Bitplane Selective Distributed Video Coding

This paper presents a BitpLAne SelecTive (BLAST) distributed video coding (DVC) system. In the proposed system, the importance of each bitplane is measured at the decoder, and only the bitplanes with higher importance would be decoded. A minimum-distance symbol reconstruction is proposed to estimate the rest of the bitplanes by using the side information and the decoded bitplanes. The importance is measured with an estimated rate-distortion ratio that makes use of a correlation model for the original source information and the side information. Coding results and comparisons with existing DVC schemes and with H.264 interframe coding are presented to illustrate the performance of the proposed System.
