网络课件编辑制作系统的模型设计与功能实现

本文探讨了网络课件编辑制作系统的设计方法和体系结构。针对目前网络课件共享性差,且制作过程复杂等问题,本文提出了基于XML的网络课件的元数据著录模型和内容包装模型,实现了对远程教育标准的支持,解决了资源共享和数据交换的问题;同时采用基于时间线的多轨道的信息组织方式,使视频、音频、幻灯片、讲稿和目录等内容能够一次性同步合成,简化了课件制作过程,提高了制作效率。

The Model Design and Function Realization of Network Courseware Edit & Producing System

This paper discusses the framework and design method of network courseware Edit & Producing system. In view of the poor share and the complex process of network courseware ,the paper provides network courseware metadata catalog model and content packing model based on Extensible Markup Language (XML),realizes the purpose of supporting the distance education standard ,then solves the problem of resource share and data exchange; and it adopts multi-track information organization based on timeline, can synchronize and integrate video, audio, power point (PPT), lecture and catalog at one time ,simplifies the process of network courseware and improve the efficiency of process.
