METHOD AND APPARATUS FOR ENCODING BITSTREAMS USING ROTATION

摘要

The present invention includes a system and method for encoding data by altering data of a rotation block by a rotation factor dependent on data of a key block. In one embodiment, the data includes compression parameters that are descriptive of compressed data. In one embodiment, data of the second or rotation block is altered by calculating a rotation factor from data of a first or key block and altering data of second block in accordance with the rotation factor. In another embodiment, the present invention includes a method for recovering data when there are data losses by determining candidate rotation values for full decoding data of the second block and selecting a rotation value from the candidate rotation values corresponding to the first block data.
