数字广播远程教育系统的客户端软件设计方案

The Project for a New Client Software about Remote Teaching Based on Data Broadcast

提出了基于数字广播技术来实现的远程教育客户端软件的整体设计方案.该系统软件的所有的用户界面都是基于IE浏览器的网页界面,所有的客户端操作处理模块都设计成IE浏览器的插件.文中还着重论述了客户端软件中对已经下载到本地主机上的课件的自动管理、客户端的实时视音频播放、远程课堂答疑等诸多问题.文中也论述了三网合一技术在本系统中的应用实现原理.用户使用该软件就像在浏览IE页面一样,因此一般用户不需专门培训就可以很方便地使用本软件.

The project for a new client software about remote teaching ,based on Data Broadcast were proposed. The interface of this client software is basing on IEbrowser ,and all modules of the software are designed to the Plug-in in IEbrowser. In this paper some problems, for example the automatically managing teachingfile and realitying the interface inlayed in IEBrowser and remote classroom instruction and so on, have been introduced with emphasis . Using this software ,the client like to use the browser ,so for most of the client, the special training is not necessary to apply this software.
