Abstract:
Delivering experience enriched with a plethora of media devices, contents, and services will become one major theme of research for the next generation distributed multimedia application such as tele-immersive environment and computer supported collaborative workspace. Those applications are characterized by multiple participatory sites with each hosting multiple semantically correlated media streams. How to establish this type of multi-site/multi-stream applications is a challenging problem due to the lack of a holistic distributed infrastructure that would exploit high-level semantic relationships between streams and support efficient content dissemination across multiple sites. In this talk, I will explore this problem under the context of 3D tele-immersive environments and illustrate the approach based on ViewCast. The idea of ViewCast revolves around the view semantics of 3D video rendering for smart multi-stream coordination in content dissemination. I will present cha!llenges and design issues of ViewCast followed by experimental results.
