Description
Ch1-4 audio group DID setting. Designates the
audio group DID for audio channels 1 to 4.
See
or register) is set LOW, the default setting is
audio group 1. When CASCADE is set HIGH, the
default setting is audio group 3.
Not used.
Ch5-8 audio control packet multiplex enable.
When set HIGH, the audio control packets for
audio channels 5 to 8 will be multiplexed into
the Luma channel of the video data stream.
Ch5-8 audio control packet DID setting.
Designates the audio control packet DID for
audio channels 5 to 8. See
default setting is audio group 2.
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.
