-3901 will examine the incoming data in
the selected order of priority in order to extract the AFD data. If, in AUTO mode, an AFD flag is set to priority 1 and is
missing at the input, the XVP-3901 will use the incoming AFD flag set to the next priority level.

The Detected box shows the AFD code detected.
Outgoing – on the SD output, the AFD code shown in the Inserted box will be inserted in up to three different formats

simultaneously. Supported formats are shown; select their respective checkboxes to enable insertion. AFD will be
inserted in the line selected in the Insertion Line pulldo wn. No te that VLI is normally inserted on line 14, so if AFD is
placed on line 14 using the pulldown, VLI will not be ins er ted.

Field Extract AFD & VLI – Select the field from which AFD and VLI will be extracted:

• Field 1

• Field 2

• Field 1 & 2

Note that this selection applies to both SD and HD outputs, and can also be set from the equivalent panel in the HD
Output section (see page 40).

Alternate ARC section

When the output is 4:3 SD, if the input AFD setting is set to Auto or Forced mode and the input AFD is a full screen
16:9 (AFD code 16:9_2 or 16:9_8), the output image may be scaled in one of 2 ways. Use the pulldown to select
which will be used:

• Letterbox: Uses the traditional 16:9 letter box within a 4:3 frame where there is no loss of image.

• Center Cut: The XVP-3901 provides a second alternative – the input is horizontally cropped about the center to

create a full screen 4:3 image. Choosing this alternative essentially removes 25% of the original image.

GUIDE TO INSTALLATION AND OPERATION

58 | XVP-3901

5.5.6 SD Output – De-interlacer tab

Some interlaced video sources are film-based originating from 24p film images. For optimum scaling performance, it
would be best to de-interlace this type of source by simply merging the source’s fields to recreate the original 24p
image, thereby introducing no de-interlacer artifacts prior to scaling and format conversion.

Film mode: When The Film Mode selection is set to ON, the
XVP-3901 monitors the input for film-based sequences and
applies the proper algorithm.

Film detection is provided for 3:2, 2:2 (59Hz and 50 Hz
sources) and 5:5 sequences.

Video Over Film: When the film mode is enabled, turn ON
the Video-Over-Film (VOF) function to detect and bypass
field-merging on certain video regions such as scrolling video
characters over an entire film frame, thereby preventing any
unwanted combing effects.

There is only one de-interlacer on the card. Any changes made within this tab will be copied over to the De-interlacer
tab in the Video Output – 3G/HD panel.

5.6 Audio Proces sing panel

The Audio Processing panel provides full audio processing
and delay parameters for up to 32 channels. The first 16
channels come from the embedded input channels and/or the
discrete AES inputs. The second set of 16 channels comes
from the output channels of the following modules:

• Dolby E/Digital (AC-3) decoder module(s)

• Linear Acoustic’s upMAX

tm

module(s)

• Downmix

The 32 processed audio channels can be assigned later to
the Dolby-E/Digital encoder modules, the 3G/HD out pu t
embedder, the SD output embedder, the discr ete AE S
outputs, or sent to one or two DAP or UAP companion cards
using the A-BUS. To enable the “Audio Processing”
functionality, you must either have enabled the audio option
or you must have an external audio card connected through
the ABUS.

You can configure the audio processor differently for an SD
input than for a 3G/HD input. The card will remember the
different parameters and will load them automatically without
user intervention based on whether the video input is SD or
3G/HD. Ensure the card has a video signal of the desired

format before changing the configuration.
Group Detected section

Status indicators turn green when audio groups 1, 2, 3 or 4 are detected in the incoming signal. The Group Detected
warning color can be configured by the user in the Alarm Config panel (Sect. 5.20)

Presence warning color can be configured by the user in the Alarm Config panel (Sect. 5.20)

5.6.1 Audio Processing Tab

CH 1-4, …. CH 29-32 Tabs

Each of these tabs controls Levels, Fixed Delays and Silence detection for four audio channels; each channel is
provided with a set of controls.

Levels sub-tab: grouped by pair of channels, each channel
has the following controls:

Level (slider and input box): Sets the audio gain from

-96 to 12 dB in 0.5 dB steps. For non-PCM audio, the
level value is overridden to 0 dB.

Mute (speaker button): Mutes the selected audio
channel

Phase Invert: When checked, inverts the selected
audio channel phase.

Lock: “Locks” both channel sliders together for levels
and delay (coarse only), so that moving one slider
moves the other one as well.

Fixed Delay sub-tab: although the XVP-3901 automatically
matches audio and video throughput timing, provision is made
for the user to insert an audio delay offset from the nominal
value, in order to deal with problems such as lip-sync error s
and audio phase alignment in the incoming feed. For each
channel, two sliders allow the delay to be adjusted.

• Coarse – adjusts the delay in milliseconds, over a range
of values that depends on the Additional Frame Delay
set on the timing tab in the Video Output group (see
page 34), as follows:

Additional Adjustment Adjustment
F rame Delay Range Range
(59.94 Hz) (50 Hz)

0 0 to 2000 ms 0 to 2000 ms
1 -33 to 2000 ms -40 to 2000 ms
2 -66 to 2000 ms -80 to 2000 ms
3 -99 to 2000 ms -120 to 2000 ms

… … …
15 -500 to 2000 ms -600 to 2000 ms

• Fine – adjusts the delay in audio sample increments,
from -100 to +100 samples.

