CfP: ACM Workshop on Advanced Video Streaming Techniques for
Peer-to-Peer Networks and Social Networking
-----------------------------------------------------------------------
Workshop held within ACM Multimedia, 25-29 October 2010, Firenze, Italy

http://www.p2pstreaming.eu

Peer-to-peer (P2P) is a promising technology for video streaming, and
offers advantages in terms of robustness, re-configurability and
scalability. In this context, social networks and social services are
emerging as a potential new driver for content delivery networks.
Specifically, social networks potentially provide a new level of
understanding and knowledge related to the interaction between people
within a virtual space. Many emerging multimedia based services and
applications have started to exploit the ‘social graph’ in new ways for
establishing a basis for social recommendations, filtering etc.). As yet,
one unexplored area of research relates to the exploiting the social graph
for informing adaptive behaviour in P2P-based multimedia systems. On the
other hand, the P2P video technology is still challenging, due to the need
of reducing start-time and churn-induced instability, to the asymmetry of
residential broadband connections, and to high packet loss rates due to
router congestion and transmission errors on the physical network, node
departure from the P2P overlay, strict timing out due to real time
visualization. The lack of guarantee about the actual delivery of the data
may cause drops in the reproduction quality and service outages. The
workshop objective is to solicit novel contributions on all aspects of
P2P-based video coding, streaming, and content distribution which is
informed by social networks.

Topics of interest include, but are not limited to
- Innovative P2P-based video streaming solutions
- P2P-based social media content distribution networks
- Advanced video coding techniques for real-time P2P applications:
layered/scalable video coding, multiple description coding, distributed
source coding
- Identification and design of proper metrics for performance evaluation and
monitoring including Quality of Service/Experience
- Content and context analysis and modelling for P2P-based social media
distribution
- Filtering and recommendation systems
- Error-resilience tools for peer-to-peer multimedia services
- Rate control and bandwidth adaptation for both single streams and multiple
stream multiplexing
- Cross layer optimization issues
- Protocols for peer-to-peer multimedia services
- P2P streaming prototype implementation for both live and on-demand streaming
- Advertisement, payment, and cashing systems
- Applications, standards, and practical deployments

Invited Talk

Important Dates
- Paper submission: June 10, 2010
- Notification of acceptance: July 10, 2010
- Camera-ready submission: July 20, 2010
- Workshop date: October 29, 2010

Submission Guidelines
Papers should not exceed five pages in length, following the ACM proceedings format.
Papers must be original and have not been published or under consideration for
publication elsewhere. Each paper will be reviewed by three members of the program
committee, recognised for their competence in the field. Final decision about
inclusion in the workshop proceedings will be taken by the PC members exclusively
on the basis of the obtained reviews and levels of recommendation. Papers must be
registered using the ACM Multimedia conference management software
(http://www.edas.info/N9045).
Accepted papers will be included in the workshop's proceedings which will be
published together with the proceedings of the ACM Multimedia Conference 2010.
Additionally, a special issue or an edited volume is planed based on the best
papers of the workshop.
