Abstract

본 발명은 디지탈 오디오신호의 출력장치에 관한 것으로, 비데오신호의 가변속재생시 동시에 출력되는 오디오데이타의 출력신호의 음질을 향상시키는 디지탈 오디오신호의 출력제어장치에 관한 것이다. 본 발명의 장치는 메모리에 저장된 디지탈 오디오데이타를 외부로부터의 속도제어신호에 따라 선택적으로 출력하므로 가변속 재생시 디지탈 오디오데이타의 음질을 향상시키는 이점을 제공한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for outputting a digital audio signal, and more particularly to an output control apparatus for a digital audio signal for improving the sound quality of an output signal of audio data simultaneously outputted at variable speed reproduction of the video signal. The apparatus of the present invention selectively outputs the digital audio data stored in the memory according to a speed control signal from the outside, thereby providing an advantage of improving the sound quality of the digital audio data at variable speed reproduction.
