摘　　要：随着信息处理技术的不断普及,视频会议系统成为多方可视通信的一种主要方式。以宝鸡第二发电公司为例,全面介绍了视频会议系统的技术实现和应用情况。根据其通信方式,视频会议系统可以分为基于嵌入式架构的硬件实现和基于PC架构的软件实现2种,具有各自的优势和特点。文章详细介绍了视频会议系统所采用的有关通信标准协议,指出H.323协议标准是未来多媒体视讯会议的发展方向。结合实际使用情况,还介绍了视频会议系统的硬件组成和组网经验,并给出了视频会议系统在使用过程中需要注意的问题。With the development of signal processing technique and its application, the Videoconference System （VCS） has become a main visual communication method. Taking Baoji No. 2 Electric Power Plant as an example, this paper introduces the VCS teehnical realization and its application. According to the communication method used, the realization of VCS is divided into two modes, one is the hardware mode based on the embedded architecture and another is the software mode based on the PC architecture, and the two modes have their own advantages and features respectively. This paper introduces and analyzes the standard protocols of VCS communication, and points out that H. 323 protocol will be adopted in the future VCS. Based on the VCS practical use, the hardware composition and the network-construction experience are introduced. Additionally, the problems that need to be adverted while using VCS are given.
