| With the rapid development of the Internet and digital media technology, video-on-demand (VOD) services have become the most widely used Internet application. VOD gradually reveal the huge market potential of its industrial development. With the expanding of video resources and user base, brought geometrically growing data storage and access requests to the server. Video server which has limited data storage capacity and request processing capability, and limited network bandwidth will severely affect quality of service, posed a serious challenge to the availability of VOD services.This paper designs and implements VOD system based on cloud storage, on the basis of VOD system architecture based on cloud storage for the relevant extensions. This system uses cloud storage for hosting platform video resources, the use of cloud storage of massive storage capacity and flexibility stretching capabilities provides storage solutions for VOD system. At the same time, cloud storage is used as Data Center of VOD system, so that users can quickly access video on the cloud through Internet anywhere, and implement playback based on HTTP streaming on client.On the view of application, this paper designs a kind of VOD architecture based on the cloud storage, which combined with basic business processes of VOD systems and cloud storage application characteristics and scenarios. The paper also puts forward the video upload models and access model based on cloud storage, using Java SDK which provided by qiniu cloud storage to develop the VOD system. Meanwhile, the paper implements video playback functions based HTML5technology, users can enjoy the video playing on higher version of the browser on a variety of terminal devices without plug-in, with availability of strong cross-platform.Currently, the VOD system has been applied in the construction of a university information platform, to provide customers with a good VOD services, but also provide a good space for the expansion of video services. |
