Linux—Using the Graphics to Video Out Control Panel

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:

1Open the Graphics to Video Out page and click Enable SDI Output.

2In 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.