Silence sub-tab
This tab sets the card’s behavior in the event of a loss or

absence of audio signal. The Signal Presence indicators are
then triggered according to these sett in gs:

Silence Detect: select which audio channels to monitor for
audio silences by checking their boxes. This enables the
signal presence indicators to change color when there is no
signal present which activates the audio silence alarm.
Otherwise, when checkboxes are not checked, the signal
presence indicator turns grey and the audio silence alarm is
not activated

Threshold: Signal absence is declared when the signal level
is lower than the signal threshold for a duration longer than
the No Signal Delay. The threshold can be set to -72, -66, -

60, -54, -48 dBFS. The default value is –60 dBFS.
No Signal Delay: The period for which signal must be

continuously absent before an alarm can be triggered can be
adjusted from 3 to 255 seconds in preset steps: 3, 5, 7, 10,
15, 20, 30, 40, 50, 60, 90, 120, 180, 210, 240, 255 sec. The default value is set to 15 seconds.

5.6.2 Downmix tab

This tab provides resources to control the downmix of a “5.1
channel” surround-sound audio signal into an LtRt or LoRo
stereo pair. The 5.1 terminology refers to six discrete audio
channels, with the low frequency effect (LFE) channel of
limited bandwidth designated as the “.1” channel. The
downmix can be done using any of the 32 audio channels
processed by the audio processor using the Input Channels
controls in the interface.

Input Channels: Use the 6 pulldowns to select the source
channels for the downmix process.

Downmix:

Operating Mode: Use the pulldown to select the downmix
operating mode:

• OFF: Downmix is disabled. Output channels pass
through unchanged.

• Manual: Downmix follows the downmix parameters
manually configured by the user.

• Follow Metadata Path 1: Downmix follows the downmix
parameters of Metadata Path 1.

• Follow Metadata Path 2: Downmix follows the downmix
parameters of Metadata Path 2.

Level Normalization: use the pulldown to select the type of
normalization to be applied on the downmix output level.

• OFF: Downmix output level is not normalized. Clipping may occur depending on the input channel levels and

the selected mix levels.

• Level A: Downmix output level is normalized based on the applied mix levels to provide a uniform output over

the range of mix levels available. Clipping will never occur, even with full scale input channels and mix
levels.

• Level B: Downmix output level is normalized based on the channel configuration to provide a uniform output

loudness between 3/2 and 2/0 programs. Downmixing a 3/2 program produces a loudness attenuation
compared to the same program in 2/0 at the same input loudness. To provide a uniform output loudness,
a loudness attenuation is applied only on 2/0 programs. If the operating mode is Follow Metadata , the
channel configuration is given by the AC-3 coding mode parameter in the metadata. If the operating
mode is Manual, the channel configuration is given by the selected mix levels: a 2/0 channel configuration
is achieved by setting Center, Surround, and LFE Mix Levels to Mute. Any other combination of mix
levels is assumed to be a 3/2 channel configuration. Level-B normalization also inc ludes Lev el-A
normalization, based on the applied mix levels. Clipping will never occur, even with full scale input
channels and mix levels.

• This selection is not available when Oper. Mode is OFF.

Output Channels: Select the audio channels whose content will be replaced by the output of the downmix processor

• 7&8

• 15&16

• 23&24

• 31&32

• This selection is not available when the Operating Mode is OFF (downmix disabled).

Manual Downmix Config / Default Metadata Config

The heading of this area of the panel changes depending on the selection in the Operating Mode pulldown above, but
the available controls are the same in both cases.

• Operating Mode = Manual – the controls are used to set up the Manual Downmix parameters.

• Operating Mode = Follow Metadata Path 1 or 2 – the controls are used to set up the def ault do w nmix

parameters for situations where the selected metadata path contains no data.

Mode: this pulldown menu selects the downmix mode:

• LtRt: Enables the downmix of 5.1 channels into an LtRt (Left total Right total) matrix surround encoded

stereo pair. The input signals on the channel pair selected as the Output Channels are discarded.

• LoRo: Enables the downmix of 5.1 channels into an LoRo (Left only Right only) stereo pair, which is a

conventional stereo signal. The input signals on the channel pair selected as the Output Channels are
discarded.

Dialnorm: this pulldown selects the dialog normalization level. Select OFF to prevent the downmix from applying the
dialnorm.

[OFF, -1 dBFS, -2 dBFS, -3 dBFS, ………, -31 dBFS]

Center Mix Level – sets the center channel downmix level to the selected value

[+3 dB, +1.5dB, 0 dB, -1.5 dB, -3 dB, -4.5 dB, -6 dB, Mute]

Surround Mix Level – sets the surround channels (Ls & Rs) downmix level to the selected value

[+3 dB, +1.5dB, 0 dB, -1.5 dB, -3 dB, -4.5 dB, -6 dB, Mute]

LFE Mix Level – sets the LFE channels downmix level to the selected value.

[+10 dB, +9 dB, +7.5, +6 dB, +4.5 dB, +3 dB, +1.5dB, 0 dB, -1.5 dB, -3 dB, -4.5 dB, -6 dB, Mute]

• Note: The LFE Mix Level pulldown sets the LFE downmix level for both Manual and Follow Metadata Path 1 or

2 operation modes, whether or not the metadata is present in the selected path.

Follow Metadata Config:

This section reports on Metadata presence in the selected path if the Follow Metadata Path 1 or 2 Operating Mode is
selected. The four data boxes below the Metadata status icon indicate the current mode, plus the values in use for
Dialnorm, Center Mix Level and Surround Mix Level.

