Multi-Frame Compression

摘要

A system and method for compressing data is provided. An embodiment comprises building an adaptive global codebook for each scene in a sequence of video frames. Each frame in the sequence of frames is encoded based on a different encoding order that facilitates an efficient codebook update. Context models for the currently encoded macroblocks are based on temporally and spatially neighboring macroblocks and a global codebook.

1. A method of coding a sequence of frames, the method comprising:
receiving a first frame at an input port; receiving a second frame at the input port; specifying a first encoding order of macroblocks for the first frame; and specifying a second encoding order of macroblocks for the second frame based at least in part on the encoding order of the first frame, wherein the second encoding order is different from the first encoding order.
