一、组网方式卫星电视地球接收站的组网方式大致可分为以下三类:第一类是利用卫星电视地球接收站接收卫星传送的电视节目,供家庭收看或录制;第二类是将接收到的电视节目在中频上用功率分配器分配给不同的集体接收用户,第三类是将接收到的电视节目通过发射机或CATV转发出去,供用户收看。为了便于区别,有时将前两种方式称为单收站(TVRO),后一种方式称为收转站。 First, the way of networking Satellite television earth receiving station networking can be broadly divided into the following three categories: The first category is the use of satellite television earth receiving stations to receive satellite television programs for family viewing or recording; the second category is to The received television programs are distributed to different group receiving users by the power splitter at the intermediate frequency. The third type is to transmit the received television programs through the transmitter or CATV for users to watch. For the sake of distinction, the first two methods are sometimes referred to as TVRs, the latter as a transfer station.
