摘　　要：电视台新闻制播网的建设中,安全是最重要的一环。本文通过一个全新的视角、全新的概念——A、B岛分岛式架构来实现新闻制播系统的安全,通过将演播室之前的系统模块分成相对独立的两个分系统,通过系统级别的互备,极大提高了新闻网的安全。In construction of TV news production and broadcasting network, safety is the most important factor. Through new perspective and new concept, an architecture of AB islands is adopted to realize the safety of news production and broadcasting system. Through the module of the system, before the studio, divided into relatively independent subsystem and through mutual standby system level, the news network＇s security has been improved greatly.
