1. A circuit for decoding data, said circuit comprising:

  • a processor for demultiplexing a plurality of elementary streams from a multiplexed stream, wherein each of the plurality of elementary streams comprises portions, wherein each of the portions comprises time stamps;

    a system clock for maintaining a clock reference;

    a plurality of FIFOs corresponding to the plurality of elementary streams for queuing each of the plurality of elementary streams, wherein each of the plurality of FIFOs comprise a front end, and wherein the front end of each of the plurality of FIFOs stores the portion of the corresponding FIFO that comprises a time stamp that is proximate to the clock reference; and

    at least one decoder for decoding selected ones of the plurality of elementary streams by decoding portions at the front end of the FIFO corresponding to the selected ones of the plurality of elementary streams and a newly selected one of the plurality of elementary streams by switching from decoding portions at the front end of a FIFO corresponding to one of the selected ones of the plurality of elementary streams to decoding portions at the front end of a FIFO corresponding to the newly selected one of the plurality of elementary streams.