5.6.3 AES Inputs tab

The status icons at the top of the tab indicate which Groups
and discrete AES are detected, and which of the 32 channels
have signal present.

Audio Proc Input Selection

This section provides a selection between the embedded
audio and the discrete AES inputs. Channels 1 to 8 will
always be the first 8 embedded channels. However,
channels 9 to 16 can be either embedded channels 9 to 16
or the 8 discrete channels from the 4 AES inputs, selected
using the pulldown.

Sample Rate Converter

Use the pulldowns to select between OFF and Auto for each
of the four AES.

• OFF: Sample rate conversion is disabled. Use only

if the AES input is always 48 kHz synchronous
to the video input OR if the AES input carries
non-PCM audio (Dolby or other) with its
channel status indicating “Linear PCM”.

Figure 5.46 Audio Proces si ng - AES Inputs tab

GUIDE TO INSTALLATION AND OPERATION

XVP-3901 | 63

• AUTO: Sample rate conversion is automatic, based

on the input audio type. Sample rate
conversion is enabled for PCM audio, and
bypassed for non-PCM au d io.

5.6.4 Status tab

The Status tab reports the type of audio present at the input
and the Dolby-E alignment.

Audio Type Status:

• PCM – the audio channel carries PCM audio
(orange)

• Dolby E – the audio channel carries Dolby E
encoded audio (blue)

• AC3 – the audio channel carries Dolby Digital (AC-3)
encoded audio (violet)

• NPCM – the audio channel carries non-PCM oth er
than Dolby E or Dolby Digital (AC-3) (yellow).

Dolby-E Alignment:

• When Dolby-E audio is present, this panel will
display the offset/dela y between the Dol b y-E and the
video output timing of the card. You may click the
Auto Align button to automatically adjust the audio
timing delay to ensure a perfect alignment with the
video. This is equivalent to changing manually the
audio delay in the audio processor . If you change
the output timing of the card or the video output
format, you may have to re-align the Dolby-E.

• The offset is not available for any type of audio other
than Dolby-E.

The measured Dolby-E offset can be a positive OR a
negative value. A negative value indicates the Dolby-E is in
advance compared to the video and additional delay should be added to the audio channel pair.

A positive value indicates the Dolby-E is late compared to the video and the audio delay must be reduced for this
channel pair. Sometimes, the audio delay cannot be compensated because it would mean to have an audio delay
lower than the processing delay of the card. In this case, you have to add an extra frame delay to the video to provide
more range to the audio delay.

5.7 Dynamic P r oc. panel

This panel provides controls for dynamic processing of the audio passing through the XVP-3901. The audio
processing (XVP-3901-OPT-AUD) and the dynamics processing (XVP-3901-OPT–DP) options must be activated to
access this functionality. Individual and independent controls are provided for each of the 32 channels.

These parameters affect the output audio channels (HD/SD embedded and AES), the audio channels assigned to the
Dolby-E/Digital encoder modules, as well as the audio channels sent to the DAP or UAP companion cards.

Note that unlike the audio processing configuration, only one (1) dynamic processing configuration is saved by the
card, regardless of the input format (3G/HD or SD).

• Access the individual channel controls through 4
master tabs and sub-tabs

The functionality of these controls is identical for each
channel, and is explained here.

The upper right-hand corner of each tab contains a graphic
depicting the transfer characteristic of the channel as
configured by the current dynamic processing settings.
Images will be shown below to illustrate the effect of the
various controls

Mode

Use the pulldown to select the operating mode for this
channel, from among these options:

• Mono: applies the dynamics processing settings
only to the selected channel

• Stereo: applies the dynamics processing settings to
the channel pair (e.g. 1 & 2, 7 & 8, etc.)

• Group 1: applies the dynamics processing settings
only to the channel assigned to Group 1

• Group 2. applies the dynamics processing settings
only to the channel assigned to Group 2

Click the Bypass Settings checkbox to bypass all the dynamics processing settings set up in this panel for this
channel.

Dynamic Gain

Sets the audio dynamic gain from 0 to 24 dB (in 1 dB steps) applied to
the selected channel. The dynamic gain is applied at the end of the
dynamics processing chain.

Limiter Threshold

A limiter is a type of compressor designed for a specific purpose, to limit
the level of a signal to a certain threshold. Whereas a compressor will
begin smoothly reducing the gain above the threshold, a limiter will
almost completely prevent any addition al gain abo ve t he thresh ol d. A
limiter is like a compressor set to a very high compression ratio (typically
1/∞).

For example, if the limiter threshold is set to -20 dBFS and the input
signal level is -10 dBFS (10 dB above the threshold), t he signal level at
the output of the limiter will be -20 dBFS.

• Use the Limiter Threshold slider to set the threshold from -20 dBFS to 0 dBFS (1 dB steps).

XVP-3901 | 65

Compressor

Audio compression is a method of reducing the dynamic range of a signal. All signal levels above the specified
threshold are reduced by the specified ratio. When the signal level exceeds the threshold, the compressor will begin
smoothly to reduce the gain, following the attack time, until the output level reflects the specified compression ratio.
When the signal level is below the threshold, the compressor will begin smoothly to increase the gain, following the
release time, until the output level matches the input level.

