摘　　要：单频网是地面数字电视广播系统的重要组网模式和应用方式。本文重点介绍了符合GB20600-2006的地面数字电视国家标准单频网系统的基本概念、单频网网络结构以及单频网的建设,并以2007年北京地区技术试验为例简单说明了地面数字电视单频网的调整和优化。In order to meet the request of complicated application of a networked production and broadcasting system, a simulated operating environment should be constructed, before completely and formally implementing the system, to find and settle different problems that might appear during field debugging. And this method is a necessary choice in building networked production and broadcasting system with large and broad business service. Combining with the practice of the new TV center at Beijing TV station, the article introduces and analyses construction requirements, practical cases and application foreground of simulated operating environment of networked production and broadcasting system at TV station. We hope the article will be a reference for other TV stations.
