- W2004192927 abstract "Video broadcasting is a popular application of wireless network, whose main challenge is to accommodate different users with different channel conditions. Recently, a novel `D-Cast' approach based on distributed source coding (DSC) is proposed. It can avoid error propagation and still achieve high compression efficiency in inter frame coding by utilizing coset coding and soft broadcast. However, D-CAST is not very efficient because of rough side information. In this work, we present a novel soft mobile video broadcast approach based on side information refinement algorithm (SIR-CAST) to improve the quality of the side information. Moreover, SIR-Cast optimizes the estimate of the quantifying step (Qstep) which is corresponding to the refined side information. Thus, SIR-CAST outperforms D-CAST about 1dB-2dB in video PSNR while maintaining the similar graceful degradation feature as D-CAST." @default.
