Interactive Multimedia Education at Distance over Asia Using High Speed Internet Satellite

在目前的研究方案中，我们提出了以下新的框架：一是呼吁消除亚洲教育领域的数字鸿沟；二是建立新的21世纪科技教育体系；CENTURY，C，为亚洲大学网络的高效建设做出了贡献。(1)建立了模拟WINDS的卫星网络系统，以了解网状和频带共享环境下电子学习平台的需求。(2)建立多点远程学习系统在(1)卫星网络系统下，我们通过实现KDDI开发的远程学习IP应用软件来构建一个多点远程学习系统。当我们在卫星网络系统下使用IP应用时，由于卫星链路造成的时延或不同站点之间的负载不平衡，由于卫星网络系统的特点，很难获得统一的网络资源和质量，因此会出现许多问题。在卫星网络系统的基础上，构建了教育门户系统LMS(学习管理系统)，并在此基础上开发了相应的教学软件。本财年，我们还在泰国和马来西亚进行了天线建设的试验并取得了成功。我们还成功地通过了泰语/马来西亚；-日本和日本&lt；-&>泰语/马来西亚流媒体的网络测试。

In the present research proposal, we propose the following new frameworks to a, call for the elimination of Asian digital divide in educations ; and b, establish new educational system for 21^<st> century, c, contribute to the efficient construction of Asian university network.(1)Building satellite network system emulating WINDSWe have build a WIND-emulation network system in order to understand the requirements of e-learning platform under both mesh-type and band-sharing environments.(2)Building multi-points distant learning systemUnder the satellite network system in (1), we construct a multi-point distant learning system by implementing distant learning IP application software entitled"Sky-Cast Lesson"developed by KDDI.When we use IP application under satellite network system, due to the time-delay caused by satellite link or the load-imbalance between different sites, it is difficult to obtain a uniform network resource and qualities and thus numerous problems will occur by the characteristics of satellite network systems. Sky-cast lesson can provide a stable pilot experimental platform with ease because it is implemented as the satellite network system.In addition to this system environment, the LMS (Learning Management System) that is the portal system for education are constructed and we develop some courseware under the system. This fiscal year, we also experimented and succeed in the antennas construction in Thai and Malaysia. We also succeeded in network tests of Thai/Malaysia<-> Japan, and Japan<->Thai/Malaysia streaming.
