Abstract

본 발명은 영화나 음악회를 감상할 경우 화면이 재생될 때까지의 초기기동시간을 줄일 수 있는 레이저디스크플레이어의 초기기동시간단축방법을 제공하기 위한 것이다. 이를 위해 본 발명은, 모드설정부(60)에 신속재생모드가 설정되어 있는지를 판단하는 제1단계와, 상기 제1단계에서 신속재생모드가 설정되어 있는 경우 스핀들모터구동부(30)가 스핀들모터(20)를 구동시키도록 하는 제2단계 스핀들모터(20)가 로크상태인지를 판단하는 제3단계, 상기 스핀들모터(20)가 로크상태로 된 경우 픽업장치(40)에 의해 바이페이즈코드중 트랙번호정보만을 확인하는 제4단계, 트랙번호가 확인된 경우 픽업이송부(50)에 상기 픽업장치(40)를 프로그램영역의 처음부분으로 이동시키도록 하는 제5단계, 상기 픽업장치(40)로 프로그램영역으로부터 데이터를 독취하여 디스플레이구동부(70)를 매개로 디스플레이(80)로 출력하는 제6단계, 상기 픽업장치(40)로 바이페지즈코드의 나머지 데이터와 서브코드를 독취하여 저장해두고서 통상의 재생동작을 행하는 제7단계로 이루어진 것이다.(제2도)The present invention is to provide a method for shortening the initial startup time of a laser disc player that can reduce the initial startup time until the screen is played when watching a movie or a concert. To this end, the present invention provides a first step of determining whether the quick regeneration mode is set in the mode setting unit 60, and the spindle motor driving unit 30 is the spindle motor when the quick regeneration mode is set in the first step. Second step of driving the 20 The third step of determining whether the spindle motor 20 is in the locked state, and when the spindle motor 20 is in the locked state, the biphasic code is picked up by the pickup device 40. A fourth step of checking only the track number information; a fifth step of moving the pickup device 40 to the beginning of the program area when the track number is confirmed; the pickup device 40 In the sixth step of reading data from the program area and outputting the data to the display 80 via the display driver 70, the pickup device 40 reads and stores the remaining data and sub-codes of the bypass code. Regeneration of It consists of the seventh step of doing things (figure 2).

Description

레이저디스크 플레이어의 초기기동시간 단축방법How to reduce the initial startup time of the laser disc player

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명에 따른 레이저디스크플레이어의 초기기동시간단축방법을 설명하기 위한 블럭도.1 is a block diagram for explaining a method for reducing initial startup time of a laser disc player according to the present invention.

Claims (1)

모드설정부(60)에 신속재생모드가 설정되어 있는지를 판단하는 제1단계와, 상기 제1단계에서 신속재생모드가 설정되어 있는 경우 스핀들모터구동부(30)가 스핀들모터(20)를 구동시키도록 하는 제2단계, 스핀들모터(20)가 로크상태인지를 판단하는 제3단계, 상기 스핀들모터(20)가 로크상태로 된 경우 픽업장치(40)에 의해 바이페이즈코드중 트랙번호정보만을 확인하는 제4단계, 트랙번호가 확인된 경우 픽업이송부(50)에 상기 픽업장치(40)를 프로그램영역의 처음부분으로 이동시키도록 하는 제5단계, 상기 픽업장치(40)로 프로그램영역으로부터 데이터를 독취하여 디스플레이구동부(70)를 매개로 디스플레이(80)로 출력하는 제6단계, 상기 픽업장치(40)로 바이페지즈코드의 나머지 데이터와 서브코드를 독취하여 저장해두고서 통상의 재생동작을 행하는 제7단계로 이루어진 것을 특징으로 하는 레이저디스크플레이어의 초기기동시간단축방법.A first step of determining whether the quick play mode is set in the mode setting unit 60, and the spindle motor driver 30 drives the spindle motor 20 when the quick play mode is set in the first step. Step 2 to determine whether the spindle motor 20 is in the locked state, when the spindle motor 20 is in the locked state, only the track number information of the biphase code is checked by the pickup device 40. The fourth step to move the pickup device 40 to the beginning of the program area if the track number is confirmed; the data from the program area to the pickup device 40; In the sixth step of reading and outputting the display 80 to the display 80 via the display driving unit 70, the pickup device 40 reads and stores the remaining data and sub-codes of the bypass code and performs a normal playback operation. 7th Step Initial start-up time shortening method of the laser disk player according to claim made. ※참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: It is to be disclosed based on the initial application.
