基于Flex的网络电视互动平台的设计与实现

Design and Implementation of a Flex-Based Interactive Network TV Platform

本文针对现在的网络电视单一的业务模式和功能,提出了建立互动网络电视需要。分析Flex Builder开发平台的特点,介绍了Flex技术的优越性。采用基于Flex的互动网络电视系统,该系统具有很好的可维护性和可扩展性,可方便地实现组件的复用、组装。详细介绍了系统的总体架构设计以及功能模块设计,并重点介绍了系统设计与实现中的难点问题,如实现点对点视频通信、房间管理应对大规模用户访问等等,并详细说明解决问题的设计和实现方法。互动平台的实现为网络电视的发展提供了一种新思路,是传统网络电视在功能方式上的一种衍生,同时它也可能为网络电视行业孕育新的赢利模式。

As for the network television business model and a single function nowadays, this article proposes the needs of establishing an interactive network TV. This article analyzes the characteristics of the Flex Builder development platform, introduces the advantages of using the Flex technology. A Flexbased interactive Web TV system,which has good maintainability and scalability, can easily reuse the components and assembly. What is more, this article details the overall architecture of the system design and the module design, and focuses on the system design and the implementation of difficult issues, such as point-to-point video communication, room management response to large-scale user access, etc. , and details instructions to resolve the problems of design and implementation methods. The realization of the interactive platform for the development of network television provides a new way of thinking, and it is the traditional network TV on the function of a derivative way at the same time. Meanwhile, it will also probably create a new profit pattern for the network TV industry.
