Frame Delay (ADC-8733A-S only)
The Frame Delay mode is identical to the Line Delay mode, except that the output timing can be
delayed by up to a full frame of video. By using almost a full frame of delay, it is possible to set
apparent negative timing, making it look like the output occurs before the input.
Frame Sync (ADC-8733A-S only)
The Frame Sync mode makes it possible to use asynchronous sources. The output timing is
generated entirely based on the reference. Whether a synchronous or an asynchronous source is
used, output timing is constant. The delay through the card will be:
• one full frame of buffered video;
• an additional delay of anything from the minimum latency of the ADC-8733A-S (an
amount in the order of less than a microsecond) up to an additional full frame of delay
(two frames total).
Up to one extra frame of delay can be added to the output in half-pixel increments in this mode.
