Abstract

본 발명은 전원 온(ON)/오프(OFF)시에 발생하는 팝노이즈를 제거하여 깨끗한 화면과 음성을 시청취할 수 있는 팝노이즈 제거장치에 관한 것이다. 본 발명은 전원 온(ON)/오프(OFF)시 시스템 각 구성의 동작이 안정되기 이전에 오디오처리부와 비디오처리부에서 발생되는 각종 노이즈의 출력을 뮤트시켜 팝노이즈 제거하도록 구성된다. 따라서, 본 발명은 전원 온/오프시에 발생되는 팝노이즈를 제거하여 깨끗한 화면 및 음향신호를 생성할 수 있는 효과를 제공한다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pop noise removing apparatus capable of removing a pop noise generated when a power is turned on / off and a clean screen and audio can be viewed. The present invention is configured to remove pop noise by muting outputs of various kinds of noise generated in the audio processing unit and the video processing unit before the operation of the system configuration is stabilized when the power is turned ON / OFF. Accordingly, the present invention provides an effect of generating a clean screen and a sound signal by eliminating pop noise generated when the power is turned on / off.
