Chapter 3: Operation
To maintain an alignment between video and audio in PCM mode, set the
Audio/Video Align
parameter (Processing > Video > Delay) to
Yes
. This
introduces a matching video delay and maintains audio/video alignment.
When using Non-PCM Audio, or when sample rate converters are bypassed, set
the
Audio/Video Align
parameter (Processing > Video > Delay) to
No
to avoid
excessive video delay.
AFD/WSS/VI Detection and Insertion
AFD, WSS (625 only), and VI (526/625 only)
embedded video metadata
specify the active area to be displayed from a video input. These codes do not
do any aspect ratio conversion themselves, but indicate how the video should
appear to systems capable of interpreting the data.
•
Seven input parameters (Input > AFD/VI/WSS De-embedder) on
HMX6803
+
modules indicate the presence of AFD, WSS, and VI data
when you determine the lines where this data is likely to appear, if present.
•
The single processing parameter (
Out Aspect Ratio
, which appears at
Processing > Video > AFD/VI/WSS) determines the options for the
AFD
Select
and
VI Select
parameters.
•
Twelve output parameters (Output > AFD/VI/WSS Embedder) determine
the line to embed AFD, WWS, and/or VI codes on, the code(s) to be
embedded, and what happens when a code disappears from the input.
