The AC-3 encoded signal is
sent to the XVP-1801 via
ABUS.
This card is in Serial mode.
On the video card, set the
Additionnal Frame Delay to 7
frames to match the process &
encode latencies.
The tracking delay is applied on
this audio card. Set the Fixed
Delay, with a negative value, to
compensate the tracking delay:
minus 7 frames.
