This paper is concerned with the problem of error detection and correction of MPEG-4 video streams transmitted over lossy networks. The problem is rst deened and some relevant detail of the MPEG-4 syntax is presented. The diiculties encountered in articulating this problem within a uniied Bayesian framework are explored and two separate frameworks for(More)
— The coding of highly compressed data streams involves removing as much redundancy from the stream as possible. However, as redundancy is removed, so is the ability of the decoder to recover from error conditions caused by wireless channels, or other lossy communications links. Standard techniques for providing some protection to the stream against channel(More)
