Abstract
본 발명은 비디오 카세트 레코더(VIDEO CASSETTE RECORDER 이하, 브이씨알이라한다)의 캡션(Caption:자막)장치에 관한 것으로서, 더욱 상세하게는 컨트롤 신호(CTL:Control)의 듀티를 상이하게 하여 기록된 캡션 신호를 재생하여 화면에 표시하는 브이씨알의 자막 표시장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a caption (caption) device of a video cassette recorder (hereinafter referred to as V-CAL). A subtitle display device of a V-Cal to play a video on a screen.
이를 위하여 본 발명은, 컨트롤 신호의 듀티를 상이하게 하여 소정 비트로 코드화 하여 기록된 캡션 신호를 재생하여 표시하는 장치으로서, 재생 동작을 수행하기 위한 키신호를 출력하는 키입력부(1)와; 상기 키입력부(1)에서 인가되는 재생 동작을 수행하기 위한 키신호에 대응하여, 상기 기록된 캡션 신호를 재생하기 위한 제어신호를 출력하고, 재생된 상기 캡션 신호를 디코딩하여 출력하며, 이를 표시하기 위한 표시 제어 신호를 출력하는 마이콤(2)과; 상기 마이콤(2)의 제어에 따라 컨트롤 트랙에 기록된 상기 캡션 신호를 재생하여 상기 마이콤(2)으로 출력하는 컨트롤 헤드(3)와; 상기 마이콤(2)의 제어에 따라 비디오 헤드에 의하여 독출되는 비디오 신호를 처리하는 비디오 신호 처리부(4)와; 상기 마이콤(2)에서 출력되는 표시 제어 신호에 따라 상기 디코딩된 캡션 신호와 상기 비디오 신호 처리부(4)에서 출력되는 비디오 신호를 혼합하여 화면에 표시하는 OSD부(5)를 포함하므로써, 별도의 캡션 회로를 내장하지 않고도 소프트 웨어적으로 처리할 수 있는 효과가 있다.To this end, the present invention provides a device for reproducing and displaying a caption signal recorded by encoding a predetermined bit with a different duty of a control signal, comprising: a key input unit (1) for outputting a key signal for performing a reproducing operation; In response to a key signal for performing a reproducing operation applied by the key input unit 1, output a control signal for reproducing the recorded caption signal, decode and output the reproduced caption signal, and display the same. A microcomputer 2 for outputting a display control signal for the microcomputer 2; A control head (3) for reproducing and outputting the caption signal recorded on a control track to the micom (2) under the control of the micom (2); A video signal processor (4) for processing a video signal read out by the video head according to the control of the microcomputer (2); A separate caption is included by including an OSD unit 5 for mixing the decoded caption signal and the video signal output from the video signal processing unit 4 and displaying them on the screen according to the display control signal output from the microcomputer 2. There is an effect that the software can be processed without the built-in circuit.
