Developing computer technology provides a great opportunity to develop multimedia product over the Internet. An iterative Teleconference system is one of the most important applications, which has been widely used all over the world. Due to the characteristics of the Internet, it is difficult to guarantee the Quality of Service (QoS) when such a system is used on the Internet. Burstiness, synchronization among Audio and Video, and the reduced Internet bandwidth especially across national boundaries are the most important factors, which seriously may degrade the QoS. As an integrated solution for all these three problems, the SmartChannel was designed and implemented in this paper.
