ŠT—vF
The talk introduces a novel framework of coded video multicast for
supporting real-time multimedia services such as scheduled IPTV. The talk
will firstly give an overview of the proposed coded video multicast
framework, which is comprised of an intelligent interplay of Multiple
Description Coding (MDC) on Successively Refinable (SR) information source
with Superposition Coding (SPC) based layered modulation at the channel.
For easy implementation of SPC, the talk will introduce a novel Logical
SPC modulation/demodulation technique, which can completely avoid the use
of hardware-based signal superposition and Signal-Interference
Cancellation (SIC) based demodulation. An optimization approach under the
proposed framework will be demonstrated for minimizing the information
distortion at the receiver through dynamic power allocation.

Dr. Pin-Han Ho received his B.Sc. and M.Sc. degree from the Electrical
Engineering department in National Taiwan University in 1993 and 1995,
respectively, and Ph.D. degree from Queenfs University at Kingston at
2002. He is now an associate professor in the department of Electrical and
Computer Engineering, University of Waterloo, Canada. Professor Pin-Han Ho
is the author/co-author of more than 150 refereed technical papers,
several book chapters, and the co-author of a book on optical networking
and survivability. His current research interests cover a wide range of
topics in broadband wired and wireless communication networks, including
survivable network design, wireless Metropolitan Area Networks such as
IEEE 802.16 networks, Fiber-Wireless (FIWI) network integration, and
network security. He is the recipient of Distinguished Research Excellent
Award in the ECE department of U of Waterloo, Early Researcher Award
(Premier Research Excellence Award) in 2005, the Best Paper Award in
SPECTS'02, ICC'05 Optical Networking Symposium, and ICC'07 Security and
Wireless Communications symposium, and the Outstanding Paper Award in
HPSR'02.
