Abstract

본 발명은 영상기기에 있어서 원하는 화면은 원하는 위치에 원하는 크기로 설정하여 한 화면상에 두 화면을 디스플레하는 화면 편집 장치(Picture In Picture 이하 PIP라 칭함)에 관한 것으로, 특히 텔레비젼의 PIP기능 선택시 부 화면이 특정한 위치에 있을 경우에만 주/부 화면을 동시에 모니터링하도록 제어함으로써, 시청자의 필요에 따라 주/부 동시 화면 또는 주 화면이나 부 화면을 시청하면서 주 화면만을 녹화할 수 있도록 구성된 것이다.The present invention relates to a screen editing device for displaying two screens on a screen by setting a desired screen at a desired position at a desired position in a video apparatus. By controlling the main / sub picture to be monitored at the same time only when the sub picture is in a specific position, the main screen can be recorded while watching the main / sub simultaneous screen or the main screen or sub picture according to the needs of the viewer.
