摘　　要：实现地面的数字电视基站建设,实际上是整个电视发展领域中,包括地面的无线电数字电视、卫星电视、有线电视等多方面最早的一种端口到端口之间的数字化革命开展。这种创新在一定程度上体现为其是建立在信道调制以及信源压缩之前的关键性技术特点,所以这项工作的开展实际上也在一定程度上促进了电视广播技术的全面发展与技术突破,同时也切实促进了广播电视实现数字化革新与发展。为此本文从发射基站的选择角度出发,探究了其选择过程中常见的一些问题。分析出现阶段电视发射机房常见的供电问题、雷电预防问题、常见故障等,希望能够切实提出自身在无线地面数字电视基站建设方面的一些体会与思考,同时也切实提高了无线地面数字电视基站的整体建设水平。The construction of terrestrial digital TV base station is actually the earliest port to port digital revolution in the whole field of TV development;including terrestrial radio digital TV,satellite lycable TV and so on.To a certain extent;this innovation is reflected in its key technical characteristics established before channel modulation and source compression.Therefdre;the implementation of this work has not only promoted the all-round development and technical breakthrough of TV broadcasting technology to a certain extent,but also effectively promoted the digital innovation and development of radio and television.Therefbre;this paper explores some common problems in the selection process from the perspective of the selection of transmitting base stations.lt analyzes the common power supply problemsjightning prevention problems,common faults and so on in the TV transmitting room,hoping to put forward some experiences and thoughts on the construction of wireless terrestrial digital TV base station,and effectively improve the overall construction level of wireless terrestrial digital TV base station.
