Ch5-8 synchronization. When set HIGH, the "asx" bit
Audio group 4 control packet detect. When set
HIGH, audio control packets with group 4 DID have
been detected in the incoming Luma video
data stream.
Audio group 3 control packet detect. When set
HIGH, audio control packets with group 3 DID have
been detected in the incoming Luma video
data stream.
Audio group 2 control packet detect. When set
HIGH, audio control packets with group 2 DID have
been detected in the incoming Luma video
data stream.
Audio group 1 control packet detect. When set
HIGH, audio control packets with group 1 DID have
been detected in the incoming Luma video
data stream.
Not used.
Ch5-8 audio control packet demultiplex enable.
When set HIGH, the audio control packets in the
Luma channel of the video data stream for audio
channels 5 to 8 will be demultiplexed.
Ch5-8 audio control packet DID setting. Designates
the audio control packet DID for audio channels 5
to 8. See Table 13. The default setting is audio
group 2.
Ch5-8 audio frame number. Designates the audio
frame number for audio channels 5 to 8.
Ch5-8 sampling frequency. Designates the audio
sampling frequency for audio channels 5 to 8, taken
from the RATE word of the audio control packet as
defined in SMPTE 299M.
of the audio control packet RATE word designates
audio channels 5 to 8 as asynchronous, as per
SMPTE 299M. When set LOW, the "asx" bit of the
audio control packet RATE word designates
synchronous audio.
Ch5/6 delay data. Designates the accumulated
audio processing delay relative to video for audio
channels 5 and 6.
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.
