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

  • interface circuitry configured to receive multiplexed packets from a media source, wherein said multiplexed packets carry a plurality of different individual synchronized streams of audio and video data multiplexed into a single multiplexed data stream;

    controller circuitry configured to;

    examine each of the multiplexed packets and detect an end of each of said plurality of synchronized streams of data in only some of the multiplexed packets forming the multiplexed data stream received by the interface circuitry; and

    modify the multiplexed data stream to be a modified multiplexed data stream by selectively appending markers to each synchronized stream of data within the multiplexed data stream, said markers appended to only indicate those multiplexed packets that include a detected end of a respective synchronized stream of data for each of said plurality of synchronized streams of data within said modified multiplexed data stream;

    demultiplexing circuitry configured to receive the modified multiplexed data stream and demultiplex the modified multiplexed data stream to generate demultiplexed streams of data; and

    presentation processing circuitry comprising a first decoder circuitry configured to decode and output one of the demultiplexed streams of data of a first multimedia type for presentation, and a second decoder circuitry configured to decode and output the demultiplexed streams of data of a second multimedia type for presentation, the first decoder circuitry configured to signal the second decoder circuitry when each of the markers in the demultiplexed streams of data of the first multimedia type are detected.
