    随着计算机网络技术和多媒体技术的飞速发展，网络教学已成了人们学习知识的新型教学模式，学校对网络课件的需求相应增多。多媒体课件以其美观、交互性较好已成为课件设计的主流。因此设计与制作多媒体课件对网络教学的推进与普及有着较强的现实意义。本文首先对传统多媒体课件与网络多媒体课件进行分析，探讨传统多媒体课件与网络多媒体课件的特点，提出了一个基于模板的网络多媒体课件制作系统的构想。 系统着重讨论了一种应用SMIL语言设计课件模板的方法。所设计出来的课件模板最显著的特点是信息的描述与信息的处理相分离。模板本身只是定义了各个多媒体文件在播放时的时间、空间、传输流量上的布局，而内容的处理和显示则交由Web服务器完成，将信息和对信息的处理隔离开来，使得多方来源的多媒体信息可以完全整合,体现了SMIL语言的优势。网络多媒体课件需要引用大量的多媒体素材，本文对多媒体素材的创作与处理进行了深入的研究，针对不同的多媒体给出了不同的处理方法。系统的开发采用Microsoft推出的IIS + ASP + Access的解决方案，并采用流媒体技术初步实现了一个实用的开放式网络多媒体课件制作系统。该系统融课件管理与素材管理于一体，教师能利用SMIL语言所设计的课件模板，快速生成网络多媒体课件，辅助课堂授课，能统一管理校园网上的教学素材与课件，从而推进校园数字化进程。 [英文摘要]：     With the rapid development of multimedia technology and the computer network technology, the network teaching and learning has become a new teaching and learning mode for people to learn knowledge, the school’s network courseware corresponding increase in demand. The multimedia courseware, with beautiful interactive courseware and good design has become mainstream of courseware design. Therefore Multimedia Courseware Design and fabrication of network and promoting universal education are highly realistic significance.     Firstly this paper introduces the traditional multimedia courseware and network multimedia courseware, explore characteristics of  multimedia courseware and  multimedia courseware of network, proposed a concept of template-based network multimedia courseware production system. The system focused on the application of SMIL language courseware design template method. The courseware designed by the template most notable feature is the description of the information and information processing phase separation. Only template itself defines various multimedia files in the broadcast time, space, bandwidth on the layout and its content processing and display is completed by the Web server, information and the processing of information in isolation from, making multimedia information from multiple sources can be fully integrated, embodies the SMIL language advantage.Network multimedia courseware to invoke a lot of media material, using streaming media technology, the paper do at processing and the creation of media material in-depth study, different media are given different treatment.
