Abstract
본 발명은 사운드 신호 처리 방법 및 장치에 관한 것으로서, 특히 특수 재생 모드로의 벼환 초기에 발생하는 잡음을 개선하기 위한 특수 재생 모드에서의 스위칭 노이즈 개선 방법 및 장치에 관한 것이다.The present invention relates to a method and apparatus for processing a sound signal, and more particularly, to a method and apparatus for improving switching noise in a special reproduction mode for improving noise generated at the beginning of a native bass in a special playback mode.
본 발명은 특수 재생 기능을 갖는 영상/음성 재생 장치의 사운드 억압 방법에 있어서, 일반 재생 모드에서 특수 재생 모드로의 모드 변환 시에 사운드 억압 제어 신호를 발생시키는 사운드 억압 제어 신호 발생 과정; 및 상기 사운드 억압 제어 신호에 따라서 사운드 스위칭 출력뿐만 아니라 사운드 출력 증폭기의 출력도 억압하는 사운드 억압 과정을 포함함을 특징으로 한다.A sound suppressing method for a video / audio reproducing apparatus having a special reproducing function, the method comprising: generating a sound suppressing control signal for generating a sound suppressing control signal when a mode is changed from a normal reproducing mode to a special reproducing mode; And a sound suppression process for suppressing not only the sound switching output but also the output of the sound output amplifier according to the sound suppression control signal.
본 발명에 의하면 사운드의 초기 출력과 최종 출력을 동시에 억압함으로써, 특수 재생 모드 초기에 스위칭노이즈의 영향을 줄일 수 있을 뿐만 아니라 사운드 억압 시의 노이즈도 줄일 수 있는 효과가 있다.According to the present invention, suppressing both the initial output and the final output of the sound simultaneously reduces the influence of the switching noise at the beginning of the special playback mode and also reduces noise during sound suppression.
