And with the constant improvement of work information, online video with its film and television viewing has changed the traditional way, without any restrictions, the advantages of signing up more and more popular with users of the love and attention. With the continuous development of work technology, video on demand has developed since the 20th century 90 years, it is based on the original text, images and other static information visit , add with the dynamic view video and audio multimedia ondemand service. Online video on demand system is just a information management system to provide this service with dynamic interactivity, which implements an Inter online theater. Users can view video messages online and broadcast programs according to their preferences. In this way, users can watch movies without leaving home, can browse the Web at anytime, anywhere, and free from the limitations of traditional television viewing time and resource limitations of the traditional CD player, the lives of people work has greatly enriched. With the rapid rise of the Inter, B / S structure of the system bees more and more prevalent, B / S structure of the system can be installed on any one puter with browser to use, the deployment and maintain of the system can do just on the server. This model will reduce management costs, more importantly, it is very easy to implement user interaction with the system, faster response to user39。s demand to submit the request. This paper introduced the design and implement of an online video on demand system, which based on the B/S structure. The system is developed in bined with C, to achieve dynamic interaction with the user and to meet the needs of users.
