Abstract

공동 안테나를 통해 위상방송을 수신하여 분배한 후 공동 수신 시스템 라인을 통하여 소수의 가입자에게 송신하는데 유리한 위성방송 공동 수신회로가 개시되는바, 이는 상기 중앙 안테나를 통해 수신된 위성방송에서 공청지역의 각 가입자가 전송한 채널 선국 데이타와 각 가입자의 고유 클럭에 따라 각각 소정 채널을 선국하여 UHF 밴드에서 각각 FM 변조한 후 결합하여 출력하는 송신회로와, 상기 송신회로에서 결합되어 출력되는 UHF-FM 변조된 소정개의 채널 주파수중 각 가입자의 채널 선국 데이타와 고유 클럭에 따라 해당 채널의 주파수를 선국한 후 위성 중간 주파수로 변환하여 위성 수신기로 출력하는 가입자 회로가 소정개 구비되는 수신회로로 구성되어, 공동 안테나를 이용하여 수평 편파와 수직 편파의 위성신호를 선택 수신한 후 가입자의 선국 데이타와 고유 클럭에 의해 소정 채널을 선국하고 UHF-FM로 변조하여 공동 수신 시스템 라인을 통해 전송하고, 공청 지역의 각 가입자의 수신기에서는 각 가입자가 선국한 채널의 UHF-FM 신호를 위성 중간 주파수로 변환함으로써, 채널 유료화 및 스테레오가 가능하고, 또한 위성 채널 수만큼 복조기와 변조기가 필요 없으므로 비용이 절감되면서 소규모 시스템에 적합하다.A satellite broadcasting joint reception circuit is disclosed, which is advantageous for receiving and distributing a phase broadcast through a common antenna and transmitting it to a small number of subscribers through a joint reception system line. A transmission circuit for tuning a predetermined channel according to the channel tuning data transmitted by the subscriber and a unique clock of each subscriber and performing FM modulation on the UHF band, respectively, and combining and outputting the UHF-FM modulated signal coupled and output from the transmission circuit. It consists of a receiving circuit having a predetermined subscriber circuit for tuning the frequency of the corresponding channel according to the channel tuning data and the unique clock of each subscriber among the predetermined channel frequencies, and converting the frequency of the corresponding channel into a satellite intermediate frequency and outputting it to the satellite receiver. Select and receive satellite signals of horizontal and vertical polarization using The channel is tuned by the station data and the unique clock, and modulated by UHF-FM and transmitted through the common reception system line.The receiver of each subscriber in the public area transmits the UHF-FM signal of the channel tuned by each subscriber to the satellite intermediate frequency. By converting to, it is possible to pay for channels and stereo, and it is suitable for small-scale systems while reducing the cost since there is no need for demodulators and modulators as many as satellite channels.
