Force to PSF is available for non-UHD formats.
Set the delay mode of the decoder to match that of the transmitter.
NOTE: The lowest latencies are only available from a Vislink transmitter.
UHD formats set the mode of the video outputs to either quad-split (4 x 3G) or
2SI.
NOTE: When the unit is set to quad split output, the delay is fixed.
Adjust Video PTS and Audio PTS values to correct for A/V delay errors. Set any
Vislink HEVC transmitter values to zero.
