Abstract
본 발명은 영상 기기의 오에스디(OSD : On Screen Display)에 관한 것으로, 특히 알지비(RGB) 비디오 증폭 장치에 오에스디 기능을 추가하기 위한 오에스디 기능을 갖는 비디오 증폭 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an OSD (On Screen Display) of a video apparatus, and more particularly to a video amplifying apparatus having an OSD function for adding an OSD function to an RGB video amplifying apparatus.
오에스디 신호와 비디오 신호를 입력으로 하여 선택 신호에 따라서 선택된 신호를 출력하는 오에스디/비디오 선택부, 상기 오에스디/비디오 선택부의 선택된 신호를 입력으로 하여 콘트라스트 제어 신호에 따라서 콘트라스트를 조절하는 콘트라스트 조절부, 상기 콘트라스트 조절부의 출력 신호를 입력하여 밝기 조절 신호에 따라서 이득을 조절하는 증폭부를 포함하여 모니터 디스플레이에서 인터페이스없이 오에스디 기능을 실행하는 것을 특징으로 한다.A video / video selection unit for receiving a video signal and a video signal and outputting a selected signal according to the selection signal, a contrast control unit for controlling the contrast according to the contrast control signal with the selected signal of the video / And an amplifying unit for receiving the output signal of the contrast adjusting unit and adjusting the gain according to the brightness adjusting signal, thereby executing an OSD function without an interface in the monitor display.
본 발명에 의하면 종래의 비디오 증폭 장치에 오에스디 신호 믹싱(MIXING) 회로를 추가하여 별도의 외부 응용 회로의 구성없이 오에스디 기능을 실현함으로써, 부품 수를 대폭 줄일 수 있으므로 원가 절감을 실현할 수 있고, 오에스디 출력 레벨을 용이하게 조절할 수 있는 효과가 있다.According to the present invention, by adding an audio signal mixing circuit to a conventional video amplifying device to realize an audio-visual function without a separate external application circuit, the number of parts can be greatly reduced, cost reduction can be realized, The output level can be easily adjusted.
