Live video and IP-TV

Abstract

This Chapter aims at providing a comprehensive insight into the most recent advances in the field of P2P architectures for video broadcasting, focusing on live video streaming P2P live video streaming. After introducing a classification of P2P video solutions, the first part of the Chapter provides an overview of the most interesting P2P IP-TV P2P IP-TV systems currently available over the Internet. It also concentrates on the process of data diffusion within the P2P overlay and complements this view with some measurements that highlight the most salient features of P2P architectures. The second part of the Chapter completes the view, bringing up the modeling efforts to capture the main characteristics and limits of P2P streaming systems, both analytically and numerically. The Chapter is closed by a pristine look at some challenging, open questions, with a specific emphasis on the adoption of network coding in P2P streaming solutions. © 2010 Springer Science+Business Media, LLC.
