Keynote Title 1
TItle	¡°Next Generation of System Architectures for Tele-immersive Environments¡±
Presentation File	ESTIMedia2005_keynote1.pdf
Speaker	Professor Klara Nahrstedt (Department of Computer Science - University of Illinois at Urbana-Champaign)
Abstract	The tele-immersive 3D multi-camera room environments are starting to emerge in order to assist in distributed physical activities such as physical therapy, sport activities, and entertainment, and with them new challenging research questions. These environments need 3D multi-camera setups at the sending side and multi-display setups at the receiving side connected via appropriate network infrastructure. One important question is what is the next generation of system architectures that allow to build these environments in a flexible manner, with COTS components and for broader audience. In this talk we will discuss challenges of system architectures as well as present possible solutions. We will investigate the design space between the 3D multi-camera/multi-display tele-immersive edges and the general purpose computing and communication infrastructure available today. Especially, we will analyze on our cross-layer control and streaming framework over general purpose delivery infrastructure, called TEEVE (Tele-immersive Environment for Everybody), the difficulties and effectiveness of tele-immersive architectural constructs such as capturing, reconstructing and displaying 4D content, and coordination, synchronization and QoS-enabled delivery of tele-immersive 3D visual streams to remote room(s) over Internet 2. The first experiments of TEEVE and few other next generation architectures are encouraging, as we start to sustain communication of up to 12 3D streams with several frames per second (e.g., TEEVE can reach around 5 frames per second) over Internet 2, but a lot of work and challenges remain to be solved.
Biography	Klara Nahrstedt is a professor at the University of Illinois at Urbana-Champaign, Computer Science Department. Her research interests are directed towards multimedia systems, 3D multi-camera tele-immersive environments, quality of service(QoS), QoS routing, QoS-aware resource management in distributed multimedia systems, and multimedia security. She is the coauthor of widely used multimedia books such as the `Multimedia: Computing, Communications and Applications' published by Prentice Hall, and ¡®Multimedia Systems¡¯ published by Springer Verlag. She is the recipient of the Early NSF Career Award, the Junior Xerox Award, and the IEEE Communication Society Leonard Abraham Award for Research Achievements. She is the editor-in-chief of ACM/Springer Multimedia Systems Journal, and the Ralph and Catherine Fisher Associate Professor. 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.

Keynote Title 2
TItle	¡°Design of Multimillion-Gate Multimedia SoCs: Where do we stand?¡±
Speaker	Dr. Santanu Dutta ( Senior Member of Technical Staff, nVIDIA Corporation)
Abstract	The talk will essentially investigate how consumer demands and market dynamics continue to influence the features, the designs, and the design methodology. The talk will have four main parts.  Starting in the first part with how the power consumers participate in the digital  revolution, the second part of the talk will focus on the market dynamics and  the market demands. The third part of the talk will identify the high-level design trends as influenced by the consumers and the market. The fourth and final part of the talk will describe the low-level design trends and draw the conclusions.
Biography	Santanu Dutta received his Ph.D. in Electrical (Computer) Engineering from Princeton University in 1996, an M.A. in Engineering from Princeton University in 1994, an M.S. in Electrical (Computer) Engineering from the University of Texas at Austin in 1990, and a B.Tech. (with Honors) in Electronics and Electrical Communication Engineering from the Indian Institute of Technology, Kharagpur, in 1987. From 1987 to 1989, Santanu was a full-time research staff member at the VLSI Design Laboratory of Texas Instruments (TI), Dallas, where he was involved in the research of timing algorithms and development of prototype CAD tools. As a student at UT Austin, on a leave of absence from TI from 1989 to 1991, Santanu's main focus was path-tracing algorithms for interconnect analysis. From 1991 to 1992, he worked part-time at Ross Technology Inc., Austin (Texas) as a circuit designer and a full-custom-layout engineer. From September 1992 till August 1996, he was a doctoral student at Princeton University, working on the design and analysis of video signal processing systems. During this time, he spent a year at AT&T Bell Laboratories (now Lucent Technologies), investigating the impact of deep-sub-micron VLSI techniques on architectural/system design. From August 1996 till April 2005, Santanu was a Design Manager and Architect at Philips Semiconductors, leading a video competence group and managing various SOC and IP design projects targeting the digital television and set-top box markets. Since April 2005, Santanu is with nVIDIA Corporation, as a Senior Member of Technical Staff in the Digital Media Processors group. Santanu's main research interests include design of high-performance video signal processing architectures, circuit simulation & analysis, and design & synthesis of low-power & testable digital systems. He has many refereed publications and several patents pending in related areas. Santanu is an Adjunct Faculty at the Santa Clara University and is a Senior Member of the IEEE.
