Abstract: A data processing apparatus for decoding a bitstream includes a channel decoder, a demultiplexer and a plurality of decoders. The channel decoder is used for generating an encoded bitstream data from a received channel data and storing the encoded bitstream data to a buffer, wherein the encoded bitstream contains a plurality types of sectors. The demultiplexer is used for rearranging the stored encoded bitstream data according to the plurality of types and storing sectors corresponding to the same bitstream type in respective regions in the buffer. The decoders are used for decoding the sectors corresponding to the bitstream types, the decoders retrieving the rearranged data from the buffer according to corresponding one of the plurality of types.

Abstract: In a method of controlling multiple decoders in an optical disc player system to read encoded bitstream data divided into multiple sectors from a buffer memory, one of the sectors stored in the buffer memory is read according to a reading pointer associated with one of the decoders that sent out a bitstream request. When a header portion of the sector that is being read from the buffer memory indicates a bitstream type corresponding to that of the bitstream request, a data portion of the sector is transferred to the decoder that sent out the bitstream request, and the reading pointer is adjusted to point to a next one of the sectors stored in the buffer memory. An optical disc player system for implementing the method and an optical disc player system capable of saving the memory bandwidth between a bitstream demultiplexer and a memory are also disclosed.
