Abstract

본 발명은 디스크의 재생도중 전원을 차단하거나 정지버튼을 눌러서 재생동작을 종료한 다음에 전원을 공급하고 계속버튼을 누르면 다시 그 종료위치부터 재생가능하도록 된 레이저디스크플레이어의 계속재생방법을 제공하기 위한 것이다. 이를 위해 본 발명은, 모드설정부(20)에 재생계속모드가 설정되어 있는지의 여부를 판단하는 제1단계와, 마이컴(100)이 가장 최근에 정지모드 또는 전원차단 모드로 된 때의 정지화상메모리(25)에 저장된 저장화면을 출력하도록 하고 그후 초기화동작을 수행한 다음에 상기 정지화상메모리(25)에 저장되어 있는 상기 저장화면에 대한 위치정보를 입력받는 제2단계, 스핀들모터구동부(55)가 스핀들모터를 구동시키도록 하고 상기 위치정보에 따라 픽업이송부(60)가 픽업을 이송시키도록 하는 제3단계, 위상동기루프가 안정상태로 되었는지의 여부를 판단하여 위상동기루프가 안정상태로 되었다고 판단되면 상기 위치정보에 따른 디스크상의 위치에서 재생동작을 개시하도록 하는 제4단계, 상기 모드설정부(20)에 정지모드 또는 전원차단모드가 설정되어 있으면 그 시각에서 정지화상메모리(25)에 비디오 신호처리부(30)로부터 입력된 비디오신호를 저장하도록 함과 더불어 마이컴(100)으로부터의 그 종료위치에 대한 위치정보를 입력받아 저장하도록 하는 제5단계를 구비하여 이루어진 것이다.The present invention is to provide a method for continuously playing a laser disc player which can be played back from the end position when the power is supplied and then the continue button is pressed after the power is cut off or the stop button is pressed. will be. To this end, the present invention provides a first step of determining whether or not the continuous playback mode is set in the mode setting unit 20, and a still image when the microcomputer 100 is most recently in the stop mode or the power-off mode. Outputting a stored screen stored in the memory 25 and performing an initialization operation thereafter, and receiving a position information on the stored screen stored in the still image memory 25; a spindle motor driver 55 Step 3) to drive the spindle motor and the pick-up transfer unit 60 to transfer the pick-up according to the positional information, and determine whether the phase-locked loop is in a stable state. In the fourth step of starting the playback operation at the position on the disc according to the positional information, the stop mode or the power-off mode is set in the mode setting unit 20. A fifth step of storing the video signal input from the video signal processor 30 in the still picture memory 25 at that time, and receiving and storing the position information of the end position from the microcomputer 100; It is made.

Claims

A first step of judging whether or not the playback continue mode is set in the mode setting section 20, and stored in the still picture memory 25 when the microcomputer 100 has recently entered the stop mode or the power down mode; The second step of receiving the position information on the storage screen stored in the still picture memory 25 after performing the initialization operation to output the storage screen, the spindle motor drive unit 55 drives the spindle motor The third step of causing the pickup transfer unit 60 to transfer the pickup according to the position information, and determining whether the phase synchronization loop is in a stable state and determining that the phase synchronization loop is in the stable state. In the fourth step of starting the playback operation at the position on the disc according to the information, if the stop mode or the power-off mode is set in the mode setting unit 20, And a fifth step of storing the video signal input from the video signal processor 30 in the memory 25 and receiving and storing the position information of the end position from the microcomputer 100. A continuous play method of a laser disc player.

※ Note: It is to be disclosed based on the initial application.
