摘　　要：地市级广播电视节目至各县无线发射站点的信号传输大都采用广电网络DVB-C的单一方式。本文以玉溪市为例,分析了利用各发射站点间的开路信号作为独立于广电网络系统之外低成本信源备份的可行性。DVB-C of the radio and television network is the single mode to primarily apply to transmit local broadcast signals from the prefecture-level radio and television programs to wireless base stations in counties. Taking Yuxi as an example, this research analyses the feasibility of employing the opencircuit signal between the transmission stations as a low-cost source backup, which is independent of the radio and television network system.
