1 Product overview
Figure 1: Simplified block diagram of the PGM-HD-2X1-PB card
1.1 Product description
The Flashlink PGM-HD-2X1-PB is a 2x1 HD/SD program switch with configurable fadein/fade-out and built-in frame synchronizer. Embedded audio is faded in/out with the
video. The frame synchronizer locks an HD-SDI or SD-SDI input to a black & burst or
tri-level signal, and a de-glitcher ensures an always error-free output.
The user parameters of the card can either be changed by switches on the board, or by
the control interface Gyda.
1.1.1 Product versions
At the time of writing this manual, only one version exists, the PGM-HD-2X1-PB.
1.1.2 Key features
Passive bypass from both inputs to non-inverted outputs with less than 25m loss of
cable length (enables full redundancy)
HD/SD video support (will work with DVB-ASI in through mode, but no fading)
De-glitching of input video signal (always seamless output)
Full manual control over selected input or black via GPI inputs or the system
controller Multicon
User selectable generator pattern as fallback for missing signals
HD/ SD frame sync /delay (8 frames max)
Audio delay, enabling Dolby-E processing delay correction
Embedded audio gain adjustment for each video input
Audio fade out/ fade in at switching or frame-wrap

PGM-HD-2x1-PB Rev. B
3 Configuration
The board can be controlled manually via DIP switches, rotary switches and push
buttons on the board, or through the graphical user interface provided by the system
controller Multicon Gyda. Only the most frequently changed and/or most important
settings are available on the DIP switches. If Multicon is used to do an initial setup of
the other settings, these settings will be retained in the module for future sessions,
even for manual mode.
3.1 Manual mode
To reach manual mode 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 Gyda control (if the
switch was previously set to off) and over to DIP switch, rotary switch and push button
control. This particular DIP switch (and the factory reset DIP switch) will only be read at
start-up. Settings not controlled by any of these manual switches/buttons are kept
unchanged from previous session (factory setup or Gyda setup).
The Manual Mode configuration controls are all found on the front side of the board.
There are two sets of DIP switches, one rotary switch and two push buttons. The slide
switch on the lower right side should be se to the lower position (“BP”) for all operation
modes.
Figure 2: The figure shows a top view component printout of the board. LEDs, push-
buttons, the rotary switch and the 2 sets of DIP-switches are colorized.
3.1.1 Rotary switch and push buttons
The rotary switch, labeled DLY, adjusts the phase delay by -5 to +4 video lines. It is
only functional when a sync signal, black & burst or tri-level, is present at the sync
input. The rotary switch is accessible from the board front.
The push buttons, labeled INC and DEC, are used to fine adjust the phase delay by
samples. It can adjust within +/- ½ video lines for the present video standard.
These settings are part of the frame synchronizer, see chapter Frame synchronizer5.4
for further explanations.
3.1.2 Slide switch
The slide switch on the lower right side of the card switches between backplane sync
input (BP) and Flashlink rack distributed sync (RACK) (Future feature upgrade of
Flashlink frame). Switch moved down routes the backplane sync to the card.

perform a fade-in or fade-out.
The same value will be used for
all four fade timers, all fading will

Additional black frames will not
be modified, i.e. the value from
the previous Multicon GYDA
controlled session will be
preserved. The default is 0

The special condition [On On On]
will not modify the fade timers at
all. This setting can be used to
preserve asymmetric fade
configurations from Multicon
Gyda even in manual mode.

3.1.3 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 done by the user will still take
effect and be stored.
The factory reset is done by setting DIP 15 and 16 to on and power up the card. The
inputs should be removed. Then, pull out the card, put DIP 15 to off and power up the
card again. The card will now reset. The board must be under power for at least 10
seconds for all the factory reset values to be stored for the next session.
3.1.4 DIP switch functions
The two sets of DIP switches are labeled with a number running from 1 to 15. The 16th
DIP is labeled OVR.
Note that the left DIP switch of the horizontal DIP package is number 1.
The top DIP switch of the vertical DIP package is number 9.

3.2 Gyda mode
All functions of the card can be controlled through the Gyda control system. The Gyda
has an information page and a configuration page.
3.2.1 Information page
The information page shows a dynamic block-diagram of the board and some
additional information text. The block diagram updates with the boards status, showing
input signal selected, signals missing (by red crosses over signal lines) and routing
through switches.
The text on the information page gives additional information or information about
functionality not displayed on the dynamic block diagram.

Figure 3: Gyda information page
The Reclocker block shows if the card is currently locked to an input. Possible values
are Locked or Loss of lock.
The Sync source block shows if a valid sync signal is detected on the dedicated sync
input, or if output video is generated with the SDI input as the input as the only
frequency reference. Possible values are Black&Burst, Tri-level, SDI, and Missing
(when no input of any kind is present).
The Phase delay block shows the currently used phase delay, re-calculated to video
samples for the current video standard.
The video delay block shows the actual delay used between input and output video, recalculated to both nanoseconds and to video samples for the current video standard.
Note that although there could be rounding errors in these re-calculations, the delays
will still be exactly as set by the user in the configuration page.
The Signal integrity block shows the current input video standard and a counter of
frames seen with errors. The counter can be reset, but will also restart when it reaches
216 = 65536 errors. The list of error bits shows a snap-shot of the last frame reported to
Multicon, and errors are indicated with a red background color. This is based on the
raw error data; If the user has selected to mask off certain errors, these errors will still
be shown here in the snap-shot, but they will not cause the counter to be increased.
The two relative audio delay blocks show how much embedded audio will de delayed
relative to the video, in 48 kHz audio samples. This delay can be different for the two
video inputs.
