Abstract

Multiple description coding (MDC) offers a competitive solutionfor video transmission over lossy packet networks,with a graceful degradation of the reproduced quality as theloss rate increases. This paper illustrates how redundantpictures, an error resilience tool included in H.264/AVC,can be employed in conjunction with multiple state videocoding scheme, previously proposed in the literature. Theproposed MDC solution is shown to provide superior performanceto state-of-the-art techniques, in terms of improvedaverage luma peak-signal-to-noise-ratio (PSNR), fewer temporalfluctuations in the picture quality, and improved robustnessto bad estimation of the loss probability in thenetwork.
