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.

本研究整合了一个能够连接多种通信标准的多点视频会议控制系统，并利用地面通信网络和卫星通信系统对交互式多点视频会议系统的连接进行了测试。我们演示了以下实验。【1！○】视频会议附件单元的维护，可对应多点、多协议、多速率【2！○】具有ISDN的2B/4B/6B等多速率连接线【3!○】连接使用 IP 连接的个人计算机视频会议软件【4!○】通过 IP 和 ISDN 连接进行多协议连接【5!○】通过视频会议和视频流设备的连接进行实时流媒体和 VOD 通知分配【6!○】不同型号视频会议设备的连接【7!○】通过SCS、el-net等卫星线路进行视频会议连接的实际使用【8!○】 SCS-LAN连接-ISDN的同时连接connection-el-net(2)各种远程协作讲座的尝试和思考。我们通过系统的互联，改善了综合远程讲座的环境，然后将该系统试用于远程协作讲座等。由此，我们整理出了系统存在的问题、实施远程授课的解决方案以及操作技巧。此外，我们还研究了积极利用协作功能的远程学习模式。讲座制度。
