英语听力流媒体点播系统设计

摘要

The use of on demand system for English listening learning is an open learning method which enriches the English learning mode. Based on the technology of streaming media, this paper provides technical support for the development of software. The design includes three aspects: First, the design of the system structure composed of the integrated service platform, the exchange route network and the user terminal;Second is the design of function in the system, including the front desk subsystem and the backstage management subsystem; Third, the design of the on-demand process, through the timing diagram shows the complete process, and the modules are described. The research content of this paper solves the key technology of the software development. The developed media player software has the characteristics of simple, smooth, high quality of picture and has expanded the English multimedia digital learning way.%运用点播系统进行英语听力学习，是一种开放的学习方法，丰富了英语学习模式。本文基于流媒体技术展开研究，为软件开发提供技术支持。设计主要内容包括三个方面：一是，设计由综合服务平台、交换路由网络和用户终端构成的系统结构；二是，设计系统功能，包括前台点播子系统和后台管理子系统；三是，设计点播流程，通过时序图表明了完整的处理过程，并对各模块进行了说明。本文的研究内容解决了软件开发关键性的技术问题，开发出的媒体播放软件具有简洁、流畅、画面质量高等特点，拓展了英语多媒体数字化学习途径。
