Video conference systems allow the people at different office
locations to communicate with each other through video,
voice, and static data such as text, graphics or images.
The idea of video conference systems has been studied for many
years. There are many literature in this field. So far,
most existing video conference systems use dedicated lines to
carry traffic. However, to set up dedicated lines is
expensive in general. If video conference systems can be
developed on local area networks(LANs), the coverage area can
be extended to the users without using dedicated system.
This approach will make video conference systems more
popular. With the increasing power of modern computers and
high speed network technologies, it is possible to develop
video conference systems on LANs. In this thesis, we try to
built a prototype of video conference system with inexpensive
products and explore the factors affecting its performance.
On the other hand, we will analyze the problems of video
conference system over LAN and propose the methods to solve
them.
