Abstract

본 발명은 위성방송 수신기에 사용하는 안테나의 방송신호를 수신상태를 표시하는 것으로서 종래에는 전압계 및 테스터등의 계기를 사용하여 AGC전압의 레벨을 측정하였으므로 계기가 없는 일반 사용자들은 위성방송의 수신화면을 시청하면서 안테나의 설치방향을 조절하여 최적의 상태로 안테나를 설치하기가 매우 어려웠으며, 이로 인하여 안테나의 설치률 전문적인 안테나 설치업자에 위탁하여 사용자에게 많은 경제적인 부담을 주었다.The present invention indicates the reception state of a broadcast signal of an antenna used in a satellite broadcast receiver. In the related art, general users without a meter can receive a reception screen of a satellite broadcast because the AGC voltage level is measured using a voltmeter and a tester. It was very difficult to install the antenna in the optimal state by adjusting the installation direction of the antenna while watching, and this entrusted a lot of economic burden to the user by entrusting the antenna installation rate to a professional antenna installer.

본 발명은 AGC전압레벨을 계기로 측정하지 않고, 그 AGC전압레벨을 판별하여 표시장치 및 0SD화면으로 방송신호의 수신상태를 표시함으로써 사용자가 표시된 방송신호의 수신상태를 보고 간단히 안테나의 설치방향을 조절할 수 있다.According to the present invention, the AGC voltage level is not measured by an instrument, and the AGC voltage level is determined and the reception state of the broadcast signal is displayed on the display device and the 0SD screen. I can regulate it.
