Abstract

This paper propose a flexible and robust unbalanced multiple description coding and transmission scheme,which is capable of quickly recovering from packet losses and ensuring continuous playback,and further adaptive to both multiple path and single path transmission.Furthermore,this paper discusses the problem of rate allocation between different descriptions when only single path transmission is available and proposes an approximate while efficient rate allocation scheme with the help of two-state Markov link model and a representative rate-distortion model.The experimental results demonstrate the effectiveness of the proposed scheme.
