Abstract

Abstract

Current Internet video transmission is characterized mainly by variations in throughput and packet loss. Scalable Coding(SC) and Multiple Description Coding(MDC) have been proposed as source coding techniques that are robust to such channel problems. Studies showed that combination of the two approaches(MDSC) can guarantee better qualify adaptation video transmission. Traditional MDSC improves SC by introducing redundancy in base layer so that the chance of receiving at least one description of base layer is greatly enhanced. This idea is further expanded, and a new improved MDSC scheme is proposed in this paper. In the proposed approach, MDC is applied to the base layer of the first order SC, and then the derived descriptions are encoded by second order SCs. The advantage of this approach is that both the coding efficiency and robustness of the coding stream can be simultaneously considered.
