Systems and Networking Seminar: Fall 2009

The goal of this seminar is to allow different faculty members and their groups to get together on a weekly basis to discuss variety of topics ranging from papers published in recent networking conferences such as SIGCOMM, Infocom and systems conferences such as NSDI, SOSP, OSDI etc to even their own research. Every week, one-two persons lead the discussion on a paper. The hope is that in time all those interested in systems and networking can be abreast with cutting-edge (or perhaps the word is bleeding edge) papers in these areas. This seminar is open to all; however, if you are a regular attendee, you are expected to present at some point of time. Note that in some cases, your advisor may volunteer you if you haven't volunteered yourself.

Venue: 3102B
Timing: 2-3pm Wednesdays.

Guest Lecture Abstract:

ViewCast: View Dissemination and Control for Multi-party 3D Tele-immersive Environments

Abstract:
Three-dimensional tele-immersive (3DTI) environments have recently emerged as a new medium of video-mediated collaboration across the Internet. Unlike conventional 2D video-conferencing systems, they can immerse remote users into a shared 3D virtual space for real-time collaboration. However, most existing 3DTI systems work with only two sites due to the huge demand of resources and the lack of a simple yet powerful networking model to handle connectivity, scalability, and quality-of-service (QoS) guarantees.

We propose an innovative and generalized ViewCast model to coordinate the multi-stream content dissemination over an overlay network. ViewCast leverages the view semantics in 3D free-viewpoint video systems to fill the gap between the high-level user interest and the low-level stream management. In ViewCast, only the view information is specified by the user/application, while the underlying control dynamically performs stream differentiation, selection, coordination, and dissemination.
