1 Product description

Figure 1: Simplified block diagram of the UDC-3G-XMUX4 card

1.1 The core functionality

The UDC-3G-XMUX4 is a format and standard converter that can convert between all the
common SD, HD and 3G level A video standards. As part of the conversion, the aspect ratio,
the crop, or the position of the output picture can also be altered. This process can be fully
automated by AFD, WSS, WSS-EXT, or VI in combination with 12 built-in conversions, or the
user can take full manual control by selecting between 12 built-in conversions and 12 fully
configurable custom conversions.

Motion adaptive de-interlacing is used to ensure optimal picture quality.
The UDC-3G-XMUX4 comes in the standard Flashlink form factor and it is designed to be

used with Multicon Gyda, the Nevion system controller. A subset of the configuration
parameters can also be controlled by onboard switches, enabling stand-alone operation.

1.2 Secondary functionality

1.2.1 Standard conversion

The UDC-3G-XMUX4 can be used for standard conversion, i.e. conversion between 50 Hz
and 60 Hz / 59.94 Hz time bases. The motion adaptive de-interlacing ensures a remarkably
artefact-free output for this class of converter.

1.2.2 Frame synchronizer

The UDC-3G-XMUX4 has a built-in frame synchronizer. It can synchronize the SDI output to
a traditional black & burst reference or to a tri-level sync reference. The SDI output can be
phase adjusted relative to the sync signal. No additional frame delay is available for the
UDC-3G-XMUX4.

1.2.3 De-glitcher

The UDC-3G-XMUX4 comes with a built-in de-glitcher for continuous and seamless output.
This will clean up line errors due to up-stream switching or other signal glitches. The output
even remains error-free with change of input formats.

nevion.com | 5

UDC-3G-XMUX4+ Rev. C

1.2.4 Audio embedder/de-embedder with audio matrix and processing

The UDC-3G-XMUX4 comes with full embedder/de-embedder capabilities. The audio
embedded on the SDI is de-embedded and can be delayed relative to the video. Each audio
stereo pair can be swapped in a matrix before being embedded back into the SDI stream.

1.2.5 Four AES I/O ports

The UDC-3G-XMUX4 comes with four bidirectional AES ports. Bidirectional means that each
port can be configured to be either an input or an output. The direction can be set
independently for each of the four ports and they will then work as inputs or outputs to the
audio matrix. The AES I/O ports are an optional feature.

1.2.6 Audio delay lines

Each AES port comes with its own delay line, which means that the audio can be given a
(positive or negative) delay relative to the video. A common delay setting is also provided for
the eight embedded channels. The delay lines make it easy to pre-compensate for the delays
incurred by external audio processors such as Dolby E.

1.2.7 Closed Caption CEA708/CEA608 and time code support

The UDC-3G-XMUX4 will transport closed caption and time code packages between input
video standard and the output video standard. In the process it will convert and transform the
packages as necessary to confirm to the output video standard.

1.2.8 Input change-over with fallback to internal generators

The UDC-3G-XMUX4 comes with an electrical SDI input and an additional (optional) optical
input. Sophisticated input selection logic can switch between the physical input when a signal
is available, and also switch to one of several internal video generators in the event that no
physical input is present.

1.2.9 Multiple SDI outputs

The UDC-3G-XMUX4 comes with four BNC SDI outputs organized as two pairs of
inverting/non-inverting outputs. Each pair of outputs can be taken from the processed video
output, or directly from the input (reclocked only) for monitoring purposes.

1.2.10 In-monitor label inserter

The UDC-3G-XMUX4 comes with a built-in label-inserter that can be used to add a
identifying text string in active video, either permanently or only when the module has lost its
expected input and has reverted to a fallback generator.

1.2.11 Long-haul optical input

The UDC-3G-XMUX4 can be equipped with an optional 9/125µm single mode optical input
for long-haul applications.

1.2.12 Video processing

The UDC-3G-XMUX4 comes with luma/chroma gain and level adjustment and spatial low­pass filters. The low-pass filters can be a useful tool to control the bandwidth of the input to
video compression equipment.

1.2.13 EDH processing

The UDC-3G-XMUX4 always does EDH processing.

1.3 Product variants and how they differ

The base variant of the UDC-3G-XMUX4 comes with a single electrical input. An optional
optical short-haul or long-haul receiver can be added. The short-haul receiver version is
denoted with an –R appended to its name. The long-haul receiver version is denoted with an
–R-L appended to its name.

