视频点播系统的设计与实现
摘 要
随着计算机技术和 Internet 的日新月异,宽带 VOD 视频点播技术因其良好
的人机交互性和流媒体传输技术倍受教育、娱乐等行业青睐。本文阐述了基于
WEB 的交互式视频点播系统的协议原理、软件结构和设计实现。
本视频点播系统根据流媒体传输原理，在校园局域网的基础上模拟基于
Web 的视频点播系统，实现用户信息管理、视频文件的添加、删除、修改及在
线播放和搜索功能。本系统是一个小型系统，我们采用基本的 SQL Server 数据
库。具体实现中将 HTML、ASP.net 及 C#相结合，力求界面美观、操作流畅。
本文主要论述服务器端视频服务平台的搭建、流媒体的相关原理及管理功能
的具体实现。
关键词：流媒体；ASP.net；视频点播
Video on demand design and implement
Abstract
Broadband VOD (video on demand technology) get the favour of profession
such as education and amusement because of its good human-computer interaction
and streaming media transmission technic. In this paper, I elaborate systematic
principle of the protocol, software structure and design implement based on Web
interactive video on demand.
According to the streaming media transmission principle, this video on demand
system imitates video on demand system based on the Web, implement that users’
information management and the functions of adding, deleting and modifying, online
playing and searching for video files on the basic upper local area network of the
campus. Since this system is a small-sized system, we use the basic SQL database. In
specific implement, I fuse HTML, ASP.net and C# perfectly, try my best to make the
interface beautiful, operate smoothly.
This paper discuss mainly about the video service platform building, the related
principle of streaming media and the specific implement of management function.
Key words: Streaming media; ASP.net; video on demand
