The Design And Implementation Of Client Of The Multi-point Video Conference System

As the development of network technology, multimedia technology and communication technology, text and voice communication can not meet people's requirement any more, so the development and application of video conference have became one hot spot of the network application. Video conference system is a communication system which uses the network to transmit sequential pictures, audio and data to many participants. Through this system, people in different places can communicate with each other freely and effectively.In this paper, I plan to achieve a small, multi-point video conferencing system as the goal, firstly we introduced video conferencing history and current situation component, classification and etc, and clearly the main content of this article, subsequently I analyzed and studied the key technologies which were related to achieve the system, such as DirectShow technology, network technology and etc, next I divided the function modules according to the actual demands on the system and designed the overall structure and business processes, then I designed video processing module, login and register module, online list and text chat module in detail and achieved the system by coding,wo also tested the program after coding.Finally, I summarized and prospected the system, analyzed some features of this system and areas for improvement, and indicate the technologies used for improvement.
