Abstract

이 고안은 위성방송 수신기의 입력단 제어회로에 관한 것이다.This invention relates to an input stage control circuit of a satellite broadcasting receiver.

이 입력단 제어회로는 종래의 두개의 신호가 입력되는 경우 스위칭 박스나 수동조작에 의해 하나의 신호를 선택하는 불편함을 개선한 것으로 다수의 트랜지스터로 이루어진 스위칭 동작에 의해 다수의 저잡음 블럭(LNB)단자와 각각 연계하여 동작되는 입력단자를 제어전압에 의해 번갈아 동작하도록 구성함으로써, 두 신호의 간섭으로 인한 오동작도 방지될 수 가 있다.This input stage control circuit improves the inconvenience of selecting a single signal by a switching box or manual operation when two conventional signals are input. The plurality of low-noise block (LNB) terminals are provided by a switching operation composed of a plurality of transistors. By configuring the input terminals operated in association with each other by the control voltage alternately, malfunction due to interference of the two signals can be prevented.

따라서 두개의 신를룰 하나의 위성방송 수신기로 수신이 가능하므로 기존에 사용하고 있응 위성방송 수신기에 적용할 경우 생상비 절감등의 탁월한 효과가 있다.Therefore, it is possible to receive with one satellite broadcasting receiver to control two scenes, so when applied to the existing satellite broadcasting receiver, there is an excellent effect of reducing the cost of living.
