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

Camere-ready deadline extension: July 26, 2010
Workshop held within ACM Multimedia, 25-29 October 2010, Firenze, Italy


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

Important Dates
  • Paper submission: June 1014, 2010 (extended)
  • Notification of acceptance: July 10, 2010
  • Camera-ready submission: July 2026, 2010 (due to constraints imposed by ACM)
  • 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.
