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.
