基于C＋＋的视频会议系统的设计与实现

摘要

In recent years, the Chinese video and audio communications market is growing mature, the video conferencing can cross spatial distance and provide flexible and diverse face-to-face interaction, and adapts to the demands of modern society in convenience, quickness and efficiency, these requirements need better services provided by the video conferencing systems.In our design, we mainly study the way to achieve the dual functions with both the text chat and video chat through Socket and Direct using C/S software model as the basis and in compliance with H.323 and SIP protocol as well as based on the text chat, the focus is put on the solution of permission problem of conference users, so that the means of two terminal co-management for meetings is adopted, the managing user of the conference room can execute meeting management and monitoring through conference management terminal, while the users participating in the conference can join the meeting through client terminals.%近年来，中国视音频通信市场逐渐成熟起来，视频会议可以跨越空间距离，提供灵活多样的面对面的交互，适应现代社会的方便、快捷、高效的要求，这些需要视频会议系统提供更好的服务。研究在文本聊天的基础上，以C／S的软件模型为基础，按照H．323协议和SIP协议，通过Socket和Direct做到兼顾文字聊天和视频聊天的双重功能，重点在于会议用户权限问题的解决方案，所以采用两个终端共同管理会议的方式，会议室管理用户可以通过会议管理终端进行会议管理和监控，参与会议的用户可以通过会议客户终端加入到会议中。
