摘　　要：为了更好的保证江西省11个地市共计141个发射台站地面数字电视和数字音频广播(CDR)信号的播出效果和发射质量,由省广播电视局投资,在位于南昌市的省广播电视台节目传输中心十九楼中心机房,利用无线传输方式(3G/4G传输结合数字微波链路回传),建设了一个全省地面数字信号集中回传监测平台,极大地提升了省广电局对各地市地面数字电视无线发射台站播出情况的监管力度和监管质量。In order to ensure quality and efficiency of transmission and broadcasting of DTMB and CDR signal in 141 transmitting stations of 11cities in Jiangxi province,Jiangxi Bureau of Broadcasting and Television funded a monitoring platform for centralized backhaul of DTMB signals in central computer room on the 19th floor of Transmission Center of Jiangxi located in Nanchang.The platform is built based on wireless transmission technology(3G/4G transmission combined with digital microwave link backhaul),which has greatly improved supervision intensity and supervision quality of provincial Radio and Television Administration on broadcasting of terrestrial digital TV wireless transmission stations in various cities.