The base variant of the UDC-3G-XMUX4 does not have the AES I/O ports enabled. AES I/O
capabilities must be ordered as a factory option or purchased as a software key upgrade at a
later time.

The base variant of the UDC-3G-XMUX4 comes without SD/HD/3G input capabilities and
also without SD/HD/3G output capabilities. SD, HD and/or 3G input capabilities must be
ordered as a factory option or purchased as a software key upgrade at a later time. The
same goes for SD, HD and/or 3G output capabilities. This means that if the customer wants
to buy a pure HD-to-3G upscaler, she will only have to buy the HD input capability and the
3G output capability. Naturally, this also means that at least one set of input capabilities and
one set of output capabilities must be added to the ‘naked’ hardware to get a useful module.

The following table summarizes the ordering options available (for prices, please contact
Nevion or an authorized Nevion dealer):

At the bottom of the information page (the ‘front page’) of the module in Multicon GYDA a line
will show which features are enabled:

This example shows a module with all optional features present.

1.3.1 How to apply a software key that enables new options

1) In Multicon Gyda, navigate to the UDC-3G-XMUX4+ module in question by first
pressing the frame symbol and then pressing the icon for the UDC-3G-XMUX4+. In

nevion.com | 7

Table 1: Available options

UDC-3G-XMUX4+ Rev. C

the example picture below, two such modules are present in the same frame, and the
one in slot 1 has been selected.

Figure 2: A frame with two UDC-3G-XMUX4+ modules

2) Check which features are already enabled in the module. At the bottom of the

information page that is now shown will be a line that says “Purchased features”,

which lists the enabled input formats, the output formats, and finally whether the AES
I/O has been enabled or not. In the examples shown here, all optional features are
already enabled and no further upgrades are available.

Figure 3: How to see purchased features, new Multicon Gyda

Older versions of Multicon Gyda cannot display the line “Purchased features”
properly, the words “In:”, “Out:” and “AES” will be missing.

Figure 4: How to see purchased features, older Multicon Gyda

If for instance “3G” should be missing from the input or output lists, or the AES option
says “No”, these features can be purchased as a software key upgrade.

3) If the customer decides to buy a feature upgrade, Nevion will need both the serial
number of the module to be upgraded and a list of the new features the customer
wishes to purchase for it.
The serial number can be found on the very bottom of the configuration page for the
module (To navigate between the information page and the configuration page, press
the “i” symbol and the wrench symbol, respectively).
Each new input format format or output format has its own order number in the price
list, as does the AES I/O option.

Figure 5: Where to find the serial number

4) The customer will receive a software key from Nevion. The key will be in the form of
the string “optn 0” plus six groups of up to 10 digits. Like this, but with different
numbers:

optn 0 1234567890 1234567890 1234567890 1234567890 1234567890 1234567890

UDC-3G-XMUX4+ Rev. C

This software key is linked to the serial number of the module and must be sent to the
module via the debug terminal in Multicon Gyda.

To access the debug terminal, first press “Config” in the top menu, and then press
“Debug terminal”.

Figure 6: First step towards accessing the debug terminal

Figure 7: Second step towards accessing the debug terminal

5) Now comes the only tricky part of the procedure: To address a particular module
through the debug terminal, one has to take the frame number and slot number and
make a unique two-digit address from them. To do this, multiply the frame number
from the Multicon GUI with 10, then add the slot number from the Multicon GUI, and
finally subtract 1.
Another way of saying this is that the left digit of the address is the frame number,
and the right digit is the slot number minus one, i.e. slots counted from 0 to 9, instead
of 1 to 10 as they are displayed in the Multicon user interface.
The two modules in our example were both in frame 0, but in slots 1 and 5
respectively. This gives us the addresses “00” (0*10 + 1 - 1) and “04” (0*10 + 5 - 1).

Before trying to send the software key it could be wise to check that the addressing is
indeed correct. That can be done by sending a single question mark (“?”) to the

module. In the Flashlink protocol this is known as the “hello” command, and is

basically a who-are-you command. The module should identify itself with the module

nevion.com | 9

UDC-3G-XMUX4+ Rev. C

type, version information, and serial number. In the example below the hello
command has been sent to the module in frame 0/slot 5 (that is, address “04”), and
the module has replied. Then the software key “optn 0 123456 123 …” has been
copy-pasted into the command field and is ready to be sent to the module. The
command will be sent when the “Ok” button is pressed. The module will then reply
with “ok”, and restart with the new features enabled. It will take a few seconds before
Multicon Gyda rediscovers the module after the restart.

