Abstract: This talk will present some technical challenges in high definition video coding and processing to meet the paradigm shifting trends for future digital entertainment for consumers. Traditional consumer video services have been in the broadcasting mode, from terrestrial TV, to satellite and cable services, in which a single encoder is able to serve millions of decoders. The design principle has been the simple decoder of volume sets at the expense of very complicated encoder. The proliferation of mobile devices with video capture capabilities in the recent years has resulted in a paradigm shift trends that require simple encoder for the mobile devices. The burden of the performance has now shifted to decoder that resides at consumer’s home to manage volumetric video captures with desktop computers. This paradigm shift thus created an opportunity for developing emerging video technology to meet the challenges in high performance video decoding for digital entertainment. In this talk, we will examine the bottleneck in the distributed video coding and offers some insight in future research directions. We will also present an example of new video coding schemes based on distributed source coding for the developing scalable schemes from progressive high definition TV from interlaced video. Finally, new perspectives will be offered for the next generation true ubiquitous mobile digital media entertainment.
Speaker Bio: Chang Wen Chen joined the University at Buffalo, State University of New York in January 2008 as Professor of Computer Science and Engineering. He has been Allen Henry Endow Chair Professor of Electrical and Computer Engineering at the Florida Institute of Technology since July 2003. He was on the faculty of Electrical Engineering Dept. at the University of Rochester from 1992 to 1996, on the faculty of Electrical and Computer Engineering Dept at the University of Missouri-Columbia from 1996 to 2003. He also served as the Head of Interactive Media Group at David Sarnoff Research Labs in Princeton from 2000 to 2002, managing multi-million dollar research projects in video coding and wireless video communications.
Currently, he is the Editor-in-Chief for IEEE Trans. Circuits and Systems for Video Technology. He has been an Editor for numerous IEEE Transactions and Journals. He has served as Conference Chair for several major IEEE and SPIE conferences related to mobile wireless video communications and signal processing. His current research interests include reliable and secure multimedia communications over mobile wireless channels; digital video coding, processing, analysis, and embedded implementation; medical image analysis and biomedical information processing; distributed source coding and digital signal processing for communications; and collaborative signal processing and data aggregation for sensor networks. His research is supported by NSF, DARPA, Air Force, NASA, Whitaker Foundation, and Kodak.
He received his BS from University of Science and Technology of China in 1983, MSEE from University of Southern California in 1986, and Ph.D. from University of Illinois at Urbana-Champaign in 1992. He was elected an IEEE Fellow for his contributions in digital image and video processing, analysis, and communications, and elected an SPIE Fellow for his contributions in electronic imaging and visual communications.
