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 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.
Joint work with Dr. Zhenyu Yang (Florida International University), Wanmin Wu
(University of Illinois at Urbana-Champaign), Dr. Gregorij Kurillo (UC Berkeley)
and Prof. Ruzena Bajcsy (UC Berkeley).
Nahrstedt is a professor at the University of Illinois at Urbana-Champaign,
Computer Science Department. Her research interests are directed towards
multimedia middleware systems, quality of service(QoS), QoS routing, QoS-aware
resource management in distributed multimedia systems, and multimedia security.
She is the coauthor of the widely used multimedia books "Multimedia: Computing,
Communications and Applications" published by Prentice Hall in 1995, and

of the IEEE Communication Society Leonard Abraham Award, the Ralph and Catherine
Fisher Professorship Chair, University Scholar Award and Humboldt Research
Award. She was the editor-in-chief of ACM/Springer Multimedia Systems Journal
(2000-2005), the general co-chair of ACM Multimedia 2006, the general chair of
ACM NOSSDAV 2007, the general chair of Percom 2009, and she is currently the
elected chair of the ACM Special Interest Group in Multimedia (2007-2011).
Klara Nahrstedt received her BA in mathematics from Humboldt University, Berlin,
in 1984, and M.Sc. degree in numerical analysis from the same university in
1985. She was a research scientist in the Institute for Informatik in Berlin
until 1990. In 1995 she received her PhD from the University of Pennsylvania in
the Department of Computer and Information Science. She is a member of ACM and
Fellow of IEEE.
