Paper Abstract

Layered coding has been proposed as a method of 'quality adaptation' for the Internet's best effort service model. The disadvantage of layered coding is that if the base layer packets are lost, the enhancement layers are rendered useless. To achieve error free transmission of the base layer, ARQ could be used, but this limits the performance of LC, due to the strict timing constraints of real time transmission. In this paper we compare Multiple Description Coding, an alternative scalable scheme, without retransmission to Layered Coding with retransmission for a wide range of scenarios. These scenarios include network with no feedback support, networks with long RTTs (WANs) and applications with low latency requirements.
