This paper proposes an optimized joint source-channel coding methodology with unequal error protection for the transmission of video encoded with the recently developed scalable extension of H.264/MPEG-4 AVC. The proposed methodology uses a simplified Viterbi-based search method which significantly outperforms the classical exhaustive search method in terms(More)
Error concealment is of crucial importance when transmitting digital video material over error-prone channels. Indeed, loss of information can result in severe degradation of the video quality if precautions are not taken to contain the effect and propagation of errors. In this paper, we present an error concealment mechanism that supports quality(More)