For example, if the compressor threshold is set to -20 dBFS and a ratio
of 1/2, and the input signal level is -10 dBFS (10 dB above the threshold),
the signal level at the output of the compressor will be smoothly reduced
to -15 dBFS (following the attack time). Then, if the input signal level
suddenly drops to -30 dBFS (10 dB below the threshold), the signal level
at the output of the compressor will smoothly go back to -30 dBFS
(following the release time).

Use the Attack Time pulldown to set the attack time. The attack time
specifies how fast the compressor will reduce the gain:

• Possible values: 1 ms, 5 ms, 10 ms, 20 ms, 40 ms, 80 ms, 160 ms.

Use the Release Time pulldown to set the release time. The release time specifies how fast the compressor will
increase the gain:

• Possible values: 48 dB/s, 36 dB/s, 24 dB/s, 18 dB/s, 12 dB/s, 9 dB/s, 6 dB/s

Use the Ratio pulldown to set the compression ratio (i.e. slope of the transfer curve). The compression ratio specifies
how much the output level changes with respect to the input level:

• Possible values: 1/1 (OFF), 1/1.25, 1/1. 5, 1/1.7 5, 1/2, 1/3, 1/4, 1/8, 1/1 6

Use the Threshold slider to set the compression threshold (i.e. break point in the transfer curve). The compression
threshold specifies the level above which the compressor will process the signal.

• Range -60 dB to 0 dB

Expander

Audio expansion means to expand the dynamic range of a signal. It is basically the opposite of audio compression.
Like compressors and limiters, an audio expander has an adjustable threshold and ratio. Whereas compression and
limiting take effect whenever the signal goes above the threshold, expansion effects signal levels below the threshold.
Any signal below the threshold is expanded downwards by the specified ratio.

For example, if the expander threshold is set to -40 dBFS and a ratio of 2/1, and the input signal level is -60 dBFS (20
dB below the threshold), the signal level at the output of the expander will be reduced to -80 dBFS. Then, if the input
signal level suddenly increases to -30 dBFS (10 dB above the threshold), the signal level at the output of the
expander will go back to -30 dBFS.

Use the Ratio pulldown to set the expansion ratio (i.e. slope of the
transfer curve). The expansion ratio specifies how much the output level
changes with respect to the input level :

• Options available: 1/1 (OFF), 1.125/1, 1.25/1, 1.375/1, 1.5/1,

1.625/1, 1.75/1, 1.875/1, 2/1

Use the Threshold slider to set the expansion threshold (i.e. break point
in the transfer curve). The expansion threshold specifies the level below
which the expander will process the signal.

• Range -80 dB to -40 dB

• The right-hand portion of this section shows the output channels of the dynamics processor on level meters, as
found in the RALM panel.

• The left-hand side shows approximately how much dynamic processing is being applied to the signal (by
amplitude) on a channel basis.

• The example shown above is the result of substantial compression being applied to Channel 1

5.8 Audio Outputs panel

This panel provides additional audio processing for the 16
audio channels embedded in the 3G/HD and SD output, and
for the four AES outputs:

• audio channel shuffling

• level adjustment

• mixing

• audio embedding mode.

The XVP-3901 may be paired with up to two DAP or UAP
cards for additional audio channel inputs to the mixers and
for discrete AES/analog outputs.

You can configure the audio output shufflers/mixers (3G/HD,
SD and AES) differently for an SD input than for a 3G/HD
input. The card will remember the different parameters and
will load them automatically without user intervention based
on whether the video input is SD or 3G/HD. Ensure the card
has a video signal of the desired format before changing the
configuration.

The panel has a set of tabs at the top to allow the
appropriate audio channels to be accessed (figure 5.49). The
available controls are virtually identical in all cases, so they
will be described only once.

5.8.1 CH 1-2, CH 3-4, … CH 15-16 tabs, and AES1, … AES4 tabs

Each of these tabs provides all necessary controls for the
output mixers. The example shown is for 3G/HD Output, CH
1-2, but all panels have the same controls.

Operation Mode (Off, A, SUM(A+B), Mix) : This menu allows
the source(s) of each output channel to be selected – a
single channel, the sum of two channels or a mix of two
channels.

Off: The output channel is muted.
A: The output channel is the channel source (ABUS

Select and Channel) selected in sub-menu SOURCE A.
SUM (A+B): The output channel is the sum of the two

channels sources (ABUS Select and Channel) selected
in sub-menus SOURCE A and SOURCE B.

• If you select this option, the S UM (A+B) Level pull-
down is activated, allowing you to reduce the level
of the summed output (0dB, -3dB or -6dB).

Mix: The output channel is a mono mix of the (ABUS
Select and Channel) selected in sub-menus SOURCE A

and SOURCE B.
Mix 4Ch: This mode allows a 3-input or 4-input mix on
the chosen even output. A standard 2-input mix is
available on the odd output. On the same tab, the two
selected sources of the even channel are mixed with the
one or two selected sources of the odd channel. The four sources are mixed, with the level of each source

adjusted using its slider or data entry box. You can swap the odd and even output by putting a check mark in the
Channel Swap (1&2) checkbox. Note that in the Mix 4Ch mode, if the Mute box is checked, only the even
channel sources will be muted, the odd channel sources will still pass to the out p ut .

Note: in the case of SUM and MIX, if either of the two input channels is non-PCM, the output will always be
SOURCE A

Mute: Mute the audio channel by checking this box. In the MIX4Ch mode, checking this box will mute only the

sources of the selected output channel.

Source A & Source B: These sub-sections allow the source channels (A and B) to be selected for each output
channel.

