Objective: An interactive
presentation and transmission of audio, video, graphics, and text have become a
major driving force behind information technology that merges practices of
communication, computing, and information processing into an interdisciplinary
field of multimedia. Internet protocol
(IP) is becoming the common denominator for multimedia services over the
Internet and possibly over the wireless access. However, the Internet and
wireless networks impose some necessary tradeoff between quality of service
guarantee and resources utilization efficiency, for example, the audio and video
transmission must be real-time by videophone. In this course we
will mainly concentrate on video compression and transmission over IP.
Applications that are based on video transmission over IP are becoming more and
more important in our everyday life, e.g.: videophone, video conferencing, video
on demand, distance learning, remote collaboration, and video surveillance.
If transmitted uncompressed, even a low-quality color digital video of 15
frames/s in CIF format (352x288 pixel resolution) requires about 18 Mbit/s.
However, it is possible to compress it below 100 Kbit/s without any noticeable
difference in image quality, which makes it possible to transmit digital videos
in real time over existing networks. This new course will
give an introduction to basic concepts and standards of video compression.
Problems related to transmission of compressed video over IP will be discussed,
and their solutions will be presented. Although video transmission over IP is
present in our everyday life (e.g., there exist a number of commercial systems
for videophone), it still faces many challenges. Prerequisites: CIS 551. The
course will be self-contained and all necessary concepts will be introduced.
Good programming skills in C, C++ or a similar language are important. Required
