项目摘要

In this research, we consolidated a multipoint video conference control system which can connect various types of communication standards, we then tested the connections of the interactive multipoint video conference system using ground communication networks and satellite communication systems.(1)Experimental test of interconnection of various communication protocols.We demonstrated the following experimentations.【1!○】 Maintenance of video conference attachment unit which can correspond to multipoint, multiprotocol, and multi speed【2!○】 Multi speed connection such as 2B/4B/6B with ISDN line【3!○】 Connection of video conference software for personal computer which uses IP connection【4!○】 Multiprotocol connection by IP and ISDN connection【5!○】 Live streaming and VOD notice assignment by connection of video conference and video streaming device【6!○】 Connection of video conference device with different models【7!○】 Practical use of connection with video conference with satellite lines such as SCS and el-net【8!○】 Simultaneous connection of SCS-LAN connection-ISDN connection-el-net(2)Trial and consideration of various distance cooperation lectures.We have improved the environment for comprehensive distance lectures through the interconnection of the systems and then have administrated this system to the distance collaboration lecture and such on a trial basis.As a result, we could compile the problems of the system, and their solutions for implementing distance lectures and the know-how for its operation.In addition, we examined the distance learning model in which we made positive use of the functions of the collaboration lecture system.

在本研究中，我们整合了一个多点视频会议控制系统，可以连接各种类型的通信标准，然后我们测试了交互式多点视频会议系统使用地面通信网络和卫星通信系统的连接。（1）各种通信协议互连的实验测试。一！○]可对应多点、多协议、多速率的视频会议附件单元的维护[2！○]多速连接，如2B/4 B/6 B与ISDN线路[3！○]使用IP连接的个人计算机的视频会议软件的连接[4！○]通过IP和ISDN连接的多协议连接[5！○]通过连接视频会议和视频流设备进行直播和VOD通知分配[6！○]视频会议设备与不同型号的连接[7！○]通过卫星线路（如SCS和el-net）与视频会议连接的实际使用[8！○] SCS-LAN连接-ISDN连接-el-net的同时连接（2）各种远程合作讲座的试验和考虑。通过系统的互连改善了综合远程讲座的环境，然后在试验的基础上将该系统管理到远程合作讲座等。结果，我们可以编辑系统的问题，以及实施远程授课的解决方案和操作技巧。此外，我们还对积极利用协作授课系统功能的远程教学模式进行了研究。
