1. A method for converting digital video from a first compressed format to a second compressed format, the method comprising:

  • receiving an input digital video stream in said first compressed format;

    demultiplexing said input digital video stream so as to generate a multiplicity of constituent data streams, wherein said constituent data streams include a compressed data stream;

    decompressing said compressed data stream so as to generate a decompressed data stream;

    compressing said decompressed data stream so as to generate a recompressed data stream, wherein said recompressed data stream is more compressed than said compressed data stream and wherein said recompressed data stream conveys identical semantic information as said compressed data stream; and

    multiplexing said recompressed data stream and a subset of said constituent data streams that was not subject to said decompressing into an output digital video stream in said second compressed format.
