Nov 02, 2006: TEEVE: Next Generation Architecture for Tele-immersive Environments
Filed in: IBM Lecture
Series
Dr. Klara Nahrstedt, University of Illinois at
Urbana-Champaign
Tele-immersive 3D multi-camera, multi-display room environments are emerging and with them new challenging research questions. One important question is how to organize the large amount of visual data, being captured, processed, transmitted and displayed, and their corresponding resources over current COTS computing and networking infrastructures so that "everybody" would be able to install and use tele-immersive environments for conferencing and other activities. In this talk, I will present a novel cross-layer control and adaptive streaming framework over general purpose delivery infrastructure, called TEEVE (Tele-immersive Environments for EVErybody). TEEVE aims for effective and adaptive coordination, synchronization and soft QoS- enabled delivery of tele-immersive visual streams to remote room(s).
Our current initial TEEVE experiments between UIUC and UC Berkeley show that we can sustain communication of up to 12 3D video streams with up to 5 frames per second for each stream, rendering therefore up to 5 4D video frames per second. I will discuss the successes and the various challenges that still remain in this very interesting application.
This is a joint work with Zhenyu Yang, Wanmin Wu, Bin Yu, and Ruzena Bajcsy.
