Design And Implementation Of Online Video On Demand System Based On Javabean

This paper analyzes the Internet video streaming, builds a film and television broadcast system based on computer network. The paper explains the running environment, composition and related applicable technology of film and television broadcast system under the network environment, elaborating both overall and detailed designing. On these bases, it uses the technologies related to system development such as browser/server structure, JAVA technology, database to realize the system main function.This system is an online video-on-demand system based on B/S structure, and its purpose is to improve the sharing of film and television resources. The system adopts B/S structure in order to makes it unnecessary for users to install the the client, instead they only need a browser. The separation of development environment and application environment, improves the scalability, security and reusability of the system.Alterations in the structure of database will not lead to chain effect for the client,which improves the maintenance efficiency of the system.Video-on-demand system, which uses unlimited space of network, allows users to watch films anywhere at any time, expanding the flexibility of watching films.Coupled with the use of network database technology, the system greatly simplifies the process of traditional film and television playing.Investigation has been done for the situation of the information management in video-on-demand today, analyzing the important significance of building online video-on-demand system based on network technology. It analyzes the current network system of the B/S structure, using JAVA frame structure mode to the whole system structure; introduces the technical characteristics in detail, and analyzes the realization of JAVA development system. Based on the Internet B/S framework the system adopts B/S structure mode, it greatly saved funds and costs in development and maintenance. The feasibility of the system are analyzed in detail in the paper,confirming the feasibility of the hardware, technique, maintenance of the system. This paper also summarizes the detailed business, functional and performance requirements of the online video information management system.The system development process is based on the analysis of demands, adoptsmodular design thought, the role and function of the system in detail, has been clear about the user interactive features, and has carried on the design of each function module, the system of the key functional modules are carried on the detailed introduction.The system mainly includes user module, the film module, integrated query module, video-on-demand, and other function modules. The main features of the system are: using the Internet, film and television broadcast system can give full play to the role of the film, and to make the fans to view the latest online excellent films timely, comprehensively and conveniently.
