In this paper we compare and evaluate two multicast approaches for delay sensitive media distribution in P2P networks. First approach is based on cooperative m-ary trees, while the second approach is based on a cooperative mesh network. Both schemes exploit the full upload capacity of the participating peers and their proximity relation. Our delivery strategy involves the full cooperation between...
This paper describes the ROMEO architecture for live 3D multi-view video delivery over peer-to-peer networks. The scope of the European founded Integration Project ROMEO encompasses addressing the challenges of live multiview video delivery over heterogeneous networks (WiFi, LTE, DVB, etc.) and diverse user equipment (mobile, portable, fixed). In order to achieve seamless uninterrupted 3D video delivery...
Online forums have long since been the most popular platform for people to communicate and share ideas. Nowadays, with the boom of multimedia sharing, users tend to share more and more with their online peers within online communities such as forums. The server-client model of forums has been used since its creation in the mid-1990s. However, this model has begun to fall short in meeting the increasing...
Peer-to-Peer networks are widely used in media transmission because of its excellent network scalability. Scalable media service is proposed to adapt to different terminal processing abilities. For stratified characteristics of progressive meshes, scalable video, this paper propose a kind of P2P progressive transmission based on multiple implied tree cover. It makes use of several implied tree cover...
This paper presents the design of a platform for distribution of multimedia content streams supported through innovative techniques, both in terms of media encoding and media distribution. The platform architecture accommodates the use of scalable media coding techniques, including both standard and state of the art research methods (wavelets, multiple description coding), combined with new transport...
It is a great challenge to guarantee the service quality and reliability in the large scale peer-to-peer (P2P) networks of video-on-demand systems. This paper proposes a new multilevel P2P architecture, which can avoid the disadvantages of the centralized P2P and the pure P2P architectures while efficiently combine their merits. Methods are provided to design and realize the main distributed nodes...
Due to their ability to overcome many shortcomings associated with the contemporary client-server paradigm, Peer-to-Peer (P2P) networks have attracted phenomenal interests from researchers in both academia and industry. Interactive and multimedia streaming applications using P2P networks are, however, often prone to long startup delays, which disrupt the smooth playback and undermine users' perceived...
The cooperation among peers has been a key factor in the success of peer-to-peer (P2P) media streaming systems. However, practical observations corroborate the prevalence of free riders in existing P2P systems, which significantly degrade the performance of the systems. In this paper, we investigate the design of an incentive mechanism for P2P media streaming and propose a barter-based incentive mechanism...
A post-payment copyright system is used to legalize copyrighted music files which user has obtained illegally. We compare a post-payment copyright system to an online music shop by analyzing three scenarios using techno-economic modeling and risk analysis. According to our analysis, a post-payment copyright system is potentially a more profitable business than an online shop when no media replacement...
Membership service is an essential problem in peer-to-peer (P2P) networks since many p2p applications such as media broadcasting and content distribution require a high performance overlay structure to deliver satisfying quality of service (QoS). The speed a peer locating a good neighbor can greatly affect the QoS of the application running on that peer. In this paper, we present a new mesh-based...
We consider the on-demand delivery of layered video over peer-to-peer (P2P) networks. A parallel server architecture enables the service of requests by more than one server, thus reducing load at individual servers and dispersing network load. In a P2P network, peer upload bandwidth is limited and heterogenous, so a P2P streaming session may involve multiple supplying peers of different uplink. Partitioning...
