摘要:本系统开发采用ASP.NET编程语言，以Visual Studio 2005、SQL Server 2000为开发工具，Windows XP作为操作系统而实现。采用流媒体技术和ASP.NET技术实现了视频在线点播、在线直播、视频投票、视频检索、视频评论、后台管理视频、后台管理评论、数据库管理等主要功能，其中用到大量逻辑算法与思维，比如视频搜索，为了实现复合条件搜索功能，其中参数的传递就进行了30多种排序，其中视频点播功能和视频直播功能用了流媒体技术，使用户访问时实现实时传输的效果，通过本系统的设计与实现满足了用户的需求，同时方便了用户对视频资源的访问要求。

　　　当今社会是信息社会，计算机信息管理领域的竞争十分激烈。尤其是我国加入WTO以后，计算机信息管理领域的竞争就更激烈了。在全球化、网络化、信息化、数字化趋势下，快速成长是中国企业的典型特征， VOD(VideoOnDemand)的实质是信息的使用者可根据自己的需要主动获得多媒体信息,具有主动性和交互性的特点。最初的VOD应用于卡拉OK点播,以后逐渐应用到局域网和有线电视网中,随着计算机存储技术、网络通信技术和视频压缩技术的高速发展,通过互联网络进行VOD服务已成为可能。而基于Web的实时流媒体VOD系统随着Internet的迅猛发展,将成为人们喜爱的双向交互的A/V实时点播系统。VOD技术是多学科、多领域交叉结合的产物,可应用于政府企事业内部视频资料点播、视频会议、学校远程教育、宽带网视频点播和互联网直播等许多领域。

Abstract:The development of this system using the ASP.NET programming language, Visual Studio 2005, SQL Server 2000as a development tool, Windows XP as the operating system and the realization of. Using streaming media technology and ASP.NET technology to achieve the online video on demand, online live video, video retrieval, voting, video reviews, backstage management, backstage management review, video database management such as the main function, which uses a logic algorithm and thinking, such as video search, in order to realize the composite condition search function, in which parameters are passed on the30 kinds of sorting, in which video on demand function and video broadcast function using streaming media technology, and user access to achieve real-time transmission effect, through the system design and implementation to meet the needs of users, and is convenient for a user to access requirements of video resources.

　　　Today's society is the information society, the computer information management in the field of competition is very intense. Especially after our country joins WTO, computer information management in the field of competition is more intense. In the context of globalization, network, informatization, digitalization, rapid growth of Chinese enterprises are typical features, VOD ( VideoOnDemand ) is the essence of information user can according to their need to take the initiative to obtain multimedia information, active and interactive features. The initial application of VOD in Cara's OK VOD, then gradually applied to the local area network and cable television network, along with the computer storage technology, network communication technology and the rapid development of video compression technology, through the Internet VOD service has become possible. Web based real-time streaming media VOD system with the rapid development of Internet, will become the favorite interactive A / V VOD system. VOD technology is a multidisciplinary field, cross combination, and can be used for government enterprises internal video on demand, video conferencing, distance education, school broadband VOD and live Internet and many other fields.
