Layered streaming in P2P networks has become a hot topic recently. However, the "layered" feature makes the data scheduling quite different from that for nonlayered streaming, and it hasn't been systematically studied yet. In this paper, first, according to the unique characteristics caused by layered coding, we present four objectives that should be addressed by scheduling: throughput,...
Peer-to-peer networks are an increasingly popular solution for the distribution of media content to a large number of users, with limited investments for network infrastructures. The distribution of a real time video stream imposes strict performance requirements such as small playback delays and few frame losses. However, performances are greatly affected by the upload bandwidth of the access networks...
Video distribution through peer-to-peer (P2P) networks using Scalable Video Coding (SVC) has been an active research. And bitstream extraction is an important issue in SVC transmission. In this paper, we propose a global optimal GOP-adaptive Rate-Distortion optimization extraction algorithm for SVC streaming multicasting over P2P networks. This method solves the problem of serving many clients with...
