Method of lossy decoding of bitstream data

Abstract

Disclosed herein is a method of lossy decoding of bitstream data. The method comprises the steps of decoding the bitstream data having a plurality of symbols to provide an image stream having a plurality of image blocks, marking an image block with a first identifier having a spatial position associated with a location when an invalid symbol is encountered, discarding the bitstream data until a resynchronization code is decoded, marking the image block associated with the resynchronization code with a second identifier, decoding the image stream to provide a plurality of display frames having a plurality of display blocks, comparing the display blocks of a display frame for similarity between the display blocks of a previous display frame to determine display blocks having errors, and replacing the display blocks having errors with previous display blocks corresponding to a similar spatial position.
