大型数字广播搬迁工程系统暗伤分析和解决实例

System analyses and internal injury solutions during large audio broadcasting system relocation

在新广播技术大楼智能化播出系统建设及旧播出系统搬迁过程中,多次出现音频卡顿,幅度高低起伏等暗伤现象,通过从广播发射、音频传输、总控、播出音频工作站以及录音各个环节逐一排查,并组织技术骨干联合会诊、试验分析,从全局层面解决了多个系统性难题。

This paper describes a step by step solution to system problems in the large audio broadcasting project construction. Though one by one detection in every link of audio broadcasting,audio transmission,audio routing,audio broadcasting workstation and audio recording,By an expert team,these have been solved such as an audio loss of short time and ups and downs in audio amplitude. Mathods have been used including joint consultation,experimental analysis and system approach. Integrated with the above measures,good results are obtained.
