基于IPTV的交互式E-Learning系统的研究和设计

Research and design of interactive E-Learning system based on IPTV

IPTV作为基于宽带网络的突破性的视频服务应用系统,具有良好的发展前景,特别是在远程教育应用方面。广泛拥有的TV设备和巨大的潜在用户群,使得基于IPTV的E-Learning系统成为颇具吸引力的服务系统。特别是我国农村地区,普遍缺乏足够的电脑,对于传统的基于web的远程教育,受益不大。但是,IPTV用于远程教育,又会带来新的问题,从服务架构到传输内容,都不同于传统的基于web的远程教育系统。在IPTV平台上,如何构建一个E-Learning的系统,并把基于web的学习资源转移到此IPTV平台,需要考虑多方面的因素,本文提出了构建这样一个系统的方法,讨论了其中几个核心的问题。

IPTV based E-Learning is an attractive and promising service for the widespread of TV devices and potential consumers.Especially in rural area in China,it is more useful than traditional web-based learning application for the lack of computers.However,the transition from traditional web-based Learning system to IPTV-based learning is not trivial for the great differences between them.It is a challenge task to design an IPTV oriented E-Learning system and deliver web-based learning resources to the new IPTV platform.In this paper we study the learning process on IPTV platform and present the design methodology of an interactive IPTV-based E-Learning system.Several critical issues have been investigated carefully.
