摘要
从目前数字技术的发展趋势来看,地面数字电视终将替换彩电,成为接收电视节目的主流机体。地面数字电视发射机取代模拟电视发射机自然也将成为必然。地面数字电视广阔的市场需求也给地面数字电视发射机的检修和维护工作带来了更大的难度。要保证地面数字电视的日常运转,就必须对店面数字电视发射机的运维提出新要求。本文将借助地面数字电视发射机的运行原理,具体分析地面数字电视发射机的运维措施。
From the current development trend of digital technology,terrestrial digital TV will eventually replace color TV and become the mainstream body of receiving TV programs.The replacement of analog TV transmitter by terrestrial digital TV transmitter will naturally become inevitable.The broad market demand of terrestrial digital TV also brings more difficulty to the maintenance and maintenance of terrestrial digital TV transmitter.In order to ensure the daily operation of terrestrial digital television,it is necessary to put forward new requirements for the operation and maintenance of store digital TV transmitter.This paper will analyze the operation and maintenance measures of terrestrial digital TV transmitter with the help of the operation principle of terrestrial digital TV transmitter.
