Abstract :
In this paper, a novel scheme for scalable distributed video (SDVC) is introduced, which dealing with quality scalabilities. More specifically, efficient H.264/AVC intra-frame coding is used to obtain a base quality layer, the residual between the base layer and the original video is encoded by distributed video coding (DVC) with SW-SPIHT to generate the enhancement layer. The side information is generated by the residual between the base layer and the frame interpolated by motion estimation. Since the residual coding exploits the similarity between the base layer and enhancement layer, experimental results show this SDVC approach is more efficient than the referenced but with similar encoding computation.
