Television Production And Broadcasting Program Data Transmission Network Design

Because the numerical technique, network technique, the software technique...etc. fly to develop soon, bringing the development of the television medium rare opportunity. The television station turns a pleased person of the aspect result in the numeral, and is programing a target by realization at the steady development. The numeral shoots to record, not the line editor system, numerical conjecture play to sow room, numeral to turn to sow a car, the total amount word to broadcast the system, the calculator multimedia creation system automatically to use increasingly and extensively.For the sake of the exaltation of the program creation quantity, quality, efficiency and broadcast a way of excellent turn, south television station the parts of column eyes set up the program creation network, and carry on numeral to turn a reformation towards broadcasting system. The program create net from the devotion use, revolved to raise news a creation the efficiency and quality normally and effectively. Because the history inherit of reason, up to now south television station each kind of column eyes still needs to be download to the top of the videotape to deliver again to broadcast after creating the top of the net to edit completion. The television station broadcast engine room to have already adopted hard drive to broadcast system currently, broadcasting to take in hand over to broadcast the engine room the empress the demand again afresh the top carry to the hard drive of broadcast the server by so doing. After increasing news also expect to edit and broadcast the personnel's work pressure, safety lowered to broadcast normally.This text broadcasts the conjunction project of the system to commence from the program creation network and the hard drive, inquirying into the numerical video frequency network three kinds of work modes for link: Conduct and actions of adopt the magnetic tape lies quality to deliver a data, adopting to flow a way to deliver data and adoption the document method to deliver a data. Between the different video frequency network with turn to lie quality in the magnetic tape conduct and actions. The program that broadcasts engine room and will deliver broadcasts to take up carry to the hard drive to broadcast in the server, prepare catalogue to save to used for broadcast, the program backup system or the medium property management system the magnetic tape information again the data turn. The way transmission data that the adoption flow.? In this kind of work method, up spread work station is an in the network contain the card work station, can return to put to edit a finished program a slice.This paper described three interaction types of digital video network. Interacting by magnetic tape, by media stream and by files. We analyzed the advantages and shortages of this three interaction types of digital video network, then conclude that interacting by files is the best way in this three types. We also analyzed the problems we must face when we use this method interacting in digital video networks, and gave the solutions. This paper gave an exercisable project about interaction by files type in digital video networks, and described this method implements in other fields, just like programs upload system, satellite transmission and so on.
