The Design And Implementation Of A New Generation Hard-disk Broadcasting System

Broadcasting technology is a product of technological revolution. With the rapid development of science and technology, digital broadcasting began. After the emergence of internet technology, computer technology has entered a new stage. Original automatic broadcast system is the start-up and switch controlled by computer-controlled equipment. Combined with computer network technology, form a new hard drive based digital broadcast video server system.Research on the Shenyang TV station broadcasting old system, combined with computer network technology, based on the actual situation of Shenyang TV station, the first generation of digital hard disk broadcasting system was upgraded, modified. The new generation hard-disk digital broadcast systems connect to the media resources network. So that to achieve the Interconnection of the network programming, media resource network, advertising network and broadcast network. And achieve the broadcasting without a tap and broadcasting in network. This broadcasting system is the real full-disk broadcasting system.The first, the paper describes the digital television and digital television broadcasting system.The second, describes and analysis the key technologies of digital hard disk broadcasting system construction. The third describes the design ideas and specific implementations of the new generation hard-disk broadcasting system. Among them, including the system hardware design, the functional design of software system, the network architecture design of the system of broadcasting and control, video server comparison and selection, the design of the total control system.The fourth is the specific situation of the project implementation. Finally, make an analysis and summary for the new generation of hard-disk broadcasting system design and implementation.
