| Transmitting video over low-bandwidth,
high-error channels, such as between cell phones, is a challenging
task. Although we will see video transmission in the next generation of
wireless standards, there is still
work to be done to ensure high-quality transmission.We will examine some
of these problems, look at the current video transmission standards, and
discuss the challenges in source and channel coding for video. A method
of modeling the effects of degradation in video will be introduced and its
use in joint source-channel coding schemes discussed.

Science, a B.S. in Communications, an M.S. in Electrical Engineering,
an M.S. in Mathematics and a Ph.D. in Electrical Engineering all from
Rensselaer Polytechnic Institute. She has been an Assistant Professor
in the Electrical and Computer Engineering Department of Drexel University
since 1997. Her areas of interest are image/signal processing for communications,
joint source-channel coding, and optical communications. Recent awards
include a 2001 Fulbright Award and an NSF CAREER Award in 1999.