Figure 8: The debug terminal, ready to send the software key to the module

6) Remember to check that the module now has the new features enabled. Please refer
to step 2).

2 How to get started

2.1 Power requirements

The absolute maximum power consumption for this module is 9.0 W. This does however
include the 0.5 W for the optional PIN or APD optical input modules, and 0.8 W for the AES
I/O option, and also varies considerably with the combination of input and output video
standards used. If the module will always be used with the same combination of input and
output standards, the table below can be used to determine the actual maximum power
consumption, and to determine how many modules can safely be used in one frame.

Note that the module will draw all its power from +5 V. Check the +5 V rating of
the power supply, generally it will be lower than the rating for the entire supply.

Table 2: Maximum power consumption as a function of video standards used

Note that the figures in the table above include 0.5 W for the optional PIN or APD
module, and 0.8 W for the AES I/O option. These numbers can be deducted if the
corresponding option has not been purchased for the module(s) in question.
Even if the AES I/O option has been purchased, ~0.3 W can be deducted from
the table values if all four AES I/Os are used as inputs.

The backplane for the UDC-3G-XMUX4 is labelled UDC-3G-XMUX4-C1. It is designed to be
fitted in a Flashlink rack unit and to take up a single slot. The connection side will face
outward on the back side of the Flashlink rack when mounted correctly. The table below is an
overview of the connectors and their associated functions.

Table 3: Connector functions

Unused SDI inputs/outputs should be terminated with 75 Ohm.

2.2.1 Sync input

The main module features a slide switch to select between sync taken from the backplane

input (switch position marked “BP”) and a frame-distributed sync (switch position marked
“RACK”). At the time of writing this manual no frame-distributed sync is available, and the

switch should be kept in the “BP” position.
The backplane also features a switch on the component side (the side facing into the frame).

This is a switchable termination for the backplane sync input. By setting the slide switch in
Figure 9 to the “ON” position, the sync input will be terminated to 75 Ohm. Generally, the
sync inputs should be terminated if each sync input is fed from a separate output of a
distribution amplifier. If one sync output is passively split and fed to several modules
(T-connectors) one module should be terminated while the others should be left
unterminated.

If the module will be used without a frequency reference the positions of these slide switches
do not matter.

2.2.2 GPI outputs (alarms)

The UDC-3G-XMUX4 has one GPI output. This reflects the general status of the card, and
thereby acts as an all-purpose alarm. See Table 4 below.

2.2.3 GPI inputs

The UDC-3G-XMUX4 has four GPI inputs. Together they form a four-bit number (16
combinations) that can be used to select one of the many conversions that the module can
perform., either as the fallback conversion for when the automatic logic lacks the necessary
input information to make a decision, or a completely manually selected conversion. This is
the subject of chapter 3.6, and section 3.6.7 in particular. See Table 4 below for the location
of the GPI inputs.

2.2.4 Data link output lines

The UDC-3G-XMUX4 has one pair of data output lines. Together they form an RS422 output.
The data is de-embedded from one of the embedded audio channels. These data must of
course have been embedded by another module upstream. See Table 4 below for the pin­out.

2.3 What the LEDs mean

nevion.com | 13

Table 5: LED states and what they mean

UDC-3G-XMUX4+ Rev. C

2.3.1 Exceptions/special conditions for the LEDS

The locate command will make all four LEDs blink on and off synchronously to quickly
identify the module in a larger installation. The condition of the card is not otherwise affected
by the command, only the appearance of the LEDs will change. The LEDs will return to their
normal states and functions after the special locate condition times out.

FPGA firmware upgrades will activate running lights after the firmware download has
finished. Do not remove power to the card when running lights are active, the card is
unpacking and installing the new firmware. The UDC-3G-XMUX4 will automatically reboot
after a successful upgrade, and the LEDs will then also return to their normal functions.

2.4 Selecting between Gyda mode or Manual mode

The board can be configured either manually or through the system controller Multicon
GYDA. Since there’s a limited number of switches available compared to the total number of

settings available for the module, only a subset of the parameters can be adjusted when
operating in manual mode. Generally, the parameters that cannot be directly controlled by
the DIP switches will take their settings from the previous Multicon GYDA session. This
means that for a specific manual setup it may be necessary to configure the module with a
Multicon GYDA before switching to manual mode.

