Abstract

본 발명은 VCR에 있어서, 일시정지시 캡션을 표시하는 일시정지시 캡션 표시장치에 관한 것으로, 입력되는 영상신호로 부터 캡션데이타를 검출하여 처리하는 캡션데이타 처리수단(1), 상기 캡션데이타 처리수단(1)으로부터 출력되는 신호와 입력되는 영상신호를 혼합하고, 캡션 데이타가 혼합된 영상신호와 입력되는 영상 신호를 선택하여 출력하는 스위칭 및 믹스수단(2), 상기 스위칭 및 믹스수단(2)으로 부터 출력되는 영상신호를 처리하여 저장하는 디지탈 영상신호 처리수단(3), 상기 스위칭 및 믹스수단(2)과 디지탈 영상신호 처리수단(3)으로 부터 출력되는 영상신호를 선택하여 출력하는 스위칭 수단(4), 및 입력되는 키신호에 따라 상기 스위칭 및 믹스수단(2)과 스위칭수단(4)과 디지탈 영상신호 처리수단(3)을 제어하는 마이콤(5)으로 구성된다. 따라서, 본 발명은 캡션 VCR에 있어서, 일시정지모드와 같은 특수 재생시 캡션 데이타의 깨짐으로 인해 발생되는 문자 오동작 및 데이타 에러를 방지하여 정화한 캡션을 표시하는 효과가 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pause caption display apparatus for displaying a caption at pause, caption data processing means (1) for detecting and processing caption data from an input video signal, and the caption data processing means. (1) switching and mixing means (2) for mixing and outputting the video signal inputted from the signal output from (1) and selecting and outputting the video signal mixed with the caption data, and the switching and mixing means (2). Digital video signal processing means (3) for processing and storing the video signal output from the switching means, switching means for selecting and outputting the video signal output from the switching and mixing means (2) and the digital video signal processing means (3) 4) and a microcomputer 5 for controlling the switching and mixing means 2, the switching means 4 and the digital video signal processing means 3 according to the input key signal. Therefore, in the caption VCR, the caption VCR has an effect of displaying the caption that has been purified by preventing the character malfunction and data error caused by the broken caption data during the special playback such as the pause mode.
