Abstract :
In this paper, a novel framework for multiple description coding of video is presented. The proposed scheme is based on a wavelet source coder and an efficient methodology for the generation of multiple descriptions. An algorithm is also presented for the optimal, in the sense of maximizing reconstruction quality, allocation of redundancy among the descriptions. Experimental results for the transmission of video using two descriptions demonstrate the efficiency of the proposed method.
