摘要
有线电视网络灾备系统对于广电行业很有实用意义,但是目前并没有成熟而完善的标准和要求,本论文是在国家广播电影电视总局科研项目《有线电视网络灾备系统需求及技术体系研究》的基础上总结而成,通过研究有线电视网络灾备系统需求,提出针对有线电视网络系统应建立一套包括前端系统、网络传输系统、业务运营支撑系统、重要内容及数据等方面的整体灾备技术体系。
Cable TV network disaster recovery system is of practical signifi cance for the radio and television industry, but there is no mature and perfect standard and requirement. Based on the research project of 'The cable TV network disaster recovery system requirements and technological system ' in SAPPFRT,the author has written the essay. Through the study of the Cable TV network disaster recovery system demand, the system should include front-end system,network transmission system,business operation support system,important content of data recovery and so on.
