江苏广播电视发射传输台中心机房采用GVG7000矩阵进行信号的集中切换,用矩阵遥控面板进行AES/EBU数字音频监听的切换操作,值班人员如果要监听不同的信号,需要不断切换所有12路数字音频,不是很方便。如果有自动循环监听功能,值班人员值班时只需要注意监听各路信号即可,不需要频繁的切换操作,可以更快的发现信号的中断和劣播现象。本文就用VB开发GVG7000通信程序进行数字音频循环监听功能进行了探讨。
Jiangsu Broadcasting and Television Transmission Transmission Center Center room using GVG7000 matrix signal centralized switching, using the matrix remote control panel AES / EBU digital audio monitoring switching operation, duty personnel if you want to monitor different signals, you need to constantly switch all 12 digital audio, not convenient. If there is automatic cycle monitoring function, duty personnel on duty only need to pay attention to monitor the signal can be, do not need frequent switching operation, you can find the signal faster interruption and bad broadcast phenomenon. In this paper, the development of GVG7000 communication program with VB digital audio loop monitoring function were discussed.
