摘要
介绍了一项广播电视播出监视技术的原理及其相关电路。对发射播出节目的射频功率和视音频信号进行监测,当发生中断事故时,可及时告警,有效地防止事态扩大。
The technique principle and corresponding circuits in monitoring of broadcasting and television are designed. With the design, the RF power and AV signals of broadcasting programs are monitored. Meanwhile, the alarm is given in time when the interrupt appears, which can effectively avoid the worse situation going on.
