国标地面数字电视单频网的组网与建设

Combination and Construction of Chinese Standard's Ground Digital Television Single Frequency Net

在研究国内相关标准、技术的基础上,主要对地面数字电视单频网组网中涉及的关键技术单频网组网的同频干扰与建站距离等问题进行分析和阐述,并开发了采用两种机制的网络管理系统软件,解决了单频网组网过程中相关设备远程管理的问题。同时,介绍了山西省国标地面数字电视单频网的建设情况。

On the basis of studying domestic related standards and technique, this text mainly analyzes and illustrates the key technique in the process of net combination-that is the co-channel frequency interference and the distance of constructing positions of single frequency net. For developing the net management system software that uses two kinds of mechanism, it solves the problems on remote management of related equipments in the process of combing the single frequency net. At the same time, this text introduces the con- structing situation of Shanxi Province＇s ground digital television single frequency net.
