Abstract

본 발명은 텔레비젼 방송채널 서치시의 노이즈 뮤트회로에 관한 것으로, 복합 영상신호를 신호처리하여 티브이의 수상기로 디스플레이하는 중에 복합 영상신호의 유무를 체크하여 복합 영상신호가 없으면 티브이의 수상기로 디스플레이하지 않으므로, 채널서치시에 시청자의 시각장애를 방지할 수 있도록 한 것이다.The present invention relates to a noise mute circuit in a television broadcasting channel search. When a composite video signal is signal processed and displayed on the TV receiver, the presence or absence of the composite video signal is not displayed on the TV receiver. In order to prevent the visual impairment of viewers during the channel search.
