STA310
4.6.1.3 Dual Mode
The Dual Mode corresponds to a mode where two completely independent mono program channels (e.g. bilin-
gual) are encoded in the bitstream, referenced to as channel 1 and channel 2.
The possible ways to output channels on left/right outputs are:
This channels downmix is specified in the register DUALMODE.
4.6.2 MPEG
The STA310 is able to decode MPEG-1 layerI and layerII encoded data, as well as MPEG-2 layer I, layer II data
without extension (i.e. 2-channel streams).
The MPEG input format should be specified in the DECODESEL register:
4.6.3 MP3
The STA310 is able to decoder MPEG2 layer III (MP3) data.
The MP3 input format aboved be specified in the DECODESEL register:
4.6.3.1 Dual Mode
The Dual Mode corresponds to a mode where two completely independent mono program channels (e.g. bilin-
gual) are encoded in the 2-channel incoming bitstream, referenced to as channel 1 and channel 2.
The audio decoder allows to:
The output configuration is chosen by special downmix for dual mode through register MPEG_DUAL.
20/90
- Output channel 1 on both L/R outputs,
- Output channel 2 on both L/R outputs,
- Mix channels 1 and 2 to monophonic and output on both L/R,
- Output channel 1 on Left output, and channel 2 on Right output.
- DECODESEL=1 for MPEG1. The MC bit in MC_OFF register should be set.
- DECODESEL=2 for MPEG2. The MC bit in MC_OFF register should be set.
- DECODESEL=9 for MP3.
- Output channel 1 on both L/R outputs,
- Output channel 2 on both L/R outputs,
- Mix channels 1 and 2 to monophonic and output on both L/R,
- Output channel 1 on Left output, and channel 2 on Right output.
