Description
CT [3:0]. Audio coding type.
0x00 = refer to stream header.
0x01 = IEC60958 PCM.
0x02 = AC3.
0x03 = MPEG1 (Layer 1 and Layer 2).
0x04 = MP3 (MPEG1 Layer 3).
0x05 = MPEG2 (multichannel).
0x06 = AAC.
0x07 = DTS.
0x08 = ATRAC.
CC [2:0]. Audio channel count.
000 = refer to stream header.
001 = 2 channels.
010 = 3 channels.
111 = 8 channels.
SF [2:0]. Sampling frequency.
000 = refer to stream header.
001 = 32 kHz.
010 = 44.1 kHz (CD).
011 = 48 kHz.
100 = 88.2 kHz.
101 = 96 kHz.
110 = 176.4 kHz.
111 = 192 kHz.
SS [1:0]. Sample size.
00 = refer to stream header.
01 = 16-bit.
10 = 20-bit.
11 = 24-bit.
Max bit rate (compressed audio only).The value of
this field multiplied by 8 kHz represents the
maximum bit rate.
CA [7:0]. Speaker mapping or placement for up to 8
channels. See Table 33.
DM_INH—down-mix inhibit.
0 = permitted or no information.
1 = prohibited.
LSV [3:0]—level shift values with attenuation
information.
0000 = 0 dB attenuation.
0001 = 1 dB attenuation.
…..
1111 = 15 dB attenuation.
