1. An apparatus for manipulating compressed digital video information to form manipulated compressed video information, the manipulated compressed video information being a manipulation of data from at least one of a plurality of compressed digital video sources, the apparatus comprising:

  • at least one video input module for receiving compressed video input data from at least one source of the plurality of compressed digital video sources, the at least one video input module comprising a generalized decoder operative to decode the compressed video input data, generate a primary video data stream, and process the compressed video input data and the primary video data stream to generate a secondary data stream; and

    at least one video output module for receiving the primary video data stream and the secondary data stream from the at least one video input module, and being operative to encode the primary video data stream with references to the secondary data stream to form manipulated compressed video output data, whereby the use of the secondary data stream by the at least one video output module improves a speed of encoding and the manipulated compressed video output data'"'"'s quality.
