Coordinated application of multiple description scalar quantization and error concealment for error-resilient MPEG video streaming

Historically, multiple description coding (MDC) and postprocessing error concealment (ECN) algorithms have evolved separately. In this paper, we propose a coordinated application of multiple description scalar quantizers (MDSQ) and ECN, where the smoothness of the video signal helps to compensate fo...
