Abstract

본 발명은 외부 충격에 의한 시스템의 불안정한 상태를 신속하게 보상함으로 뮤트(Mute)를 제거하도록 한 광디스크 플레이어에 관한 것으로서, 광디스크 플레이어의 디지털 신호 처리부에서 신호 처리된 테이터를 일정한 지연 시간을 두고 각각 저장한 후 디지털 아날로그 변환기로 출력하는 제1, 제2버퍼부가 포함되도록 구성하여, 광디스크의 초기 구동시 버퍼에 저장하여야 할 테이터량이 적으므로 초기 구동 시간이 단축되고, 외부 충격이 연속적으로 가해지더라도 제1버퍼부 및 제2버퍼부가 선택적으로 출력되도록 하여 광디스크의 데이터를 정확하게 재생시킬 수 있음과 아울러 외부로 출력되는 오디오 신호는 뮤트되지 않는 효과가 있다.The present invention relates to an optical disc player capable of eliminating a mute by quickly compensating for an unstable state of a system caused by an external impact, and more particularly, to an optical disc player in which a signal processed by a digital signal processor of an optical disc player is stored Analog converter, the initial driving time is shortened because the amount of data to be stored in the buffer is small at the initial drive of the optical disc, and even if the external impact is continuously applied, The first and second buffer units are selectively output to reproduce the data of the optical disc accurately, and the audio signal output to the outside is not muted.
