Abstract:

While the traditional approach to build networked multimedia systems is to
separately design the source coding and transport components (no doubt
influenced by Shannon's separate source/channel theorem), recent research
has shown that for applications such as low-delay streaming, jointly
optimizing the source coding and transport mechanisms can reap additional
benefit. In the first part of this talk, I will overview several video
streaming systems that optimize source coding and transport components
jointly to varying degrees for different application scenarios requiring
error-resiliency or interactivity: reference frame selection for
multi-path video streaming, smart media striping over multiple loss
channels, cooperative peer-to-peer repair for wireless video broadcast,
and community streaming for visual interactivity in networked shared
viewing. In the second part of this talk, I will provide more details to
one system called "interactive multiview video streaming", where an
observer can periodically switch view in a multiview video streaming
session, and discuss the tradeoffs in storage, transmission bandwidth and
interactivity.

Gene Cheung (National Institute of Informatics, ) received
the B.S. degree in electrical engineering from Cornell University, Ithaca,
NY in 1995 and the M.S. and Ph.D. degrees in electrical engineering and
computer science from University of California, Berkeley, in 1998 and
2000, respectively. From 2000 to 2009, he was a Senior Researcher in
Hewlett-Packard Laboratories Japan, Tokyo. He is currently an assistant

professor at National Institute of Informatics, Tokyo, Japan. His research
interests include media transport over wireless networks, joint
source/network coding for single- and multiple-view video streaming, and
rich media interaction. He is a senior member of IEEE and currently serves

as an Associate Editor of IEEE Transactions on Multimedia. He is a
co-recipient of the Top 10% Award in IEEE International Workshop on
Multimedia Signal Processing (MMSP) 2009. He serves as demo co-chair of
IEEE Consumer Communication & Network Conference (CCNC) 2010, technical
program co-chair of International Packet Video Workshop (PV) 2010, and
will chair the special session on cooperative media communication in IEEE
International Conference on Acoustics, Speech and Signal Processing
(ICASSP) 2010, and special session on immersive interaction for networked
multiview video systems in SPIE International Conference on Visual
Communications and Image Processing (VCIP) 2010.
