Abstract

Joint source-channel decoding of variable length codes for image and video streaming transmission over unreliable links, such as wireless networks, is a subject of increasing interest. We first provide an analysis of available redundancy in compressed video data produced by some commonly used standardized codecs. Then, we show that a significant improvement in decoding performance can be achieved when additional image and video data properties are taken into consideration. Finally, performance results for improving video decoding over wireless channels are presented.
