Contents Intro.

Multiple tele-immersive 3D multi-camera, multi-display room environments are emerging and with them new challenging research questions. One important question is how to disseminate the multiple sources per room efficiently across multiple participating rooms using current COTS computing and networking infrastructures. In this talk, I will present a novel cross-layer control, adaptive multicasting framework with view dissemination, called View-Casting. View-Casting aims for (1) effective and adaptive coordination, synchronization and soft QoS-enabled delivery of tele-immersive visual streams to remote rooms, and (2) effective view-casting model for different view dissemination in the multi-party 3D tele-immersive environments. I will discuss different resource optimization and routing strategies to achieve robust view-casting as different rooms join and leave the tele-immersive sessions. The simulation results and partial TEEVE system experiment results confirm the soundness of our design and approach.