ABUS Select: V, A1, A2: selects the embedded input audio (V), one of two audio companion cards (A1 or A2
channels 1-8) or one of two Dolby decoder modules installed on companion cards (A1 or A2 channels 9-16) to be
used as the source for this channel. Note: The ABUS card system is configured in the ABUS panel.

Channel: Channel 1, …, Channel 16: selects the channel to be used from the selected audio source.
Level (dB): Sets the audio gain of the channel source from -96 to +12 dB in 0.5 dB steps. For non-PCM audio,

the level value is overridden to 0 dB.

5.8.2 Config tab

A Config tab is available in the 3G/HD tab and the SD tab,
but not in the AES tab,

In each case, the tab contains only an Output – Audio Insert
pulldown.

Use the pulldown in this tab to enable (AUTO) or disable
(OFF) audio embedding in the output.

• When OFF is selected, no audio is embedded in the
HD output.

• When AUTO is selected, only those audio groups
containing at least one audio channel will be
embedded at the output.

For SD outputs, the number of bits to be embedded must
also be selected, and so the options in the pulldown are:

• OFF

• Auto 20 bits

• Auto 24 bits

Any of these modul es can be inser ted in either socket 1 or 2. W hen a module is installed
in one of these sockets, its controls will appear in the appropriate tab in this panel.

See Section 6 beginning on page 109 for detailed descriptions of all of the available
modules and their associated control panels.

The Dolby decoder, Linear Acoustic upMAX

(upmix), Linear Acoustic AeroMAXtm (ALC) or Jünger Audio Lev el

Magic

tm

(ALC) modules are located at the input of the audio processing path, as shown in this block diagram of the
XVP-3901 audio processing section. If both modules are installed, the Dolby decoder module is located before the
upmix or ALC

modules in the audio processing path, to allow the decoded channels to be upmixed. The Dolby-

E/Digital encoder modules ar e located at the end of the audio processing path.
The output channels of the above modules are always fixed and depend only on the module socket number in which it

is inserted. The outputs for module 1 will always be in the range 17 to 24. The output for module 2 will always be in
the range 25 to 32. Refer to the table below for a quick overview of the output channels versus the installed modules
and their module position:

Installed Module

It must be noted that the MOD-LA-DUP-701 has only 6 outputs and the MOD-DOLBY-ENC-D-2/E has only 2 outputs.
In these cases, only the first 6 or 2 channels are used. The MOD-LA-ALC-X-YYY and MOD-JA-ALC-X-YYY modules
may have from 2 to 8 outputs depending on the model used.

The processing delay for all MOD-LA-ALC-X-YYY and MOD-JA-ALC-X-YYY modules is ¼ of a video frame. To
compensate for this processing dela y, the user mu st increase the p rocessing delay o f the card by +1 fram e.
This additional processing delay must be added manually in the Video Output panel under the Timing tab.

5.10 Dolby Metadata panel

This panel provides resources for managing the flow of
Dolby metadata through the XVP-3901. The Dolby
metadata panel is part of the audio processing option (XVP­3901-OPT-AUD).

• Note that unlike the audio processing configuration,
only one (1) Dolby metadata configuration is saved by
the card, regardless of the input format (3G/HD or
SD).

Multiple layers of tabs allow the user to drill down to the
various available controls. For notational purposes, the path
to a particular control panel will be described here as:

[layer 1 tab] → [layer 2 tab] → [layer 3 tab]

For example, the panel shown in the figure on the right
would be described as:

[Path #1] → [Probe 1] → [Dynamic Range]

5.10.1 Path 1 & Path 2 tabs

These two tabs are identical in layout, and will be described together.

• Note that the Generator and Probe are path-specific; i.e. Path #1 has Generator 1 and Probe 1, while Path #2
has Generator 2 and Probe 2.

Input Presence: Status icons are provided to indicate
sources where Dolby Metadata is present and valid. The
following are shown:

• VANC Stream 1

• VANC Stream 2

• RS-422B

• Decoder 1 (grey if not installed)

Note: When decoding PCM audio, the Dolby decoder does not generate any metadata. If a decoder is
selected as a source for a specified metadata path, the generator on the same path will be automatically
turned ON when the decoder is decoding PCM audio. The content of the generator must have been
previously configured. Refer to “Generator automated mode” below for details.

Backup: use this pulldown to select the source that will be used if the primary source becomes
unavailable or invalid. In addition to the available primary sources, the list includes:

• Last valid – return to the last valid source used

• Blank – no metadata output

• Generator – use the interna l generat or

Generator: Use this pulldown to turn the internal generator ON or OFF. Turning it ON selects it
as the source. The generator creates a complete, specific set of metadata, which is configured
in the Generator tab.

Generator automated mode:
The generator is turned on or off automatically in specific conditions to avoid loss of metadata
at the output stream. There are two specific conditions which will trigger the automation behaviors:

1. When a Dolby decoder module is installed and selected as the metadata source of a path, the audio
metadata from a Dolby E input stream will be decoded and passed. When the decoder is fed with PCM audio,
the Dolby decoder will not provide metadat a. Inst ea d, the generator of the selected path will be automatically
turned on. It is the responsibility of the user to configure the generator with the proper PCM metadata
parameters.

