Abstract
본 발명을 텔레비젼 문자 방송 수신시의 방송 신호 무신호시에 사운드를 자동으로 뮤트시키고 전원을 오프시킬 수 있는 문자 방송 처리 시스템의 사운드 뮤트 회로에 관한 것으로, 이를 위하여, 종래의 문자 방송 처리 시스템에 운자 방송 선택시의 방송신호 무신호시에 문자를 디코딩하는 디코더의 뮤트포트에 입력되는 뮤트 신호에 의거하여 영상 신호 처리부에서 시스템의 전반적인 제어를 위해 출력되는 ID 신호를 바이패스시키기 위한 트랜지스터를 부가하여 구성하고, 방송 신호 무신호시에 문자 디코더에 인가되는 뮤트 신호를 이용하여 사운드를 직접 뮤트시켜 주므로서, 종래장치에 비해 사용상의 편리성을 증진시키고 불필요한 전원 낭비를 방지한것이다.The present invention relates to a sound muting circuit of a text broadcasting processing system capable of automatically muting the sound and turning off the power when no signal is broadcast at the time of receiving a television text broadcasting. And a transistor for bypassing the ID signal output for overall control of the system by the video signal processor based on the mute signal input to the mute port of the decoder which decodes the character when no broadcast signal is selected. By muting the sound directly by using the mute signal applied to the character decoder when no signal is broadcast, it improves the convenience of use and prevents unnecessary waste of power compared to the conventional apparatus.
