Abstract

본 발명은 송신부로부터 전송된 영상신호의 수신환경 변환에 따라서 안테나의 방향 및 위치를 자동적으로 조절함으로서 언제나 최상의 화면을 얻을 수 있는데, 아날로그 형태로 입력된 영상신호를 디지탈 신호로 변환하여 출력하는 변환부(100)와, 상기 변환부(100)로부터 제공되는 디지탈신호 중 기준신호를 검출하여 출력하는 기준신호 검출부(200)와, 기설정된 표준신호를 기록하고 있으며, 상기 기준신호 검출부(200)로부터 제공되는 기준신호와 상기 표준신호를 비교하여, 전송 중 영상신호의 시간지연값 및 크기 변화값을 계산하여 출력하는 비교부(300)와, 상기 비교부(300)로부터 제공되는 시간지연값 및 크기 변화값에 따라서 안테나의 방향 및 각도를 조절하기 위한 조절신호를 출력하는 조절부(400)와, 상기 조절부(400)로부터 제공되는 조절신호에 응답하여 안테나를 구동하기 위한 안테나 구동수단(500)을 포함한다.The present invention can always obtain the best screen by automatically adjusting the direction and position of the antenna in accordance with the conversion of the receiving environment of the video signal transmitted from the transmitter, a converter for converting the video signal input in analog form into a digital signal to output 100, a reference signal detector 200 for detecting and outputting a reference signal among the digital signals provided from the converter 100, and a predetermined standard signal are recorded and provided from the reference signal detector 200. The comparison unit 300 compares the reference signal with the standard signal, calculates and outputs a time delay value and a magnitude change value of the video signal during transmission, and a time delay value and magnitude change provided from the comparison unit 300. Control unit 400 for outputting a control signal for adjusting the direction and angle of the antenna according to the value, and in response to the control signal provided from the control unit 400 The antenna includes a driving means 500 for driving the antenna.
