传统的会议总是需要先预定时间、地点,统一开会人员及布置会场、记录、主持等，会议所要解决的问题或是要制定的方案、决策常常由于许多客观因素而耽搁。视频会议（VideoConference）系统是一种能把声音、图像、文本等多种信息从一个地方传送到另一个地方的通信系统，它解决了以上的问题,免去论文范文http://www.chuibin.com/ 了很多会议开支,缩短了解决问题的周期,使客观因素的影响大大减小。视频会议系统作为计算机技术和通信技术相结合的产物，正随着波及全球的信息高速公路的兴起而迅速发展起来。本文介绍了视频会议系统的基本概念,与其相关的Java媒体框架（JMF：Java Media Framework）和计算机支持的协同工作（CSCW：Computer Supported Cooperative Work）系统，Java语言及其开发环境，并根据视频会议系统的基本结构和一些相关技术，说明了一个基于JavaGroups工具包的小型视频会议系统的设计和实现。

Abstract
Traditionally,holding a conference needs some complex procedures for a long time ,such as pre-arranging the schedule ,place ,people ,preparing
the hall ,recorder ,master and so on. The goal of a meeting , resolving problems or making plans and decisions ,will be usually delayed by such
objective factors. The video conference system is a communication system
that transmits many kinds of signals such as video, audio, text and so on from one place to another. It is created to save money and time because of meetings and helps reducing the influence of objective factors. The
video conference system is the combination of computer technology and
communication technology, and it is now developing very fast with the National Information Infrastructure of the whole world. This article introduces the basic concepts of the video conference ,JMF(Java Media Framework) and the CSCW (Computer Supported Coorperative Work)system and Java language. According to the basic structure of video conference and some other technology,it describes the design and implementation of a mini-video conference system based-on JavaGroups toolkit.
