Design And Implementation Of The Entire TV Station Network's Data Collection System

Network media has been widely used in social life in the new period.As an important entertainment choice for people nowadays,the system design and operation of broadcasting and TV need to keep pace with The Times,to realize digital and networking,and also to be constantly improved.In recent years,the whole network system of television has been gradually used in society,since the system can realize automation,digitization as well as networking,provide users with high working efficiency and reduce the cost of capital,therefore,it gradually occupies the social market.Is the networked,digitalized platform with audio and video as the main body.System can realize the features as material acquisition,production,storage,broadcast,sharing,etc.,and can collect the data flow of optical fiber network,satellite signal,cable TV,Internet,video and audio signals from multiple sources as well as the centralized control.Thus,the refinement of management,the optimization methods of production and the most effective resources integration can be realized.Although the system used of in current market system has basic functions,but with the development of society and economy,it can't satisfy the requirement of rapid development television network system any longer.The system that this paper explores will improve the stability,comprehensiveness,high efficiency and safety through the design and analysis of the modular.In order to ensure the normal function of the core modules,this system acquisition system adopts pre-allocated design concepts,and the acquisition modules are autonomous systems,therefore,even in the case of network anomalies,the system can still run normally as well as reducing the number of television accidents.At the same time,the system adopts the total control and each client's asynchronous non-blocking communication mode to realize real-time interaction of the system.Through main task,total control,first-local-second-network and the double-reading mechanism to provide guarantee for system security performance.The system can also automatically restart and return to normal even in abnormal situation.Even with the external system connectivity and with a third party,it also can show its openness and extensibility.This paper introduces the research background,and make a summary about the performance of the network of the whole television station,needs analysis,implementation as well as testing.Meanwhile,all the specific module design and implementation are described in detail,and have been tested.With high security,strong real-time performance,and the external system connectivity,this system can solve many practical problems,improve the efficiency of the television,and can meet the needs of the development of the current market.In combination with the current development trend of radio and television,we prospected the future development in the system.
