Abstract
This paper presents an error concealment strategy for improving the quality of compressed video data when transmitted over noisy communication channels. Data partitioning is used to enable the recovery of motion information when the compressed bitstream is corrupted by channels errors. At low bitrates the motion data is a significant part of the entire video stream and its recovery enables the decoder to perform motion compensated error concealment and hence maintain adequate video quality. The technique is shown to provide superior decode video quality over wide variety of channel errors, bit rates and test sequences. In order to enable effective error concealment the partitioned motion and texture data are separated a motion marker. The motion marker needs to be unique from nay valid combination of the motion VLC data. In this paper, we also present an efficient search algorithm to identify such a motion marker with good error resilience properties. This error concealment technique w...
