Abstract

본 발명은 세컴 칼라(SECAM COLOR) 방식의 OSD에 있어서 OSD문자 부위에 세컴 칼라의 영향으로 문자가 끌리는 현상을 방지하기에 적당한 VCR의 OSD 글자 끌림 방지회로에 관한 것으로 비디오 신호를 받아들이는 비디오신호 입력부(1), 비디오신호 입력부(1)의 출력을 완충시키기 위한 제1버퍼(4), 제1버퍼(4)를 통한 복합 비디오신호중에서 칼라신호만 선택하는 칼라신호 선택부(5), 제1버퍼(4)와 연결되고 화면상에 OSD문자를 표시하기 위한 OSD IC(2), 제1버퍼(4)의 출력측에 접속되어 콘트롤 신호에 의하여 스위칭되는트랜지스터(Q1), 칼라신호 선택부(5)의 칼라신호와 OSD IC(2)의 비디오 신호를 믹서하여 출력시키는 비디오신호를 출력부(3), 비디오 신호 출력부(3)의 출력을 완충시키는 제2버퍼(6)를 구비하여 OSD 문자 끌림을 제거하도록 한 것이다.The present invention relates to an OSD character drag prevention circuit of a VCR suitable for preventing a character dragging due to the influence of the Secom color in an OSD character part in an OSD of a SECAM COLOR type video signal input unit for receiving a video signal. (1), a color signal selector (5) for selecting only a color signal from among a composite video signal through the first buffer (4) and the first buffer (4) for buffering the output of the video signal input unit (1) Transistor Q1 and color signal selector 5, which are connected to the buffer 4 and connected to the output of the OSD IC 2 for displaying OSD characters on the screen, and to the output side of the first buffer 4, and switched by a control signal. OSD signal having a video signal for mixing and outputting the video signal of the OSD IC (2) and a second buffer (6) buffering the output of the video signal output unit (3). It is to remove the attraction.
