Challenges in Internet Video Broadcast and First Steps in Finding Solutions
Abstract:
Television broadcast has been a very successful mass communication tool. As the digital TV is moving into the living rooms of consumers, interactive TV has become an interesting technical and business challenge. One approach is to add interactivity into the digital TV system that uses the traditional broadcast channels. On the other hand, Internet has provided an excellent way for interactivity. However, it is still a challenge to bring TV broadcast to the Internet. The fundamental difference between the Internet and the traditional networks is that the Internet is a distributed shared network while the traditional networks are centralized dedicated networks. Therefore, the Internet is more efficient in terms of bandwidth usage and it allows easy communications from anyone to anyone else. At the same time, the Internet bandwidth varies in a wide range from one user to another (user variations) and from time to time (temporal variations). This makes traditional video coding techniques difficult to match the channel characteristics. From Internet transmission side, there are also challenging problems. The original intention of the Internet design was for distributed reliable communication. To use such a network for video broadcast, in which reaching a large audience is more important than reliable transmission of every bit, we need new tools too. This presentation addresses the issues for bringing Internet TV broadcast into a reality and discusses the initial steps for solutions.
Biography: Weiping Li received his B.S. degree from University of Science and Technology of China (USTC) in 1982, and his M.S. and Ph.D. degrees from Stanford University in 1983 and 1988 respectively, all in electrical engineering. In 1987, he joined the Faculty at Lehigh University, where he is currently a Professor in the Department of Electrical Engineering and Computer Science. Since 1998, he has taken a leave from Lehigh University to work on network streaming video in Silicon Valley, California. He was with Optivision, Inc. in Palo Alto, California, from 1998 to 1999, as the Director of R&D. He is currently with WebCast Technologies, Inc., a start-up company that he co-founded.
Weiping Li has been elected to Fellow of IEEE for contributions to image and video coding algorithms, standards, and implementations. He is currently the Editor-in-Chief for IEEE Transactions on Circuits and Systems for Video Technology. He served as an Associate Editor of the same journal from 1995 to 1999. He has served as an Editor for the Streaming Video Profile Amendment of MPEG-4 International Standard. He is a member of the Board of Directors for MPEG-4 Industry Forum. He served as one of the Guest Editors for a special issue of IEEE Proceedings on image and video compression (February 1995). He served as the Past-Chair (1998-1999) and Chair (1996-1998) of Technical Committee on Visual Signal Processing and Communications of IEEE Circuits and Systems Society. He is the Program Chair of the MPEG-4 Workshop and Exhibition (2000). He was a Co-Chair (1999) and Chair (1997) of Technical Track on Multimedia and Communications in IEEE International Symposium on Circuits and Systems. He served as the Chair of Best Student Paper Award Committee for 1999 SPIE Visual Communications & Image Processing Conference. From 1997 to 1998, he served as the Chair of Working Group on reaffirmation of IEEE Standard 1180 (Specifications for the Implementation of 8x8 Inverse DCT). Since 1995, he has been a member of Moving Picture Experts Group of International Standard Organization.
Weiping Li received the Spira Award for Excellence in Teaching in 1992 at Lehigh University and the Guo Mo-Ruo Prize for Outstanding Student in 1980 at University of Science and Technology of China.

Abstract:
Fascinating growth and rapid development in wireless communications and multimedia technologies have profoundly transformed the technological landscape. We have witnessed an increasing convergence of Internet, Wireless, and Multimedia. Future communication infrastructure is envisioned to have high mobility, full connectivity, and compelling multimedia capability. There, however, exists multiple challenges and difficulties in how to represent, store, access, and deliver multimedia information over a wireless network. This talk discusses these issues, presents on-going research efforts and outlines future directions for wireless multimedia. Some new research results at Microsoft will be demonstrated.
Dr. Ya-Qin Zhang, PhD, FIEEE
Biography:
Ya-Qin Zhang is currently the Managing Director of Microsoft Research in Beijing. He was previously the Director of Multimedia Technology Laboratory at Sarnoff Corporation in Princeton, NJ (formerly David Sarnoff Research Center, and RCA Laboratories). He has been engaged in research and commercialization of MPEG2/DTV,MPEG4/VLBR, and multimedia information technologies. He was with GTE Laboratories Inc. in Waltham, MA and Contel Technology Center in Virginia from 1989 to 1994. He has authored and co-authored over 200-refereed papers in leading international conferences and journals. He has been granted over 40 US patents in digital video, Internet, multimedia, wireless and satellite communications. Many of the technologies he and his team developed have become the basis for start-up ventures, commercial products, and international standards. He serves on the Board of Directors of five high-tech IT companies.
Zhang served as the Editor-In-Chief for the IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS FOR VIDEO TECHNOLOGY (T-SCVT) from July 1997 to July 1999. He was the Chairman of Visual Signal Processing and Communications Technical Committee of IEEE Circuits and Systems. He serves on the Editorial boards of seven other professional journals and over a dozen conference committees. He has been a key contributor to the ISO/MPEG and ITU standardization efforts in digital video and multimedia.
Zhang has been a Fellow of IEEE since 1997. He received numerous awards, including several industry technical achievement awards and IEEE awards such as CAS Jubilee Golden Medal, Richard Merwin Award, and T-CSVT best paper award. He was awarded as the "Research Engineer of the Year"in 1997 by New Jersey Engineering Council. He received the prestigious national award as "The Outstanding Young Electrical Engineering of 1998," given annually to one electrical Engineer in US endorsed by President Bill Clinton.
Zhang received his B.S. and M.S. in Electrical Engineering from the University of Science and Technology of China (USTC) in 1983 and 1985. He received his Ph.D in Electrical Engineering from George Washington University, Washington D.C. in 1989. He graduated from the executive business program at Harvard University.
