摘要
我台在一次因地铁施工挖断音频传输光纤导致的停播事故中,遇到了AES/EBU数字信号无法被智能音频切换器正确检测的问题。根据故障情况我台技术人员与厂家工程师一起分析、探讨,并就AES/EBU数字音频信号的检测方法进行了研究和改进。因造成本次播出事故的原因和解决过程具有一定的普遍性,为此我们在文中对问题现象、原因和解决方案进行了介绍,希望能对兄弟单位提供一些参考。
In an accident caused by cutting off the audio transmission fiber during subway construction,our station encountered the problem that the AES/EBU digital signal could not be correctly detected by the intelligent audio switcher.Our technical staff analyzed and discussed the fault situation with the factory engineers,and studied and improved the detection method of AES/EBU digital audio signal.The causes and solutions of this broadcasting accident are universal to some extent.Therefore,we introduce the phenomenon,reasons and solutions of the problem in the paper,hoping to provide some references for the brother units.
