Recent advances in computing and communications technology make possible
the widespread use of digital video and other continuous media (e.g.,
audio, 2D/3D animations, etc.). Distribution and use of digital video on the
Internet is very different than the distribution and use of conventional video.
Video streams have varying frame rate, image size, bit rate, and hence
quality and video transport uses packet video protocols with varying jitter
(i.e., interpacket arrival times) and relatively high loss rates. We call
this type of video Internet Video. Examples of Internet Video applications
including telecollaboration, distance learning, on-demand video playback,
and other interactive media experiences as well as the more traditional
broadcast media programs.
For the past three years we have broadcast a regularly scheduled program
the "Berkeley Multimedia, Interfaces, and Graphics Seminar" on the Internet
(http://bmrc.berkeley.edu/298). We are developing systems and applications
to support the use of video special effects in the seminar broadcasts.
Rather than integrate a traditional hardware solution, we are designing and
implementing a software-only parallel video effects system using commodity
processors and a high bandwidth, low latency network such as the Berkeley
Network of Workstations architecture.
This talk will discribe our experiences producing the seminar, the system
architecture for the video effects processing system, and preliminary results
on the overhead of temporal parallelism splitting of effects processing.
Professor Rowe received a BA in mathematics and a PhD in information and computer science from the University of California at Irvine in 1970 and 1976, respectively. Since 1976 he has been on the faculty at the University of California at Berkeley where he is now a Professor of Electrical Engineering and Computer Science. He is the founding director of the Berkeley Multimedia Research Center which is an interdisciplinary research group working on applications of multimedia technology to business, education, research, and society. Professor Rowe's current research interests are multimedia applications and databases, video conferencing, hypermedia courseware, and video compression. He heads the research group that developed the Berkeley MPEG1 video tools (i.e., software decoder, parallel encoder, and utilities), the Berkeley Continuous Media Toolkit, and the Berkeley Distributed Video-on- Demand System. He previously worked on programming languages, database application development tools, and network operating systems. Professor Rowe has published over seventy papers on multimedia systems and applications and programming and database systems. He is a member of the editorial board of the ACM Multimedia Systems Journal. He serves on the technical advisory board for several companies (e.g., Be There, Eloquent, and Inktomi) and was a co-founder of Ingres Corporation.
Professor Rowe is being hosted by the Video and Image Processing Laboratory (VIPER) of the School of Electrical and Computer Engineering. Please contact Prof. Edward Delp (ace@ecn.purdue.edu), 494-1740 for more information.
