Abstract
본 발명은 안테나에 입력되는 전계강도의 변화에 따라 가변되는 AGC전압을 이용하여 안테나를 자동으로 조절할 수 있도록 한 안테나 자동조정 시스템에 관한 것으로, TV/VCR에서의 영상신호의 레벨변동을 억제하기 위해 영상신호에서 검출되어 튜너 제공되고 외부안테나에 입력되는 전계강도에 상응하여 가변되는 AGC전압을 이용하여 외부 안테나에 근접 부착된 모터를 회전구동 시킴으로써 안테나가 시계 또는 반시계 방향으로 회전되도록 구성하여, 사용자의 이용상의 편리성을 개성한 것이다.The present invention relates to an antenna automatic adjustment system for automatically adjusting the antenna using AGC voltage which is variable according to the change in electric field strength inputted to the antenna, in order to suppress the level variation of the video signal in the TV / VCR. The antenna is rotated clockwise or counterclockwise by rotating the motor close to the external antenna using the AGC voltage detected by the image signal and provided to the tuner and varying according to the electric field strength input to the external antenna. The convenience of use is individualized.
