Tele-immersive 3D multi-camera room environments are starting to emerge
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 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) over Internet2 networks.

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, Jin Liang,
Ruzena Bajcsy and Sang-Hack Jung.
