Abstract

본 발명은 비디오디스크의 재생위치 제어장치와 그 방법에 관한 것으로, 비디오디스크(10)에 대한 등간격의 정지화상 표시모드의 지정과 등간격의 분할구간의 지정을 위한 제어신호입력부(12)와, 그 제어신호입력부(12)에서 입력되는 분할구간 지정을 기초로 그 지정된 위치의 동화상이 정지화상으로 재생되도록 하는 제어부(14), 그 제어부(14)의 제어하에 상기 등간격의 분할구간을 지정하는 시간데이터에 대응하는 위치의 동화상을 정지화상으로 재생해서 CRT장치(30)상에 표시되도록 하는 오디오/비디오디코더(26)를 구비하여, 상기 비디오디스크(10)에 대한 분할구간의 지정을 위한 제어신호에 기초하여 그 비디오디스크(10)의 전체적인 재생시간의 판단 및 그 전체적인 재생시간을 상기 지정된 분할구간으로 균등분할하고, 그 균등분할된 위치에서 정지화면을 재생하여 순차적으로 재생되도록 하는 것이다.The present invention relates to an apparatus for controlling playback position of a video disc and a method thereof, comprising: a control signal input unit 12 for designating a still picture display mode at equal intervals and a division period at equal intervals for the video disc 10; A control section 14 for reproducing the moving picture at the designated position as a still picture based on the division section designation input from the control signal input section 12, and designating the section sections at the same intervals under the control of the control section 14; An audio / video decoder 26 for reproducing a moving picture at a position corresponding to the time data to be displayed on the CRT apparatus 30 so as to be displayed on the CRT device 30, for specifying a division section for the video disc 10. On the basis of the control signal, the determination of the overall reproduction time of the video disc 10 and the entire reproduction time are equally divided into the specified division section, and the image is stopped at the equally divided position. This is to play the faces sequentially.
