Abstract
본 발명은 광디스크 시스템에서 출력되는 비디오 및 오디오의 템포를 제어할 수 있도록 한 광디스크 시스템에서의 템포 제어 방법에 관한 것으로서, 광디스크로부터 독출 및 증폭되어 인가되는 디지탈 데이터 스트림을 복조를 수행하여 프레임 동기 신호의 검출이나 오류 검출, 오류 정정을 수행하는 DSP(Digital Signal Proecssor)부(60)와 DSP부(60)에서 처리된 디지탈 데이터 스트림이 저장/독출되는 메모리(80)를 구비하는 광디스크 시스템에서 출력되는 비디오 및 오디오의 템포를 제어하는 방법에 있어서, 사용자에 의해 템포 업/다운을 위한 키입력이 있는지를 판단하는 단계와; 템포 업/다운을 위한 키입력이 있으면 입력된 템포 업/다운에 대응하여 DSP부(60)의 처리를 위한 클럭 분주비를 설정하여 광디스크에서 독출된 비트 스트림을 처리하고, 상기 클럭 분주비에 대응하여 광디스크의 회전속도를 변경하는 단계와; 상기 클럭 분주비에 대응하여 상기 DSP부(60)에서 처리된 디지탈 스트림을 저장 및 독출시키기 위한 메모리 클럭을 발생하여 메모리(80)의 저장 및 독출을 수행하는 단계와; 상기 메모리(80)에서 독출된 비트 스트림을 오디오 데이터와 비디오 데이터로 구분하여 각각 출력 및 디스플레이가 가능한 신호로 처리하여 출력하는 단계를 포함한다.The present invention relates to a tempo control method in an optical disc system capable of controlling the tempo of video and audio output from an optical disc system, (Digital Signal Processor) unit 60 for performing detection, error detection and error correction, and a memory 80 for storing / reading digital data streams processed by the DSP unit 60. [ A method of controlling a tempo of audio, comprising: determining whether there is a key input for a tempo up / down by a user; If there is a key input for the tempo up / down, a clock division ratio for processing of the DSP unit 60 is set corresponding to the inputted tempo up / down, and the bit stream read out from the optical disc is processed. Changing the rotational speed of the optical disc; Storing and reading out the memory 80 by generating a memory clock for storing and reading the digital stream processed by the DSP unit 60 corresponding to the clock division ratio; And separating the bit stream read from the memory 80 into audio data and video data, and processing and outputting the processed signals as output and display signals, respectively.
