CD플레이어 시스템에서의 인덱스 검출방법Index Detection Method in CD Player System

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

컴팩트 디스크의 트랙의 코드에 대한 타임을 신호처리기(DSP)에서의 검출완료됨을 마이크로컴퓨터(MIC)에서 판단하고, 마이크로컴퓨터(MIC)는 현재의 트랙과 검출트랙을 같을 때까지 비교하여 픽업을 구동하여 전진 또는 후진시키며, 현재의 인덱스와 검출인덱스와 비교하여 같아질 때까지 픽업을 전진 또는 후진시키는데, 현재의 인덱스가 검출 인덱스 보다 클 때에는 픽업을 후진시키고 현재의 인덱스가 검출인덱스 보다 작을 때에는 픽업을 전진시키며, 현재의 인덱스가 검출 인덱스와 같을 때에는 픽업을 정상 플레이속도로 구동시킨 다음 오디오 신호를 일정 시간동안 뮤팅시키고 인덱스 검출완료를 나타내고, 검출인덱스를 찾는 도중에 픽업을 전진 또는 후진시킴에 따라 서로 다른 트랙일 경우에는 인덱스모드 해제를 표시하고 찾고자 하는 트랙의 처음부분으로의 검출동작을 실행시키며, 트랙검출시에는 픽업구동을 플레이속도보다 100배 정도의 속도로 구동하고, 인덱스 검출시에는 플레이속도 보다 10배정도 빠른 속도로 픽업을 구동시키게 하여 인덱스를 검출하는 것을 특징으로 하는 CD 플레이어 시스템에서의 인덱스 검출방법.The microcomputer MIC determines that the time for the code of the track of the compact disc is detected by the signal processor DSP, and the microcomputer MIC drives the pickup by comparing the current track with the detection track until the same. Forward or backward by moving forward or backward until the current index is equal to the detection index. The pickup is reversed when the current index is greater than the detection index, and the pickup is made when the current index is smaller than the detection index. When the current index is equal to the detection index, the pickup is driven at the normal play speed, and then the audio signal is muted for a predetermined time, indicating the completion of the index detection, and when the pickup is moved forward or backward while searching for the detection index, the difference is different. In the case of a track, mark the index mode cancel and When the track is detected, the pickup is driven at a speed of about 100 times the play speed, and when the index is detected, the pickup is driven at a speed about 10 times faster than the play speed. An index detection method in a CD player system, characterized in that. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
