Research And Application Of Integration Technology In Broadcasting And Television System

With the close contact of IT and TV broadcasting technology, all stages of the TV program producer can be achieved by IT system. But, because at the beginning of construction every TV station just considered the single service function realized by networked system and ignored the comprehensive integration solution, it is caused that information isolated island is ubiquitous and resources can't be shared, so the advantages of network can't be realized. It has great significance for business development to resolve the question of interconnection in TV stations. In the radio and television industry facing digital and network trend, this thesis aims to discuss the network technology application and the system integration architecture in the distributed and heterogeneous system.This thesis first studies the level and some kinds of technical architecture, discussing the principle, level and key components about the process from interaction to integration. Also it lists four major mistaken ideas in system integration and the future technology development about interconnection are expected. On this basis, it presents the design of system integration architecture. As the practice to the theory, the author puts forward overall planning and design about the construction of the whole-station network based on the principle above.Secondly, this thesis gives a profound analysis of the key technology with regard to interoperability solutions. Enterprise Service Bus (ESB) and Enterprise Media Bus (EMB) are integration models orienting heterogeneous application system based on SOA architecture and interconnection models realizing interactive process among plenty of audio-video files used in the radio and television industry. Some TV station selected this technology to achieve the interconnection.Finally, taking the construction of some whole-station network as an example, the thesis expounds how to design and carry out the system integration from three levels about hardware platform, data application system and business process. And this thesis introduces the data flow analysis and the design of the key business process in detail. The application of dual bus technology in process design is introduced taking video information filing as case in the thesis. The result of this thesis has entered actual application in some TV station. It brings good effects including improving program production efficiency and reducing production cost for this TV station.
