Active 4d tele-vision

3D television, 3D movie experiences, 3D tele-immersive and tele-presence environments, and extensive 3D gaming environments from Nintendo and Microsoft are becoming integral parts of our lives. Further advances in stereo and multi-view video, 3D graphics, spatial audio, Wii-like interface, 3D displays, and other multi-modal sensory devices, all contributing to acquisition, generation, display and control of new 4D media, already have and will have major impact on the next generation of multimedia systems and networks. In this talk we will discuss vision of active 4D multimedia delivery systems and the challenges of providing interactive, immersive participation and pervasive 4D delivery to millions of viewers. The problems for the multimedia system/networking community range from developing next generation of distributed algorithms, protocols and services organizing the 4D stereo and multiview/ spatial content over Content Distribution Networks, to developing easy and flexible configuration and deployment capabilities of the new cyber-physical 4D multimedia systems as well as new services on diverse devices to enable them playing and actively controlling content on these active 4D tele-vision systems.
