Layered coding has been proposed as a method of 'quality adaptation' for the Internet's best effort service model. The disadvantage layered is that if base layer packets are lost, enhancement layers rendered useless. To achieve error free transmission layer, ARQ could be used, but this limits performance LC, due to strict timing constraints real time transmission. In paper we compare Multiple Description Coding, an alternative scalable scheme, without retransmission Coding with wide range...
