Abstract (en)

[origin: WO2009076178A1] A system and method are described for protecting 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; generating a forward error correction (FEC) code for tiles encoded using the first compression format; transmitting the FEC code with each of the tiles encoded using the first compression format to a client.
