Full-Frame Mode Output Video Delays with respect to Input or Reference Timing Source
Note the following about Full Frame Mode:
In Normal Delay Mode with Input-Timed video and zero user-input delay, the electrical length of the module is two frame peri-
ods of the input video format. Genlock timing of the module produces an electrical length that varies between two and three
frame periods of the input video format. For synchronous input video, the electrical length is a constant value between two and
three frame periods minus 5 line periods. For asynchronous input video the electrical length slowly decreases to two frame
periods minus 5 line periods or increases to three frame periods minus 5 line periods, beyond which it snaps back to the
opposite extreme
Input-timed delays are output video frame start with respect to input video frame start.
Genlock delays are output video frame start with respect to reference signal frame start when the input video is exactly aligned
to that reference signal.
Delay range is shown in whole frames, from N to M, but in all cases the true range limits are N minus 5 lines and M minus 5
lines.
Two delay values are shown for 720p to interlaced conversions when Input-timed because interlaced output field position is
arbitrary in this case.
