In multi-tree-structured Peer-to-Peer (P2P) video streaming, video streams are delivered from the source peer to subscribing peers in such a way that each stream is divided into several sub-streams and those sub-streams are delivered through different spanning trees. In this paper, we focus on the delivery of all sub-streams to [Formula: see text] subscribers through spanning trees of depth two each, which will be referred to as the 2-hop delivery of sub-streams. The main contribution of the current paper is the derivation of a tight lower bound on the upload capacity of homogeneous peers so that 2-hop delivery is possible if and only if the upload capacity of each peer is greater than or equal to the derived bound.

P2P video streaming combining SVC and MDC In this paper we propose and evaluate a combined SVC-MDC (Scalable Video Coding & Multiple Description Video Coding) video coding scheme for Peer-to-Peer (P2P) video multicast. The proposed scheme is based on a full cooperation established between the peer sites, which contribute their upload capacity during video distribution. The source site splits the video content into many small blocks and assigns each block to a single peer for redistribution. Our solution is implemented in a fully meshed P2P network in which peers are connected to each other via UDP (User Datagram Protocol) links. The video content is encoded by using the Scalable Video Coding (SVC) method. We present a flow control mechanism that allows us to optimize dynamically the overall throughput and to automatically adjust video quality for each peer. Thus, peers with different upload capacity receive different video quality. We also combine the SVC method with Multiple Description Coding (MDC) to alleviate the packet loss problem. We implemented and tested this approach in the PlanetLab infrastructure. The obtained results show that our solution achieves good performance and remarkable video quality in the presence of packet loss.
