SYSTEM AND METHOD FOR PROTECTING CERTAIN TYPES OF MULTIMEDIA DATA TRANSMITTED OVER A COMMUNICATION CHANNEL

摘要

A system and method are described for encoding certain types of multimedia data transmitted over a communication channel. For example, one embodiment of a computer-implemented method comprises: logically subdividing each of a sequence of images into a plurality of tiles, each of the tiles having a defined position within each of the sequence of images, the defined position remaining the same between successive images; encoding one or more of the tiles in each image of the sequence of images using a first compression format and encoding the reminder of the tiles in each image using the second compression format, the second compression format dependent on tiles previously-encoded by the first and/or the second compression formats. Additionally, a forward error correction (FEC) code may be generated for tiles encoded using the first compression format.
