1. A data stream synchronizer comprising:

  • a first decoder configured to receive a first encoded data stream and to output a decoded first data stream, wherein the first encoded data stream has a first bit rate during an information interval;

    a second decoder configured to receive a second encoded data stream and to output a decoded second data stream, wherein the second encoded data stream has a second bit rate during the information interval;

    a first buffer configured to accumulate the first decoded data stream for at least one information interval and to output a frame of the first decoded data stream each interval period;

    a second buffer configured to accumulate the second decoded data stream for at least one information interval and to output a frame of the second decoded data stream each interval period; and

    a combiner configured to receive the frame of first decoded data stream and the frame of second decoded data stream and to output a synchronized frame of first and second decoded data streams.
