ABSTRACT:
A signal processing method and apparatus are described for demultiplexing selected components (especially audio signals) from a multiplexed data stream. Each of the desired channel components has a unique identification code detected by a processor parsing the contents of a received data buffer between the disc reader and the demultiplexer. The demultiplexer is set up to output received data channel streams having a specific identification code different from any of those assigned to the channel streams originally. Prior to demultiplexing, the identification code for a desired one of the channel streams is altered by the processor to the specific identification code as it passes through the buffer in order to avoid re-setting the demultiplexer.
