Abstract
A system and method for receiving damage data in a bitstream of encoded data is disclosed. A plurality of candidate decodings for a plurality of blocks are generated. A measure is generated for each block based upon at least an image portion of the candidate decodings. Compatibility is determined between adjacent blocks of the plurality of blocks. A candidate decoding is selected based upon the measure and the compatibility of adjacent blocks. In one embodiment, this is used in the transmission of video signals over a potentially lossy communications channel.
