  • Playback and monitoring of compressed bitstreams
    Patent number: 6421749
    Abstract: An apparatus for testing a compression decoder, includes a compression encoder having a picture input for receiving picture material and a coding decision input for receiving coding decisions from a set of legal coding decisions, where the compression encoder is adapted to encode picture material utilising the received coding decisions, a generator for generating random coding decisions from the legal set, and a playback device for communicating encoded picture material from the encoder to a decoder under test.
