Codage par descriptions multiples pour la transmission vidéo

In this paper, we address the problem of multiple description coding for the transmission over best-effort networks of scalable video sequences obtained with a t + 2D wavelet codec. Unlike previous approaches, which consider redundancy insertion in the spatial domain, in this paper we introduce redundancy in the temporal domain of the video sequence, using motion compensated oversampled dyadic filter banks. We are giving here the framework for building such temporal multiple description schemes based on redundant wavelet decompositions with a reduced redundancy feature. The general approach is applied to video coding.
