Recent works have shown how Multiple Description Coding (MDC) proves to be an effective solution for the multimedia transmission over Peer-to-Peer and Content Delivery Networks. However, despite the flexibility and scalability of these novel transmission paradigms, packet streams are still affected by losses, and an effective packet labelling that differentiates the QoS levels for the transmitted...
This paper proposes a method for saving resources of the video distribution server by using peer-to-peer communications. In order to adapt to a time-varying channel, scalable video coding and a fountain code, a Raptor code is used. The Raptor code protects video quality asymmetrically according to the significance of scalable video layers; varying in peer-to-peer networks, as a forward error correction...
Previous works showed that the quality-of-service (QoS) requirements of multimedia applications can be optimally satisfied by pipeline forwarding (PF) by providing end-to-end delay guarantees as well as high network resource utilization. However, the unavoidable mismatch between reserved resources and the unpredictable traffic profile of a video stream has an impact on the resulting application layer...
