随着IT技术和广播电视技术的不断发展,IT技术在广播电视领域的应用日益广泛,根据查看播出情况的需要,我台原来5个频道的监播监录系统是有线电视信号通过5个机顶盒分别调出长春电视台5个频道的电视节目分别送给5台监播录像机上录成录像带,每天还要定时换录像带,既浪费人力物力,查看录像带时录像效果并不是很好。因此采用了一套简单实用的电视播出信号监播监录报警系统,对播出的电视信号进行监控报警,提示值班员进行及时处理故障。监播监录报警系统是在工控机上安装视音频采集卡,通过软件控制视音频处理芯片来实现实时监控的监播监录系统。
With the continuous development of IT technology and radio and television technology, the application of IT technology in the field of radio and television is becoming more and more widespread. According to the need of viewing broadcast conditions, the original monitoring and monitoring system of five channels in our TV station passed the five signals Set-top boxes were transferred out of Changchun TV 5 channels of television programs were sent to 5 monitors recorded on video tape recorders, but also regularly change tapes, not only a waste of human and material resources, when viewing video tapes when the effect is not very good. Therefore, a set of simple and practical television broadcast signal monitoring broadcast monitoring alarm system, the broadcast television signal monitoring alarm, prompt on duty to promptly deal with failure. Monitor broadcast monitoring alarm system is installed in industrial computer video and audio capture card, video and audio processing chip through software control to achieve real-time monitoring of broadcast monitoring system.
