Abstract

본 발명은 텔레비젼의 온 타임시 영상신호 제어장치에 관한 것으로, 온타임 시간이 되어 온타임 동작시 적외선 감지센서(21)에서 사람의 유무를 감지하여 사람이 없을 경우에는 음성처리부(14)를 통하여 음성만 출력되게 구성하고, 사람이 있을 경우에는 음성처리부(14)와 영상 처리부(15)를 통하여 영상과 음성이 정상적으로 출력되게 구성한 것이다.The present invention relates to an apparatus for controlling video signals during on-time of a television. When the on-time operation is performed, the infrared sensor 21 detects the presence or absence of a person and the voice processing unit 14 detects the presence of a person. Only audio is output, and if there is a person, the audio and video are processed through the audio processor 14 and the video processor 15.
