Scalable multiple description video coding using successive refinement of side quantizers

In this paper, we present a new method for scalable multiple description video coding based on motion compensated temporal filtering and multiple description scalar quantizer with successive refinement. In our method quality scalability is achieved by successively refining the side quantizers of a multiple description scalar quantizer. The rate of each description is allocated by considering different refinement levels for each spatio-temporal subband. The performance of the proposed scheme under lossless and lossy channel conditions are presented and compared with single scalable description video coding.
