| Summary: | 碩士 === 國立成功大學 === 工程科學系碩博士班 === 94 === Video conference systems have become a very important application on the internet at the present day. The Access Grid developed by National Argon Laboratory is an open source system which integrated with video, audio, and many sharing applications such as shared power points, browsers, and becomes a popular internet communication platform. Access Grid can provide better quality both in video and audio than that of conventional video conference systems. On the other hand, Access Grid is a group-to-group video conference system which was built using Grid technology. Unfortunately, there is no mechanism which can control the progress of the conference. To improve this disadvantage, a conference control module was designed and some shared applications and node services are added into the Access Grid to extend its functionalities. A typical application for collaborative scientific visualization conference by using the designed conference control module to discuss the interested subject on the internet was shown.
