摘要
为了发挥多媒体教学技术在教学中的高交互性和平稳性特点,提出研究英语听说能力的多媒体远程教学系统。在交互性方面,运用互联网资源、三层浏览器/服务器体系架构与流媒体技术,构建拥有多子系统的远程教学系统,并将设计系统客户端优化处理,使之交互性增强;在平稳性方面,使用分级网络编码方法,计算延时均值,保障系统数据包的稳定传输。测试结果表明,提出的多媒体远程教学系统网络传输稳定性良好,软件运行流畅清晰,有较高的应用价值。
In order to give full play to the high interactivity and stability of multimedia teaching technology in teaching,this paper puts forward a multimedia distance teaching method to study the training of English listening and speaking ability.In terms of interactivity,it uses Internet resources,three-tier browser/server architecture and streaming media technology to build a distance learning system with multiple subsystems;in terms of stability,it uses hierarchical network coding method to ensure the stable transmission of system data packets.The test results show that the proposed multimedia distance teaching method system has good network transmission stability,smooth and clear software operation,and has high application value.
