The MPEG-2 Audio standard defines multi-channel extensions to the MPEG-1 standard. Up to five full audio band width channels plus sub woofer channel and up to seven additional multi lingual channels are defined in the transmission format. However, due to the backward compatibility to MPEG-1, the overall bit rate which is available for all these channels is limited. On simpler systems a tradeoff between the number of channels and the audio quality is necessary. This paper describes an advanced MPEG-2 multi-channel system based on MPEG Audio Layer III.
