广播电视大型直播类节目音频制作系统的安全问题及解决方法

On the Security of Audio Production System for Broadcasting and Television Large Live Programs

针对音频制作系统的信号传输,声源拾取、分配,前级处理合成、后级选择输送等环节存在的安全问题给出解决办法,并设计出两种不同节目类型的基本的、安全性相对较高、可以快速应对和解决突发状况的音频制作系统方案,提出"治未病"概念,从设备的使用、管理层面防患于未然。

Aiming at the security problems existing in signal transmission, sound source pickup and distribution, preprocessing synthesis and post-selection transmission of audio production system, this paper presents solutions,and designs two basic audio production system schemes of two different types of programs, which have relatively high security and can quickly respond to and solve sudden situations. The concept of "preventive treatment" is put forward from the use of equipment. At the management level, we should take precautions.
