Abstract

We consider the transmission of MPEG-II compressed video over noisy wireless ATM channels. This has applications in mobile digital video, where high cell loss ratios are observed. We propose techniques for substantially improving the resilience of MPEG-II to cell losses without the addition of any redundancy. Using the techniques outlined in this paper, graceful degradation performance appears possible to cell loss ratios exceeding 1 in 10, long after unprotected MPEG-II pictures are lost
