Abstract
본 발명은 주문형 비디오(VOD : VIDEO ON DEMAND)의 시스템 정보 이용을 위한 가입자 댁내 장치(STB: SET TOP BOX)에 오디오 디지털/아날로그 변환기에 뮤트회로를 연결 노이즈를 제거하는 방법에 관한 것으로, 중앙처리 장치와 사용자 인터페이스의 뮤트단자의 신호를 OR게이트로 조합한 뮤트제어신호를 뮤트회로에 인가하여 노이즈를 제거하는 방법과 전원 인가후 상태가 변한 중앙 처리 장치의 뮤트단자를 이용하여 음량을 조절하는 것을 특징으로 사용자에게 듣기에 거부감이 없는 향상된 음향을 제공할 수 있어 매우 유용하다.The present invention relates to a method for removing noise by connecting a mute circuit to an audio-to-digital-to-analog converter to a set-top box (STB) for using system information of video on demand (VOD). A method of removing noise by applying a mute control signal combining a signal of a mute terminal of a device and a user interface with an OR gate to a mute circuit, and adjusting the volume using a mute terminal of a central processing unit whose state is changed after power is applied. This feature is very useful because it can provide the user with an improved sound with no rejection.
