An adaptable spatial-temporal error concealment method for Multiple Description Coding based on error tracking

Multiple Description Coding (MDC) is one of the most efficient methods to combat error-prone channels especially when retransmission is unacceptable. In applications involving scalable, multicast and P2P environments, it is advantageous to use more than two descriptions. In this paper, we present an adaptable temporal-spatial error concealment method based on error tracking to improve the performance of MDC. A Gilbert model is used as the channel model for burst packet loss simulation. Experimental results demonstrate the efficacy of the proposed method.
