| 摘 要： | 介绍了一种基于SIP协议的网络可视电话的原理和实现方案.这种网络可视电话,利用SIP以及相关的SDP,RTP等开放性协议,完成了通讯双方实时的语音和视频信息的交互,既可以应用到即时通讯方面,也可以作为视频会议实现的基础.同时,遵循开放协议,使得整个系统有着很好的兼容性.本文首先介绍了整个系统基于SIP所采取的框架结构,随后介绍了会话初始协议SIP,以及相关的会话描述协议SDP,最后讨论了系统实现的主要任务和设计方案.

| Abstract: | Introduced in this paper is theory and implementation of internet visual phone based on SIP protocol. This type of net visual phone is implemented based on open protocol including SIP, SDP and RTP etc. in order to fulfill instant information exchange of audio and video stream. It can be applied not only to IM, but to video conference. Meanwhile it is more compatible since of foundation of open protocol. We first introduces whole system structure, and then simply introduces SIP and SDP protocols, at end of this paper, we discusses basic functions that are supposed to be implemented and the way we put them into reality. |
