Data Partitioning and Reversible Variable Length Codes for Robust Video Communications

Low bit-rate multimedia communication over wireless channels has received much attention recently. A key challenge in low bit-rate wireless communication is the very high error rate during transmission. This demands error resilient services that exhibit graceful performance degradation while operating in a highly noisy channel. Among video, audio and other multimedia communication modalities, we focus on the errorresilient transmission of video signals over wireless channels in this paper. Specifically, efforts in developing H.263++ Annex V error resilient Data Partitioning with Reversible Variable Length Code (RVLC) are described in detail. The performance over error-prone channels is analyzed and the effectiveness of the syntax is demonstrated with extensive simulations.
