Television Program Content Review System Design And Realization

With the rapid development of network and digital technology, computer network has been widely used in the television, network has brought us convenience and shortcut hitherto unknown. In digital television, network, file-oriented environment, the traditional trial-chip can not meet the development of production and broadcast workflow. Therefore, the establishment of a large environment with adaptation, networking and file-based content review of the film system is imperative.The main work in is included as followed:(1)Analysis the domestic research on television review system, the architecture television review system and operation mode are introduced; the key technology used in the system is analyzed and described the program content, including audio and video codec technology, data transmission technology, digital rights management technology and distributed transcoding technology etc.(2) The function demand, performance demand and the interface need are analyzed by the demand of content review system from, and the scope of business, business role and responsibility system parameters are discussed, on the basis of summarizing the system structure was given to, completed the overall design of the system.(3) The key part of the system detail design and implementation is included: business model design, design and implementation of model design, the system design and application platform, focus on the design of foundation platform.(4) The content review system application environment, and then presents the application effects of the system of STB and PC terminal use effect, verified the effectiveness of the system.In this thesis, design and Realization of television program content review system using a combination of video and audio file encoding and decoding technology and data transmission technology, which improves the security review system, but also enhances the usability of system operation. The system provides an effective technical means for the realization of the system network, documented.
