Program for ACM Workshop on Advanced Video Streaming Techniques for Peer-to-Peer Networks and Social Networking

Workshop website: http://www.p2pstreaming.eu/
Workshop date/location: 29th October 2010, Florence, Italy (co-located with ACMMM'10)
ACM Multimedia: http://www.acmmm10.org/



Workshop presentations: No central server will be used for oral presentations at the Conference Workshops. Authors can either use their own laptops or the PC available in each Workshop room (Windows based machine). Authors are invited to check this program page to see the time slots allocated for oral presentations. For poster and demo sessions at the Workshops, boards are available that can hold a poster up to 100 cm width x 250 cm length (3.28 ft x 8.2 ft). 

Finally, we also invite you to refer to the Conference web page (http://www.acmmm10.org/) for any further information about venue, travel, weather, accommodations, restaurants, and so on.

Closed Swarms by Njaal Borch (Norut IT, Norway)
Abstract: In the search for commercial opportunities within online media distribution, Closed Swarms has been designed to provide content providers with a flexible, distributed authentication mechanism for P2P media distribution. Closed Swarms allow the provider control of bandwidth costs, yet it can enable new business models which might be better suited for the Internet Age, such as freemium solutions or added benefits for paying customers. We will demonstrate how Closed Swarms can be used to provide a free, non-guaranteed community service while logged-in users are provided with a full VOD experience.

Visualizing and Reducing Wait Delay in Periodic Butterfly Communication by Philipp Berndt (Technische Universität Berlin, Germany)
Abstract: Butterfly graphs are probably best known from their use in the Fast Fourier Transform (FFT) algorithm. A different use is in P2P VoIP Conferencing, where each node combines the audio streams it receives, before forwarding the data to the next stage. Dead time between the reception and the relaying of audio data adds up along the data paths to an overall latency that impairs the communication experience. This wait delay heavily depends on the send phase offsets between the nodes. Our demonstration shows how this problem can be interactively visualized and studied, what relationships exist and which methods can be employed to minimize overall wait delay.


Developing P2P Streaming Applications with GRAPES by Luca Abeni (University of Trento, Italy)
Abstract: In this demonstration, it will be shown how to use the GRAPES library to build a simple P2P application, either single-threaded or multi-threaded (the demo application will show how the GRAPES API allows to change the structure of the application from single-threaded to multi-threaded by simply modifying the main application loop). It will also be shown how to easily change the implementation of a GRAPES module (the peer sampler), and the impact of such a change on some performance metrics will be evaluated.

NextShareTV demo by P2P-Next (http://www.p2p-next.eu)
Abstract: The NextShareTV is a Set-top-box confirming to the NextShare platform, developed as part of the P2P-Next project. As a NextShare device, it collaborates with NextSharePC implementations as well, bridging the TV set and the PC in a single content swarm.
