Abstract

위성 수신기의 블루 백그라운드 모드를 수행하기 위한 것으로서, 수신신호중 스크램블된 비데오 신호를 선택적으로 디코더로 출력하는 멀티플렉서에 접지단을 형성시켜서 블루백그라운드 모드시 멀티플렉서의 출력을 접지단의 무신호로 함으로써 안정된 블루 백그라운드 신호를 제공할 수 있는 효과가 있다. 이것은 위성 수신기의 블루 백그라운드 기능을 제공하기 위하여 이용 가능하다.This is to perform the blue background mode of the satellite receiver, and the ground terminal is formed in the multiplexer which selectively outputs the scrambled video signal among the received signals to the decoder, and the blue background signal is stabilized by making the output of the multiplexer no signal of the ground terminal in the blue background mode. There is an effect that can provide. This is available to provide the blue background function of the satellite receiver.
