Item
Name
Description
Address Bit
ASXB
Ch5-8 synchronization. When set HIGH, the "asx"
023
0
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.
DEL1-2B[25:0]
Ch5/6 delay data. Designates the accumulated

audio processing delay relative to video for audio
025
7-0
channels 5 and 6.
026
7-0

the RSRV words of the audio control packet for
02D
7-0
audio channels 5 to 8, as per SMPTE 299M.
02E

RSV
Not used.
02F
7-3
CTRONA
Ch1-4 audio control packet demultiplex enable.
02F
2
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.
CTRIDA[1:0]
Ch1-4 audio control packet DID setting.
02F
1-0
Designates the audio control packet DID for
audio channels 1 to 4. See Table 5-24. The default
setting is audio group 1.
AF_NOA[8:0]
Ch1-4 audio frame number. Designates the audio
030
0
frame number for audio channels 1 to 4.
031
7-0
RATEA[2:0]
Ch1-4 sampling frequency. Designates the audio
032
3-1
sampling frequency for audio channels 1 to 4,
taken from the RATE word of the audio control
packet as defined in SMPTE 299M.
ASXA
Ch1-4 synchronization. When set HIGH, the "asx"
032
0
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.
DEL1-2A[25:0]
Ch1/2 delay data. Designates the accumulated
