NOSSDAV 2012, the 22nd SIGMM Workshop on Network and Operating Systems Support for Digital Audio and Video, will be held in Toronto, Canada, on June 7-8 2012. As in previous years, the workshop will continue to focus on both established and emerging research topics, high-risk high-return ideas and proposals, and future research directions in multimedia networking and systems, in a single-track format that encourages active participation and discussions among academic and industry researchers and practitioners.

The workshop seeks research papers in all areas of multimedia networking and systems. Authors are especially encouraged to submit papers with real-world experimental results and real data sets. Topics of interest include (but are not restricted to):

Operating system, middleware and network support
cloud and peer-to-peer system architectures
Media streaming, distribution and storage support
Web 2.0 systems and social networks
Wireless networks and embedded systems for multimedia applications
Multi-core and many-core architecture support
Networked GPUs, graphics and virtual environments
Networked games / Real-time immersive systems
Multimedia communications and system security

In particular, we are interested in soliciting papers that discuss system-level support for social media and social networking, papers that focus on improving performance with multi-core and many-core processors, as well as papers that focus on multimedia applications on mobile devices and/or in a cloud computing environment.
