Patent ID: 8102916

Claim:
A method for changing a media stream of a first compression format to a media stream of a second compression format, the method executed by a processor and comprising: receiving a media stream of the first compression format, said media stream of the first compression format comprising a frame of media of the first compression format, the frame of media of the first compression format comprising a first motion vector, a first error term and a plurality of compression parameters; converting the media stream of the first compression format to an intermediate media stream of an intermediary compression format in a compressed domain, the intermediate media stream comprising a plurality of frames in the intermediary compression format, and the frames in the intermediary compression format compressed using intraframe compression without motion compensation; generating a media stream of the second compression format from the intermediate media stream, the media stream of the second compression format comprising a frame in the second compression format and having a second motion vector and a second error term; and sending the media stream of the second compression format over a computer network.
