Abstract
A video sequence including images in the form of digital samples is encoded by: subsampling the video sequence to produce: a number N of multiple descriptions of the video sequence, each multiple description including 1/N samples of the video sequence, and a subsampled version of the sequence, the subsampled version having a resolution lower or equal to the resolution of the N multiple descriptions. The N multiple descriptions and the subsampled version are subjected to scalable video coding (SVC) to produce an SVC encoded signal having a base layer and N enhancement layers predicted from said base layer. The subsampled version of the sequence and the N multiple descriptions of the video sequence constitute the base layer and the enhancement layers, respectively, of the SVC encoded signal.