2. When an upMAX

tm

module is installed and configured to operate in Follow Metadata mode, the resulting

upMAX

tm

mode is dictated by the coding mode parameter of the probed metadata stream. When the

metadata stream coding mode is 2/0, the upMAX

tm

mode is set to Upmix and the generator will be turned on
to generate 5.1 metadata for the upmixed audio content. It is the responsibility of the user to configure the
generator with the proper 5.1 metadata parameters. If the metadata stream coding mode is 3/2, the upMAX

tm

mode is set to Pass and the generator will be turned off to let the input metadata stream go through. If the
coding mode detected is other than 2/0 or 3/2 or there is no metadata, the reversion mode is used. In that
case, the generator will be turned on for the Upmix and AutoMAX reversion modes, and off for Pass reversion
mode. The generator affected is tied to the module’s socket (i.e. generator on path 1 for upMAX

tm

in socket 1;

generator on path 2 for upMAX

tm

in socket 2).

Notes:

• If the two conditions are true, the upMAX

tm

automation has precedence over the decoder because the

upMAX

tm

is located after the decoder in the audio processing path.

• No automation is provided for the generator content. The generator content is always under user control

and must have been previously configured if used in these conditions.

Hold: Use the pulldown to select Hold ON or OFF.

• ON – freezes the Metadata values used in the output bitstream

• OFF - allows the current metadata to pass to the output

processing, like watermarking, is applied to the audio signal
outside the XVP-3901. The delayed Metadata bitstream will
stay properly timed with its associated audio signal.

5.10.1.4 [Path #1] → [Presets]

Because there are many parameters to set for the generator, it is convenient to be able to save a configuration for
easy recall. The Presets tab offers several convenient functions for this purpose.

The XVP-3901 allows the user to save 10 configurations. These are labeled METADATA 1 to METADATA 10 by
default, but the user can edit the names via the Edit Presets Labels… button at the bottom of the tab.

In addition, the XVP-3901 is preloaded with two fixed data sets named Factory 2.0 and Factory 5.1.
The Current Generator Preset databox at the top of

the tab reports the current preset in use. If all
parameter values do not match the preset values,
the box will show “Custom”.

The Generator Presets pulldown gives access to all
12 available presets. The two buttons to the right
then allow two options:

• Load – load the generator with the values
stored in the preset, overwriting the current
settings

• Save – overwrite the values stored in the
preset with the values currently set on the
card (only for the ten user-settable presets –
the Factory presets cannot be changed).

The Save Probe To pulldown gives access to the 10
user-settable presets. Once one is selected, clicking
on the Save button saves the values detected by the
probe into the user presets, in effect setting the
preset to match the current program stream.

Note – If you attempt to save the card configuration to a User Preset when the Metadata generator settings do not

correspond to a Metadata Preset value ( i.e. if the Curr ent Gener ator Pres et dat a box shows “Cus tom”), you will
trigger a warning because of the way the Metadata Generator settings are saved. See page 92 for a complete
explanation. You may need to return to this panel and save the “custom” settings into a Metadata preset before you
can save the card configuration to a User Preset.

• Avoid this by getting in the habit of saving the Generator Metadata settings each time you change them.

The Metadata Profiles… button gives access to a panel that allows the user to copy the card settings from this XVP­3901 to other XVP-3901 cards accessible via iControl. These profiles are also compatible with the DAP-1781
metadata profiles.

Figure 5.66 Metadata Profile Copy window

The Copy profile from line shows the current XVP-3901 card.

• The Profiles column contains a pulldown that lists the profiles that are available to copy.

• The list includes the two generators, plus the 10 metadata presets

You can save the selected profile to disk for future recall:

• Click the Save profile to disk… button and select a disk location and file name to save the file.

You can recall a previously-saved profile from disk and load it into the card:

• Click the Restore profile from disk… button and find the appropriate file

• Click Open to load the contents of the file into the current XVP-3901

The Copy profile to area shows all other XVP-3901 cards that have been detected on the iControl network.

5.10.2 Input/Output tab

This tab provides resources to configure the input and output selections and processing of metadata for the XVP-3901
card.

VANC Metadata Extractor

The card can extract 2 Dolby metadata streams from the
VANC interval according to the specified SDID (range = 01 to

09). The presence of each stream is reported in the interface.

VANC Metadata Inserter

The card can insert 2 metadata streams in the VANC interval
for each output (3G/HD and SD outputs). Use the four sets of
pulldowns to configure metadata insertion in VANC Stream 1
and VANC Stream 2 for your outputs.

Insertion: Select the source of metadata to insert

• Off: No metadata is inserted.

• Path 1: Metadata from Path 1 is inserted

• Path 2: Metadata from Path 2 is inserted

• ABUS A1: Metadata from the ABUS A1 card is

inserted

• ABUS A2: Metadata from the ABUS A2 card is
inserted

Insertion Line: Select the VANC line in which the metadata
will be inserted. The range depends on the output format:

• 3G/HD: lines 9 to 20

• SD (525) lines 12 to 19

• SD (625) lines 8 to 22

SDID: Select the VANC metadata packet SDID to be
inserted. The SDID is used to specify the relationship
between the VANC metadata stream and the first
channel of its associated audio program.

Note: If the card is configured to insert a special SDID
at the output, any Dolby Metadata packets at the
input with the same SDID will be deleted. Any other
SDID packets not inserted by the card will be passed
through untouched.

5.11 ALC panel

Minimizing loudness differences between
segments in a playout channel is an
important issue in a world where multiple
programs originating in different formats
from different sources must be integrated
seamlessly. The Automatic Loudness
Control (ALC) option is the solution to this
need. It uses Miranda’s proprietary
wideband ALC algorithm.

