Specifications
The frame phase relationship between the SDI video stream and the analog
reference signal is established according to SMPTE RP 168-2002. This
defines the SDI video frame start occurring N pixel periods before the
frame start of the analog video reference signal. N is defined for each video
format in
In Minimum Delay mode, the UDX module is calibrated to give one frame
of delay through the frame sync portion when the User-Programmable
Delay is zero. The remaining delay through the module is about one
input-video frame. The delay numbers indicate the following:
For Genlock Mode: table entries indicate the delay in output video frame
start from the genlock reference frame start when the input video is exactly
aligned with that reference.
For Input-Timed Mode: table entries indicate the delay in output video
frame start from the input video frame start position.
