Click the Sync Format list arrow and then click the format that matches external
sync source that you connected - SDI Sync or Composite.
The software should automatically detect the external sync signal. When it does,
the sync format information appears in the Input Video Format text box.
If the software loses the external sync signal or does not detect it
automatically, click Detect to force detection of the sync signal.
d
If you chose frame lock synchronization, select the signal format you want to use as
described under
Only those modes that are compatible with the detected sync signal will appear in
the SDI signal format list.
Adding a Delay to the Signal
You can introduce a slight delay in the genlocked or frame locked SDI output. For
example, if delivery of video from other equipment is delayed because of greater cable
length, you can introduce a delay in the SDI output from this card so that both deliveries
are in sync. To introduce a synchronization delay:
1
Open the Graphics to Video Out page and click Synchronization Options.
2
In the Synchronization Delay group box, introduce delays in the HSYNC and VSYNC
signals as needed by clicking the appropriate up and down arrows.
You can also enter values directly into the text boxes.