To reach manual mode, the lower DIP (labelled OVR) on the module must be switched to the
“On” position (to the right) and the board must be re-booted. This isolates the board from
Multicon GYDA control, but the module will still accept commands to retrieve its status, and
also the commands necessary to initiate and perform firmware upgrades.

In addition to the DIP switches, manual mode will also activate the rotary switch and the two
push-buttons at the front of the module. These are used to control the phase delay for the
built-in frame-synchronizer, see chapter 3.1.1.

2.5 The very brief guide to Manual mode set-up

More details and possibilities are described in chapter 3.1, entitled ‘Detailed control in
manual mode’. This is just the bare minimum to get started and get a useful output in Manual
mode:

2.6 The very brief guide to Gyda mode set-up

All of these settings are covered in much more detail in chapter 3.2. These are just the most
important settings to get started:

Arguably the most important setting is where to take the input from. If the module was
purchased with the electrical input only, this would be a good starting point:

What this means is that the electrical input will be chosen whenever a signal is present, and
if a signal is not present, the output will frame freeze for 500 ms before resorting to an
internal fallback generator. Here this generator is set to produce just black video frames.

If the module was purchased with the optical input option, the setup could either be like
above, or with the Optical input instead of the Electrical input, or one input could serve as a
backup for the other, with a final fallback to generator, as illustrated below:

Then it is time to worry about the output. The output format is set like this:

If the output is HD or 3G, the Output environment should be set to Always 16:9. If the output
is SD, this setting will depend on whether the output is intended to be best viewed on a 4:3
monitor or a 16:9 monitor. If in doubt, try both and see the difference.

Generally, the Rule should be left in the AFD->Non-AFD->Default position, as that will
always give the correct conversion based on the embedded information about the picture
content. If the user instead wants to have total manual control over the conversion, the rule
should be set to Default:

The actual selection of conversion will then be come directly from the drop-down menu called
Default scaling, at the bottom of the group of settings above. This setting can also be
controlled from the four GPI input lines, which together give 16 combinations, each of which
can be mapped to a conversion in the matrix that looks like this:

The combination 0000 should usually be mapped to No action, which means that if no GPI
control is present, the GPI lines will not affect anything.

If the module was purchased with the AES I/O option, the direction of each AES port can be
set, see the bottom half of the illustration below. These outputs can be taken from incoming
embedded audio, or from AES ports that are set as inputs. If any of ports are set as inputs,
these inputs can of course also be selected as sources for the re-embedded audio channels.
The audio routing is all handled by the audio matrix in the upper half of this illustration:

2.7 How to get back to factory defaults?

To access the function that will reset the module and reload the factory default settings, the
module must briefly be put into manual mode. The entire procedure is described in chapter

3.1.3.

3 Detailed control

3.1 Detailed control in manual mode

To reach manual mode, the lower DIP (labelled OVR) on the module must be switched to the
“On” position (to the right) and the board must be re-booted. This isolates the board from
Multicon GYDA control, but the module will still accept commands to retrieve its status, and
also commands related to initiate and perform firmware upgrades.

The Manual Mode configuration controls are all found on the front side of the board. There
are three sets of DIP switches, one rotary switch, and two push buttons.

Figure 11: The figure shows a top view component printout of the board.

3.1.1 Rotary switch and push buttons

The rotary switch and the push buttons are used to control the phase delay setting of the
frame-synchronizer. They are accessible from the front of the module and are meant to be
adjusted when the module is powered and active. No change will be seen in output video
unless a sync input (black & burst or tri-level) is present.

The rotary switch, labelled DLY, adjusts the phase delay from -5 to +4 video lines.
The push buttons, labelled INC and DEC, are used to fine adjust the phase delay one

sample at a time. They can adjust the additional samples setting within +/- ½ video lines for
the present video standard. Pressing both buttons simultaneously will reset the number of
additional samples to 0. Holding one of the buttons in will accelerate the increase/decrease
action until the button is released (or one of the limits -½ or +½ video lines is reached). When
the samples setting is reset or one of the limits reached, this will be acknowledged with a
series of short flashes on the LED(s) closest to the activated button(s).

3.1.2 DIP switch functions

The two horizontally mounted DIP switch packages are here denoted DIP1­DIP16, counted from left to right. The vertically mounted DIP package is denoted
with DIP17-DIP24, counted from top to bottom.
