数字电视是电视信号数字化后的产物，分为有线传输数字电视、卫星传输数字电视、地面无线传输数字电视。地面无线传输数字电视作为电视广播的传统手段，具有简单接收和移动接收的能力，能够满足现代信息化社会“信息到人”的基本需求。数字电视地面广播的传输和使用能克服恶劣环境的影响，从根本上解决了频谱资源紧张的问题，所以数字电视地面广播的推广和产业化将带来不可估量的经济增长。作为地面数字电视广播系统重要组网方式之一的单频网必将随着地面数字电视的发展而迎来高速发展的时期，而国标（ DTMB标准）地面数字电视单频网也必将随着DTMB标准的推广及国际化而被更多的国家和地区所采纳，其推广前景广阔。主要阐述地面数字电视广播单频网的组网方式、关键技术与指标、测试方法。
