1 Product overview

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

1.1 Product description

The Flashlink UDC-HD-XMUX4 is a format converter converting between all HD and SD
formats of the same frame rate. It can synchronize the outgoing HD-SDI or SD-SDI to a
reference, and the reference can either be a traditional black & burst signal or tri-level sync.
The HD-SDI/SD-SDI outputs can be adjusted relative to the sync signal. All product variants
also have a de-glitcher to give error-free synchronous switching.

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 they are embedded back into the
SDI stream.

The parameters of the card can be adjusted either manually by switches on the board, or via
the control interface MULTICON GYDA.

1.4 Differences between the product variants

The UDC-HD-XMUX4(-R(-L)) is the full featured product, the up-/down-/cross-scaler. There
is nothing that can be done with the lesser versions of the module that can‟t be done with the
UDC-HD-XMUX4(-R(-L)).

The UPC-HD-XMUX4(-R(-L)) is an up-scaler only. The only differences from the full featured
product is that the UPC-HD-XMUX4(-R(-L)) is unable to lock onto HD-SDI inputs, and that no
SD-SDI formats can be selected as output.

The CRC-HD-XMUX4(-R(-L)) is an HD cross-scaler only. The only differences from the full
featured product is that the CRC-HD-XMUX4(-R(-L)) is unable to lock onto SD-SDI inputs,
and that no SD-SDI formats can be selected as output.

The UDC-HD-XMUX4(-R(-L)) is thus the only variant of this module that can do aspect ratio
conversions with SD-SDI as both input and output. The lower-cost versions of this module
are complemented by the ARC-SD-DMUX and the ARC-SD-XMUX4, which are both
dedicated SD-SDI aspect ratio converters available in several variants.

3 Configuration

The board can be configured either manually or through the Network control system Multicon
GYDA. Only a subset of the configurable parameters is available when operating in manual

mode.

3.1 Manual mode

To reach manual mode, the DIP16 labeled OVR on the board must be switched on (to the
right) and the board must be re-booted. This takes the board out of Multicon GYDA control (if
it was previously set to off) and into DIP switches and rotary switch control. Settings not
affected by any of these switches are kept unchanged from previous session (factory default
or Multicon GYDA setup).

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. The slide switch in
the lower right in Figure 2 below selects the source for the sync input (backplane or frame
distributed). No software override exists for this switch, it is active in both modes of
operation.

Figure 2: The figure shows a top view component printout of the board.

3.1.1 Rotary switch and push buttons

The rotary switch, labeled DLY, adjusts the phase delay from -5 to +4 video lines. It is only
functional when a sync signal, black & burst or tri-level, is present at the selected sync input.
The rotary switch is accessible from the card front.

The push buttons, labeled INC and DEC, are used to fine adjust the phase delay one sample
at a time. It can adjust within +/- ½ video lines for the present video standard. Pressing both
buttons simultaneously will reset the number of samples to 0.

3.1.2 Factory reset function

The factory reset puts the card back to its initial settings at delivery. These settings are just a
start condition for the board, and new settings applied by the user will still take effect and be
stored.

The factory reset is initiated by setting the DIPs marked F-RESET and OVR to the ON
position and booting the card. The card will display an orange status LED, while all the other
LEDs are dark. The card should then be booted again with the F-RESET DIP returned to the
OFF position. The card will then complete the internal reset and start as normal.

conversion

On: Aspect ratio is forced to
14:9 if converting from HD to
SD or SD to HD.
Off: Aspect ratio is handled by
AFD / VI / WSS / SMPTE352.

If on, AFD/ VI/ SMPTE
control is turned off.
If off, Aspect ratio is
handled by AFD, VI, WSS
or SMPTE352. If no such
information exists, the card
assumes input and output
have the same AR
environment.

3.1.3 DIP switch functions

DIP switch of the vertical DIP package is number 17.

3.2 Multicon GYDA mode

All functions of the card can be controlled through the Multicon GYDA control system. The
Multicon GYDA has an information page and a configuration page.

3.2.1 Information page

nevion.com | 10

Figure 3: Multicon GYDA information page

UDC-HD-XMUX4 Rev. 1

The information page shows a dynamic block-diagram of the board and some additional
informative text. The block diagram updates with the board status, showing input signal
selected and signals missing (by red crosses over signal lines). It also shows the audio
matrix selections that have been made in the configuration page.

Note that if an audio input is not present, the user will still be allowed to select
this input from the matrix, but the output will go to a fallback position. Missing
audio inputs will be shown in the block-diagram as a red cross over the
corresponding matrix input line.

The information text below the dynamic block diagram lists information not easily conveyed
in a graphical manner.

Common scaler settings denote the output format, which is selectable under the same
heading in the Configuration page.

Active scaling: This shows which aspect ratio conversion is currently performed by the card.
Indirectly it also shows why this conversion has been selected: If the text starts with
“Default:” it means that this is the conversion that the user has selected as the default
scaling. This in turn means that the user has either selected the scaling manually,or that no
aspect ratio information was detected in the video to select the proper scaling automatically.
Conversely, of the text starts with “Auto:” it means that the card has valid aspect ratio
information in the form of AFD, VI, WSS or SMPTE352, and that the conversion has been
selected automatically to suit the output environment specified by the user.

Phase delay denotes the time difference in samples between incoming sync source and
outgoing video signal.

The video frame delay represents the actual delay between input and output video.
AES input delay shows the delay (in 48 kHz audio samples) between incoming AES stream

and AES stream going into the cross-point switch. These delay blocks are not shown in the
graphics.

Signal integrity shows the incoming video format and counts errors found on this signal. The
error mask is set up in the Signal integrity block on the configuration page. To reset the
counter to 0, press the Reset button.

DE-embedded datalink gives the status and bitrate of the data de-embedded from an AES
stream. Which AES stream to de-embed data from is selected in the audio cross-point
switch. This datalink is a Nevion proprietary standard and embedding of such data can be
done with the AV/AAV-HD(SD)-XMUX.

3.2.2 Configuration page

The different configuration parameters are explained in detail in Chapter 5, under their
corresponding functions.

Exceptions for the LEDS

The locate command will make all four LEDs blink on and off synchronously. The condition
of the card is not otherwise affected.

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-HD-XMUX4 will automatically reboot after a successful
upgrade.

4.2 GPI alarms
