一种基于组播并支持多接入方式的IP网视频会议系统的设计和实现

Design and Implementation of the Multi-access Video Conference System Based on IP Multicast

设计并实现了一种定位于公共IP网的视频会议系统。该系统支持多种网络接入方式,利用组播模式进行数据传输,客户机-服务器的工作模式。针对会议系统的各个组成模块,均给出具体的设计模式和实现手法;对核心的音视频压缩编码部分,提供独特的优化策略以及具体的性能参数。

In this paper,the design and implementation of a video conference system over IP public network is intro-duced.This system puts forward multi-access managements,data transferring based on IP multicast and client-server model.For all main modules of the system,the design patterns and the techniques needed to implement them are pro-vided.For the compression and encoding of audio and video data,specific optimizing strategies are applied and the pa-rameters of its performance are given in detail.
