1 概述播出监测系统是保障广播电视安全播出的重要部分,随着数字电视的发展,特别是数字压缩卫星技术的应用,需要监测的播出节目套数越来越多,同时为了便于判断故障,还需增加不同传输接点的监测信号,这样需要监测的信号可达几十路。通常对电视信号的监视做法是用几十个9寸监视器组成庞大、笨重的监视器阵列,由值班员进行监看。然而面对同时显示几十路信号的监视器墙进行监看十分困难,工作效率很低,经常出现失误。
1 Overview Broadcast monitoring system is an important part of security broadcasting security, with the development of digital television, especially the application of digital compression satellite technology, broadcast programs need to monitor more and more sets, and in order to facilitate the determination of failure , But also need to increase the monitoring signal transmission contact, so you need to monitor the signal up to dozens of ways. The usual monitoring of television signals is the use of dozens of 9-inch monitors to form a large, cumbersome monitor array that is monitored by attendants. However, in the face of dozens of signals at the same time in the face of the monitor wall to monitor very difficult, low efficiency, often mistakes.
