Abstract

본 발명은 TV 화면에 디스플레이되는 폭력장면 또는 애정물 등 어린이 또는 미성년자가 시청해서는 않되는 부분을 OSD를 이용하여 방송신호에 포함된 특정부분의 위치데이타에 의해 자동으로 가리거나 시청자가 키이를 수동으로 조작하여 OSD를 통해 특정부분의 유해화면이 가려지도록 한 특정부분의 유해화면 가림방법에 관한 것으로, 종래 TV는 튜너부(1)에서 선국된 방송신호가 IF처리부(2)에서 중간주파수 처리된 후 음성신호가 출력되고 영상신호는 크로마부(5)를 통해 색차신호로 변화되어 CPT(6)에 디스플레이되므로서 어린이, 미성년자 등이 시청해서는 않되는 폭력장면 또는 애정물등이 디스플레이될때 TV전원을 차단하거나 TV채절을 바꾸어 주어야 하는 문제점이 있었다.According to the present invention, a part which is not watched by a child or a minor, such as a violent scene or an affection displayed on a TV screen, is automatically covered by position data of a specific part included in a broadcast signal using an OSD or a viewer manually hides the key. The present invention relates to a method of screening harmful screens of a specific part by operating the OSD so that the screen is screened through a OSD. In the conventional TV, a broadcast signal tuned by the tuner unit 1 is processed by an IF processor 2 after an intermediate frequency is processed. When the audio signal is output and the video signal is converted into the color difference signal through the chroma unit 5 and displayed on the CPT 6, the TV power is cut off when a violent scene or affection is displayed which children, minors, etc. should not watch. There was a problem to change the TV sig

본 발명은 이와같은 종래 문제점을 해결하기 위하여 어린이 또는 미성년자가 시청해서는 않되는 폭력 장면 또는 애정물 등의 유해화면이 디스플레이될 때 방송신호에 포함된 유해 영상 가림의 위치테이타를 디코딩한 후 OSD를 이용해 유해화면이 자동으로 가려지도록 하고, 시청자의 키이조작에 의해 수동으로 특정부분의 유해화면이 가려지도록하여 폭장면 또는 애정물등의 유해화면을 어린이 또는 미성년자등이 시청하지 못하도록 영상기기에 적용한다.In order to solve such a conventional problem, the present invention decodes the position data of the occlusion of the harmful video included in the broadcast signal when a harmful scene such as a violent scene or an affection that is not watched by children or minors is displayed. The harmful screen is automatically covered and the harmful screen of a certain part is manually covered by the viewer's key operation so that the harmful screen such as a wide surface or an affection is not applied to the video device.

Claims (1)

사용자가 TV를 시청중 특정부분 화면이 가려지게 설정된 모드가 자동모드인 지 판단하는 제1과정과, 판단결과 자동모드이면 데이터 슬라이서부(13)를 통해 방송신호에 포함된 특정부분 영상의 수평, 수직위치 데이터를 티코딩하여 이를 수평/수직위치 디코더부(153)(154)에 각각 설정하는 제2과정과, 디코딩된 수평/수직위치 데이터가 수평/수직위치 디코더부(153)(154)에 설정되었으면 전제 OSD를 제어하는 OSD제어부(155)의 제어신호에 따라 특정부분 영상 화면이 가려지게 해당 영상에 OSD를 실시하는 제3과정과, 상기 제1과정의 결과 수동모드이면 키이매트릭스부(14)의 수평/수직위치 키이신호에 따라 특정부분 영상의 수평/수직위치 데이터를 수평/수직위치 디코더부(153)(154)에 설정한 후 OSD제어부(155)의 제어신호에 의해 해당 영상이 가려지게 OSD를 실시하는 제4과정으로 진행되는 특정부분의 화면 가림방법.The first process of determining whether the mode set to cover the screen of a specific part of the user while watching TV is the automatic mode, and if the automatic mode determines that the screen of the specific part is included in the broadcast signal, the horizontal, A second process of recording the vertical position data and setting them in the horizontal / vertical position decoders 153 and 154, and the decoded horizontal / vertical position data in the horizontal / vertical position decoders 153 and 154. If it is set, the third process of performing the OSD on the corresponding image so that the specific part of the video screen is covered by the control signal of the OSD control unit 155 controlling the entire OSD, and the key matrix unit 14 if the manual mode is the result of the first process. After setting the horizontal / vertical position data of a specific part of the image to the horizontal / vertical position decoders 153 and 154 according to the horizontal / vertical position key signal, the corresponding image is blocked by the control signal of the OSD controller 155. Foreclosure OSD 4 screen blanking process of a particular part of how to proceed. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
