Abstract

The most recent literature indicates multiple description coding (MDC) as a promising coding approach to handle the problem of video transmission over unreliable networks with different quality and bandwidth constraints. We introduce an approach moving from the concept of spatial MDC and introducing some algorithms to obtain sub-streams that are more efficient by exploiting some form of scalability. In the algorithm, we first generate four subsequences by sub-sampling, then two of these subsequences are jointly used to form each of the two descriptions. For each description, one of the original subsequences is predicted from the other one via some scalable algorithms, focusing on the inter layer prediction scheme. The proposed algorithm has been implemented as pre- and post- processing of the standard H.264/SVC coder. The experimental results are presented and we show it provides excellent results.
