Coordinated Media Streaming and Transcoding in Peer-to-Peer Systems

In this paper we study the problem of multimedia streaming and transcoding in P2P systems. We propose a multimedia streaming architecture in which transcoding services coordinate to transform the streaming data into different formats and adapt to both the QoS requirements of the applications and to the availability of the system resources. Our techniques are entirely distributed, use only local knowledge and scale well with the size of the system. Extensive simulation results validate the performance of our approach.
