Description
Ch7/8 delay data. Designates the accumulated
audio processing delay relative to video for audio
channels 7 and 8.
Ch5-8 reserve words. Designates the value set in
the RSRV words of the audio control packet for
audio channels 5 to 8, as per SMPTE 299M.
Not used.
Ch1-4 audio control packet demultiplex enable.
When set HIGH, the audio control packets in the
Luma channel of the video data stream for audio
channels 1 to 4 will be demultiplexed.
Ch1-4 audio control packet DID setting. Designates
the audio control packet DID for audio channels 1 to
4. See
group 1.
Ch1-4 audio frame number. Designates the audio
frame number for audio channels 1 to 4.
Ch1-4 sampling frequency. Designates the audio
sampling frequency for audio channels 1 to 4, taken
from the RATE word of the audio control packet as
defined in SMPTE 299M.
Ch1-4 synchronization. When set HIGH, the "asx"
bit of the audio control packet RATE word
designates audio channels 1 to 4 as asynchronous,
as per SMPTE 299M. When set LOW, the "asx" bit
of the audio control packet RATE word designates
synchronous audio.
Ch1/2 delay data. Designates the accumulated
audio processing delay relative to video for audio
channels 1 and 2.
Ch3/4 delay data. Designates the accumulated
audio processing delay relative to video for audio
channels 3 and 4.
Ch1-4 reserve words. Designates the value set in
the RSRV words of the audio control packet for
