Description
Ch1-4 audio control packet DID setting.
Designates the audio control packet DID for audio
channels 1 to 4. See
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).
Ch1/2 delay data. Designates the accumulated
audio processing delay relative to video for audio
channels 1 and 2. Will be multiplexed into the
audio control packet as per SMPTE 299M.
Ch3/4 delay data. Designates the accumulated
audio processing delay relative to video for audio
channels 3 and 4. Will be multiplexed into the
audio control packet as per SMPTE 299M.
Ch1-4 reserve words. Designates the value set in
the RSRV words of the audio control packet for
audio channels 1 to 4, as per SMPTE 299M.
NOTE: As these words are reserved for future
use, they should be set to zero.
Arbitrary data packet multiplex. Valid only when
"ARBITMODE" is HIGH. When set HIGH, arbitrary
data packets will be multiplexed into the Luma
video data stream using the Host Interface
register settings.
Arbitrary packet mode select. When set HIGH,
arbitrary data packets are multiplexed using the
Host Interface register settings. When set LOW,
arbitrary data packets are multiplexed using the
external pin inputs.
Arbitrary packet Data ID setting. Designates the 8
LSBs of the arbitrary data packet DID word. The 2
MSBs are internally generated. "ARBITDID[7]" is
the MSB and "ARBITDID[0]" is the LSB. Valid only
when "ARBITMODE" is HIGH.
