Abstract

본 발명은 여러가지 빠르기로 오디오신호를 재생하는 디스크플레이어에 관한 것이다. 본 발명은 재생속도 제어정보를 발생하는 수단과, 재생속도 제어정보에 따라 메인클럭의 주파수와 PLL의 주파수를 가변시키는 가변주파수발생부, 및 가변되는 주파수에 따라 오디오신호를 처리하는 DSP로 구성된다.The present invention relates to a disc player for reproducing an audio signal at various speeds. The present invention comprises means for generating playback speed control information, a variable frequency generator for varying the frequency of the main clock and the frequency of the PLL according to the playback speed control information, and a DSP for processing the audio signal according to the variable frequency. .

따라서, 본 발명은 오디오신호의 재생속도를 가변시킬 수 있는 효과를 제공한다.Therefore, the present invention provides the effect of varying the playback speed of the audio signal.
