Ch5-8 audio frame number. Designates the audio
frame number for audio channels 5 to 8. Will be
multiplexed into the audio control packet as per
SMPTE 299M.
Ch5-8 sampling frequency set. Designates the
audio sampling frequency for audio channels 5 to
8. Will be multiplexed into the RATE word of the
audio control packet as per SMPTE 299M. The
default setting is 48kHz.
Ch5-8 synchronization set. When set HIGH, the
"asx" bit 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
(default setting).
Ch5/6 delay data. Designates the accumulated
audio processing delay relative to video for audio
channels 5 and 6. Will be multiplexed into the
audio control packet as per SMPTE 299M.
Ch7/8 delay data. Designates the accumulated
audio processing delay relative to video for audio
channels 7 and 8. Will be multiplexed into the
audio control packet as per SMPTE 299M.
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.
NOTE: As these words are reserved for future use,
they should be set to zero.
Not used.
Ch1-4 audio control packet multiplex enable.
When set HIGH, the audio control packets for
audio channels 1 to 4 will be multiplexed into the
Luma channel of the video data stream.
Ch1-4 audio control packet DID setting.
Designates the audio control packet DID for audio
channels 1 to 4. See Table 7. The default setting is
audio group 1.
Ch1-4 audio frame number. Designates the audio
frame number for audio channels 5 to 8. Will be
multiplexed into the audio control packet as per
SMPTE 299M.
Ch1-4 sampling frequency set. Designates the
audio sampling frequency for audio channels 1 to
4. Will be multiplexed into the RATE word of the
audio control packet as per SMPTE 299M. The
default setting is 48kHz.
Ch1-4 synchronization set. 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
(default setting).
