Unified image/bitstream analysis for the robust decoding of compressed video sequences for wireless networks

This paper is concerned with the problem of error detection and correction of MPEG-4 video streams transmitted over lossy networks. The problem is first defined and some relevant detail of the MPEG-4 syntax is presented. The difficulties encountered in articulating this problem within a unified Bayesian framework are explored and two separate frameworks for dealing with error detection and error correction are then presented, along with some results. The paper concludes with some comments on the techniques used and pointers to future plans.
