| The safety of radio and television broadcast is an important task of TV station.Broadcasting is a juncture of television. The safety, reliability, of broadcasting candirectly affect the watching effect and quality of users. With the rapid development ofcomputer technology, the past rely on manual+video broadcast mode has been fullyreplaced by automatic hard disk broadcast technology. With the whole stationnetwork construction of all kinds of TV stations, It makes the application of hard diskbroadcasting system have more realistic significance. But, how to build aneconomical, safe and stable hard disk broadcasting system is an actual problem foreach television station which are considered.At present, the hard disk broadcasting system has been used by the most TVstations in our country. Each system has their own characteristics. But all focus onsafety and stability. The hard disk broadcasting system of Urumqi television station isalso following the big trend. It is not only greatly Promote the safety and effect ofbroadcasting of Urumqi TV station, but also reduce the labors’ intensity of workingand Laid a solid foundation for the Urumqi TV station ’s long-term development.Hard disk broadcasting system is an independent system that included computerand network technology. From the simple meaning of it, which shows us eachFunction software of the system that through Controlling between the devices tocoordinate the work. To finish he broadcast, upload, monitoring, collection andother tasks. For example: Broadcast control terminal by Local area network send outthe Broadcast instruction to video broadcast server. At the same time, sending theinstruction to Switcher, and then begin to switch. The server of Video broadcastingwill look for the specified material, According to The instructions which are received.Then broadcasting with certain rules. However behind this simple Technologicalprocess, there are lots of other tasks need to be finished, How to design a set ofReasonable software which has Perfect function? It need to detailedly understand every requirement of Broadcast work. This software can bring the performance of thesystem into full play. Broadcast control system software is a unity which is composedby many Function Sub modules. Such as: Material uploaded, Material transfer,Material technology. Material management, and so on. It needs close contactbetween these modules. In order to guarantee the work between continuity andintegrity.Always said: the system hardware is a foundation, and the system software isalso known as the soul. A good software system can promote the advantages ofsystem automation.To satisfy the actual demand. And to achieve better standard ofsafety broadcasting. To improve the television broadcast quality and workingefficiency more effectively.This paper based on hard disk broadcasting system of the Urumqi TV station.According to systematic framework of Hard disk broadcasting system of Urumqi TVstation, Focus on design of the whole software frame of Hard-disk BroadcastingSystem in Urumqi TV station. First of all, To elaborate the development process oftelevision broadcast system, To Discuss the composition of hard disk broadcastingsystem. To introduce the MPEG video coding technology of Hard disk broadcastingsystem. Networking technology, Brief introduction of RAID storage technology, andthen Combining the actual situation Of Hard-disk Broadcasting System in UrumqiTV station.To analyze the ideas design,function design and Realization forBroadcast module, Material upload module, Broadcasting control module, Themodule technology, The program material management module, Broadcast statisticsmodule of Hard-disk Broadcasting System software in Urumqi TV station. In theend,to Briefly discuss the content and test process method of Broadcasting systemsoftware.This paper focuses on the analysis and design of Hard disk broadcasting systemsoftware. It can provide an actual reference of the hard disk broadcasting system inthe TV station. |