• Identified as XVP-3901-OPT-ALC-X, where X can be 2, 4, 6, 8 or 16 input channels. The table shows the ALC
models available, and the number and type of programs supported to occupy the available channels:

Model Description Program types supported

XVP-3901-OPT-ALC-2

2-Channel ALC, up to 2 independent programs Mono, 2.0

XVP-3901-OPT-ALC-6

6-Channel ALC, up to 6 independent programs Mono, 2.0, 3.0, 4.0, 5.1

XVP-3901-OPT-ALC-8

8-Channel ALC, up to 8 independent programs Mono, 2.0, 3.0, 4.0, 5.1, 7.1

XVP-3901-OPT-ALC-16

16-Channel ALC, up to 8 independent programs Mono, 2.0, 3.0, 4.0, 5.1, 7.1

GUIDE TO INSTALLATION AND OPERATION

80 | XVP-3901

Note: The ALC works with PCM audio. If non-PCM audio like
Dolby -E or AC-3 is fed to the module, it will be ignored and
all the program channels will be bypassed to prevent
interference with the other PCM audio channels.

5.11.1 Config tab

Channels per program

Pull-downs are available to select the number of channels
per program. Depending on the ALC model, you may have
different possible selections, from 1 to 8 channels per
program.

Input channels selection

An input shuffler allows any combination of the available
channels to be used as inputs to each ALC program.

Note: An input chann el can not be assigned to m or e than o ne
program, and can only be used once within a program.

Global Config

The Mode pull-down selects preset values for target, sliding
window and loudness units that apply to loudness monitoring
for all programs on this XVP-3901:

Mode Target

Short-Term

Time Window

Loudness

Unit

EBU R128 -23 3 sec LUFS
A85 ITU BS.1770 -24 10 sec LKFS
ARIB TR-B32 -24 3 sec LKFS

Enable Loudness Monitoring turns ON the ALC input and output loudness monitoring for all programs.

5.11.2 PGM1-8 tabs

Loudness monitoring

When turned ON, the loudness meters display the program input loudness (before ALC process ing), the d yna mic
correction applied by the ALC, the ALC limiter correction, and the program output loudness (after ALC processing).

The input and output loudnesses are given in LUFS or LKFS, depending on the Mode selected in the Config tab.
Loudness meters are integrated over a “ s lidi ng win do w” period which is also mode dependent.

Dynamic and limiter corrections are always given in dB. Each correction meter is integrated over a period of 250
milliseconds.

ALC Presets

Three factory presets for the ALC are availab le to cover most broadcast applications.

Figure 5.68 ALC panel – Config tab

GUIDE TO INSTALLATION AND OPERATION

XVP-3901 | 81

• Factory Light – The ALC appli es low dynamic range
compression on the audio program content. The overall
response time is relatively slow, which reduces the ALC
ability to tightly follow the target output loudness. Using
this preset, the program content will sound a little more
dense, while keeping most of the original program
dynamic range.

• Factory Standard – The ALC applies moderate dynamic
range compression on the audio program content. The
overall response time is also moderate, which allows the
ALC to follow the target output loudness quite well. This
preset is well-suited for most types of audio content. It is
the factory preset loaded when loadi ng the card default
parameters.

• Factory Heavy – The ALC applies high dynamic range
compression on the audio program content. The overall
response time is relatively fast, which improves the ALC
ability to tightly follow the target output loudness. Using
this preset, the program output content will sound much
more dense, less dynamic.

5 user presets are also available to save and load custom
configurations of the ALC. These presets are labeled ALC 1 to
5 but the user can edit the preset names via the “Edit Labels” button.

We STRONGLY recommend starting with the ALC factory preset (Light, Standard, Heavy) that is closest to the
desired objective, then fine tuning it to reach the desired goal. This will minimize the troubles that will likely be
encountered as many adjustments interact.

ALC Bypass

Checking this box bypasses the ALC program processing, and the input channels pass-through the output unaltered.

Target Loudness

The Output Target pulldown sets the target output loudness. This value sets the average output loudnes s . Due to the
program dynamics, the actual output loudnes s w ill m ove aroun d the sel ec ted targ et . The units of measurement and
the nominal value, as well as the window size for the measurements (not shown on this panel) are set by the Mode
pulldown in the Config tab.

Although the nominal Target Loudness is reset according to the table above when the Mode is changed, the user may
change the value at any time using the pulldown, where the available range is -10 to -31 for all modes.

Here’s the time-domain response of the ALC:

Figure 5.69 ALC panel – PGM 1, 2, 3 ,…. or 8 tab

GUIDE TO INSTALLATION AND OPERATION

82 | XVP-3901

ALC Pre-Amp Level

A pre-amp stage is available in front of the ALC to compensate for programs having an input loudness out of the ALC
tracking range (ver y low or very high in put loudnes s ) . The pre-amp level ranges from -20 dB to + 20 dB, in steps of 1
dB.

Fast Mode Response

The Fast Mode Response is optional and is enabled by checking the Enable box.
The ALC Fast Mode Response kicks in whenever the input loudness goes over the Fast Mode Threshold and

loudness is reduced at the rate set in the Speed pull-down (slow = 100 ms; fast = 25 ms). The Fast Mode Threshold
is given in dB with respect to the target loudness and ranges from 2 to 12 dB, in dB steps.

