Abstract

Recent works have shown how the transmission of multimedia data over Peer-to-Peer networks is significantly improved by the adoption of Multiple Description Coding (MDC) techniques. However, the performance of these schemes can be significantly enhanced by differentiating the Quality-of-Service levels for the transmitted data in order to grant intra-stream and inter-stream diversities among the loss patterns affecting the different descriptions. The paper presents a classification algorithm that addresses a four description MDC scheme and adopts an optimization strategy based on modelling the transmission of packets like a noncooperative game. Different peers are considered as independent players competing for the network resources. The proposed approach improves the quality of the reconstructed sequence without the need of a coordinating node or message passing between the uploading peers.
