拟人化音频比对分析技术在发射业务内容监管中的应用

Applicaiton of Anthropomorphic Audio Comparison and Analysis Technology in Transmitting Service Content Supervision

本文介绍了宁波发射台站在业务内容监管方面的应用探索,通过对全链路各路由信号的相关性比对分析,可完成拟人化的音频内容实时监管,有效判断出播出节目的合法性以及音频质量劣化情况。该技术实现了信号的自动故障分析、预警及智能切换代播,可缩短故障停播时间,并降低人为因素导致的劣播、停播。

This paper introduces application exploration of Ningbo transmitting station in service content supervision.Through correlation analysis of all route signals in the whole link,real-time supervision of anthropomorphic audio content can be completed,and the legality of broadcast programmes and the deterioration of audio quality can be effectively identified.The technology enables automatic fault analysis,early warning and intelligent switching of signals,which can shorten downtime and reduce broadcasting deterioration caused by human factors.
