A BIT STREAM BUFFERING AND DEMULTIPLEXING APPARATUS FOR A DVD AUDIO DECODING SYSTEM

摘要

An apparatus for bit stream buffering and demultiplexing for a DVD Audio decoder system uses one demultiplexer to demultiplex both audio program stream and audio still video program stream. Demultiplexed audio still video data is stored in the elementary form of ASVU buffer. Storing elementary data as ASVU buffer reduces the storage space and allows the system to check for syntax error in the program stream level earlier. The demultiplexer also generates an audio still video address pointer table indicating the access address for each audio still video object, thus allowing fast random access by the decoder.
