Around the 2010-2014 time frame it is likely that relevant standards bodies will ratify a worldwide P2P standard. Crafting a P2P standard that is effective, efficient, has an Open Source reference implementation, and can be integrated into television hardware will require cooperation between scientists, industry, and standardisation bodies.

This tutorial presents the state-in-the-art in P2P video search & distribution algorithms, implementations, performance comparisons, and information on standardisation processes with concrete time lines. You will learn what open problems currently exist and how you can contribute improvements to this standardisation processes.

The focus of this tutorial is on the challenging "true P2P systems" with zero-servers which potentially offer unbounded scalability. All relevant research is discussed that is needed to manufacture P2P Internet-only television sets. You will learn about the state-in-the-art algorithms and implementations of searching video content using both keywords and tags. For both video-on-demand and real-time live channel streaming systems the state-in-the-art algorithms and implementations will be discussed. The focus is on the Bittorrent-class of algorithms using non-explicit multicast distribution trees. Standardisation processes will be explained from three sides: a public broadcaster perspective, consumer electronics industry perspective, and a scientific perspective.

A key goal of the tutorial is trying to organise the field of P2P video and improve the level of collaboration amongst scientists. At the tutorial we will present the details of the an Open Source reference implementation which currently defines the state-of-the-art in zero-server P2P video search&playback. This reference implementation plus the swarm emulation toolset for performance evaluation will be discussed in detail. The tutorial extends an open invitation to scientists to contribute to this reference code and submit improvements. The algorithms in the reference implementation will be submitted to the relevant standards setting bodies.
