Adaptive multicast streaming based on scalable video blocks and TFMCC protocol

This paper presents an architecture for live streaming of scalable video, which is encoded using the H.264 SVC (Scalable Video Coding) standard and transmitted over multicast groups on a peer-to-peer (P2P) network. The architecture has two characteristics: 1) the utilization of a paradigm of video compression based on independent compressed blocks in order to minimize some of the practical difficulties of the decoding process of the H.264 SVC when it is transmitted in real time over unreliable channel; 2) bitstream adaptivity through dynamic quality adjustment of the video blocks on an Internet best-effort environment, leading to a significative improvement in the quality of received video sequences.
