ABSTRACT
The MPEG standard for video coding is widely used in practical
communication systems at many bitrates, from multimedia communications
to HDTV. Although motion compensation is a key element of the MPEG
algorithm,, it is too computationally intensive to be used in real time
video compensation by software.

A novel progressive coding algorithm is therefore developed for a low
cost personal video communications system to real-time video transmission
via the Internet. The codec gives good performance over range of peak
bitrates  from 0.1 bpp to 1 bpp. Over the whole range, the quality of the
reconstructed sequence is significantly better than "motion JPEG," while
the codec is much simpler and faster than MPEG.

Wavelet representation is a powerful processing technique that provides
a multiresolution decomposition of images.  The coding schemes for HDTV
and video phone based on wavelet decomposition will also be presented.

BIOGRAPHY Huijuan Li attended Zhejiang University in China. She received
her BS Degree in Electrical Engineering in 1985,, her MS Degree in 11988
in Communications and Electronic Systems and her Ph.D. in 1993 writing her
dissertation on "Image Compression adn Coding and Filters."  She had a
post-Doctoral Fellowship at the Chonbuk National University in South Korea
form July 1994 - July 1996. From February 1996 to January 1997, she was on
the research staff at Bath University in England studying the Development
of personal video communications system by Software only solution of
real-time video transmission via the Internet.
She is currently working at Wriight State University.
