Research On The Design And Application Of Live Video System Based On Campus Network

21st Century is the information-based ages. The tidal wave of the information technology application, which was with the core of Multimedia Computer Internet, not only has brought a great impact on the modern education, but also has injected new vitality.The application of the Computer Information Network has broken the traditional education on thinking, means, content, course and the organization by providing teachers and students with the network multimedia courseware, information exchange platform, emulational educational system, and education resource sharing, etc. The campus network,which is the general platform that connects to the CERNET, has already made a great contribution to the exchange and management of the information and sharing the teaching resources of the high school.The thesis tries to focus on the design and the actualization of the live video system based on the campus net. The main work is listed as follows:First of all, the thesis will elaborate the concept and the service functions of the campus network and the concept of digital campus.Up to now, the Streaming Media Transmission Technology is one of the important technologies for the video-audio data in the network transmission. So the thesis researches the Streaming Media on its concept, application, system buildup, transmission theory, transmission agreement, file format and platform. Moreover, it also more particularly analyzes its various transmission mode unicast, broadcast and multicast.Then, by giving the example of Wuyi University's buildup the live video system based on the campus network, the thesis study on the problem of the design and the actualization of the live video system based on the campus network. It concretely construes the situation of Wuyi University's campus network, and comes to a conclusion of the design programming of the live video system based on the campus network. It construes the application need of the equipment, including digital video camera, digital eidt tape recorder, video non-linear edit computer, video live workstation, video promulgating server, etc. It designs the reasonable project based on the live video system of the campus network. At the same time, it concretely comes to the topologic-drawing which is based on the live video system, the system equipment parameter, and system setting. It establishes the actualization system based on the need. Simultaneity, the essay analyzes the problems found in the system running, and then...
