C A L L F O R P A P E R S ------------------------------------------------------------ Elsevier Journal Signal Processing: Image Communication SPECIAL ISSUE ON ADVANCES IN VIDEO CODING AND STREAMING FOR P2P NETWORKS Submission deadline: January 31, 2011 ------------------------------------------------------------ In the modern era, there has been an unprecedented increase in the creation and consumption of digital information. In addition, with the advancement of multimedia signal processing/compression technology and the wide deployment of wired/wireless networks, there is an increasing demand for multimedia communication services. However, Peer-to-peer (P2P) multimedia communication systems have received significant attention especially in the past few years. In these systems, a client receives a requested multimedia stream from multiple senders (peers), instead of relying on a dedicated streaming server. Since receiving peers are also potential senders to other peers, the system capacity grows and the reliance on the dedicated server diminishes as more peers join. Thus, P2P streaming systems have the potential to scale the large user communities in a scalable and cost-effective manner. Advanced multimedia processing often attempts to optimize the coding efficiency and introduces higher dependency between the processed data, resulting in a fundamental challenge to robust data communication. On the other hand, P2P systems due to limited capacity and unreliability of peers, mechanisms are needed to efficiently manage the resources contributed by peers and to adapt to the dynamic nature of the network. Therefore, we are facing unprecedented challenges in multimedia communications in P2P networks. The aim of this special issue is to provide all research challenges related to improve the end-to-end Quality-of-experience (QoE) of the multimedia communication over P2P networks. This issue calls for high quality, original contributions including both theory and practical oriented papers. * TOPICS OF INTEREST include, but not limited to, - Novel live or video-on-demand P2P streaming architecture - Scalable video transmission over P2P networks - Multiple description coding in P2P networks - Robust streaming, and error resilience in P2P environment - Peer-assisted content distribution networks - Wireless P2P streaming - Security and data integrity in of P2P streaming systems - Incentive and economic issues of P2P streaming systems Best regards, --Frederic Dufaux -- _______________________________________ Frederic Dufaux Directeur de Recherche CNRS LTCI UMR 5141 Telecom ParisTech 46 rue Barrault 75 634 Paris Cedex 13, FRANCE email: frederic.dufaux@telecom-paristech.fr tel: +33 1 45 81 79 62 fax: +33 1 45 81 71 44 mobile: +33 6 21 33 09 27 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Editor-in-Chief Signal Processing: Image Communication
