中文摘要：

在视频会议系统中，服务器端多媒体数据流的存储转发有其特殊的背景和要求，因而需要一个高性能的多媒体数据流的缓冲机制，该机制的高效与否是制约视频会议系统性能的关键因素之一。在传统的生产者／消费者模型的基础上，结合多媒体业务的特殊环境，提出了一个新的数据流的缓冲机制模型，并在此基础上实现了一套集中式的多点视频会议系统。

英文摘要：

With the rapid development of computer network technology, video conference systems created on the IP-based network are widely adopted in many companies and organizations. Due to the special network environment and requirement of video conference system, the multimedia data dispatching module at the server side has a significant influence on the system performance. Based on the traditional producer/consumer model, this paper presents a new scheme in dispatching the multimedia data at the server , and at last, the implementation of our network video conference system is discussed.