Transient Mode Response

The Transient Mode Response is optional and is enabled by checking the Enable box.
The ALC Transient Mode Response kick s in whenever the input loudness goes over or under the Transient Mode

Threshold. The Transient Mode Threshold is symmetric with respect to the target loudness and ranges from 2 to 12
dB, in dB steps. When the input loudness is over the Transient Mode Threshold, loudness is reduced following the
rate set by the Speed pull-down. When the input loudness is under the Transient Mode Threshold, loudness is
increased, again following the Speed pull-down, which ranges from Slow (up to 15 seconds) to Fast (up to 4
seconds).

Response Time

Outside of the Fast and Transient modes ranges, the ALC performs loudness correction slowly, following the
Response Time. Response time values are : 5 sec, 10 sec, 15 sec, 20 sec, 30 sec, 45 sec, 1 min, 5 min, 10 min, 15
min, 20 min.

Freeze Threshold

The Freeze Threshold sets the threshold below which the ALC will not increase loudness. This prevents quiet
portions of programs (and noise) from being unintentionally boosted. If the input program loudness is under the
Freeze Threshold for more than 30 seconds, the ALC will smoothly return to 0 dB of loudness correction.

GUIDE TO INSTALLATION AND OPERATION

XVP-3901 | 83

Limiter Threshold

The Limiter Threshold will limit the output loudness under the selected threshold. This prevents loud portions of
programs from being unintentionally clipped. If the input program loudness is over the Limiter Threshold, the ALC
will reduce the loudness very quickly, in 1 millisecond.

5.12 Loudness Panel

Note: In order to use the loudness measurement capabilities of the XVP-3901, the Loudness Option must be
installed. See Loudn es s Meas urem ent opt ion: on page 103 for details.

The XVP-3901 allows the user to measure the loudness of audio streams passing through it. The measurement
process is flexible:

• All major loudness standards are supported.

• The measurement standards can be customized if desired.

• Up to four programs can be measured at once.

• Each program can be selected from an internal XVP-3901 metadata path, or defined manually.

• Segment markers can be inserted from a variety of triggers.

• Log files of the measurements can be stored externally, for analysis using Miranda’s Audio Loudness Analyzer.

User Presets section

The XVP-3901 has memory registers which can hold up to 5 user-defined param eter settings.
The Current Preset box (at the bottom left corner of the panel) displays the last loaded preset. Any change to the card

configuration after a preset is loaded will change the display to "Custom" instead of the preset number.
Select any one of the five pres ets using the pull-down list. The name of the currently-selected User Preset is shown

on the pulldown box.
Click Load to load the contents of the selected User Preset into the XVP-3901. All parameter settings and values will

be replaced by the contents of the selected User Preset.

• The first 4 user presets can be recalled by GPI User Preset 1 to 4, as configured in the GPI tab.

Click Save to store the current parameter settings and values from the XVP-3901 into the selected User Preset. The
existing contents of the preset will be overwritten.

Note: if you see a pop-up warning box like this when you click Save, you will need to decide how to deal with the
Metadata Generator presets. Click on the Metadata FAQ button to learn more about this issue.

Briefly explained, a User Preset stores all the parameter values on the XVP-3901 card except the param eter
values for the Metadata generators. These values are stored in a separate set of registers, and the User Preset
saves the contents of these registers plus a pointer to the register that was most recently used. If you change any
of the Metadata values but do not update the Metadata register by saving it, the values referenced by the pointer
are not the current values. If you save to a user preset under this circumstance, the User Preset will not contain
the changed values, and they cannot be recovered if you later load the card from the preset.

The User Preset Save Alert panel will be triggered any time you attempt to save when the Generator Metadata
values have been changed but not saved. You can tell when this is the case, as both the User Preset box on the
main panel, and the Current Generator Preset box in the Presets tab, as well as the Generator tab label, will all
read Custom

How to tell when the metadata generator settings have not bee n saved

GUIDE TO INSTALLATION AND OPERATION

XVP-3901 | 93

The warning box gives you three options for dealing with the situation:

• Option 1 – abort the save process, so that you can go back and manually save the metadata parameters
(see instructions on page 76)

• Option 2 – go ahead and save anyway, but be aware that if you recall this User Preset you will probably not
restore the current metadata generator settings

• Option 3 – Save the Metadata presets first, in the Metadata register whose name is displayed (it will be last
register that was used, and if it is one of the factory registers a Save will not be allowed, so you might want to
consider option 1), and then save the User Preset.

Use the radio buttons to select one of these options (option 1 is the default), and click OK to proceed.

Lock Input Selection section

When User Presets are saved, the input selection is saved as well. This means that changing User Preset may
change input selection, depending on which one is associated with the User Preset. This is the normal behavior when
”Update Input Select with User Preset” is chosen.

Selecting “Do Not Change I nput Se lect with Us er Pres et” forces the input selection to remain unchanged, while
applying all other settings associated with the selected preset.

5.18.2 Edit Presets Label…

Click this button to open a window where you can define the name assigned to each user preset. This is the name
that will appear on the pulldown in the User Presets section. The labels will also be copied from card to card when a
copy profile is performed.

5.18.3 Profiles…

Use Profiles to save or recover the entire card configuration (including user presets if desired) on an external disk, or
to copy it to another XVP-3901 card.

Click on Profiles to open the Profile Copy window.

and will be difficult to find and identify if not clearly named and conveniently located.

• Click the save button once the name and location have
been identified in the Save box

• If the file is saved correctly, the Transfer Status box on
the right of the Copy profile from line will indicate
Succeeded against a green background
