基于常规监测设备的地面数字电视广播开场测量方法浅析

摘要

目前，我国对地面数字电视广播设备的工作状态评估主要是通过设备的闭路测试来实现，但测试过程依赖专业设备，步骤也较为简化。本文在充分调研数字电视广播技术的基础上，从无线电监测角度出发，设计了地面数字电视广播设备的开场测试实验，充实了现有开场测试内容和步骤，对利用常规监测设备监测地面数字电视广播系统的工作状态的方法进行了探索。%At present,the assessment of ground digital television broadcasting equipment working condition is mainly through closed circuit testing in china,which is mainly depends on specialized equipment,and the procedure is also relatively simple. In this paper,we first make full investigation of digital TV broadcasting technology,then designed a open test methods based on radio monitoring equipments,thus enrich and refine the opening test contents and steps,which has certain practical significance.
