Patent ID: 6959042

Claim:
A method of applying information obtained from compressed video data to statistical remultiplexing, comprising: receiving a compressed bitstream including compressed video data; parsing the compressed video data; generating one or more compression statistics from the parsed compressed video data; and providing information associated with the compression statistics to a statistical remultiplexer; wherein generating one or more compression statistics from the parsed compressed video data comprises: counting a number of motion vectors in the parsed compressed video data for a plurality of macroblocks in a picture; and generating one or more correlation measures corresponding to the picture based on the number of motion vectors in the picture; wherein generating one or more compression statistics from the parsed compressed video data further comprises: counting a number of motion vectors in a forward direction with respect to the picture; wherein generating one or more correlation measures is based on the number of motion vectors in the picture and the number of motion vectors in the forward direction with respect to the picture.
