Frame Sync Function
This function provides for frame sync control using either one of two external
FRAME REF IN (1,2)
input video, or internal timing as a frame sync reference.
This function also allows horizontal and/or vertical offset to be added
between the output video and the frame sync reference.
Frame sync can select from either of two card frame reference sources, or
free-run input video sync. Selectable failover allows alternate reference
selection should the initial reference source become unavailable or invalid. In
the event of input video loss of signal, the output can be set to disable video,
go to black, go to an internal test signal generator pattern, or freeze to the last
intact frame (last frame having valid SAV and EAV codes).
An internal test signal generator provides a selection of various standard
patterns such as color bars, sweep patterns, and other technical patterns. The
test patterns can be applied to the output video upon loss of input or manually
inserted at any time.
