Abstract

이 발명은 자화면(Picture In Picture : PIP) 디스플레이 기능을 갖는 영상기기에 있어서, 자화면내 자화면 전용의 온스크린 디스플레이(On Screen Display: OSD) 문자를 디스플레이시킬 수 있도록 한 텔레비젼 자화면내 온 스크린 디스플레이 구현회로에 관한 것이다.The present invention relates to a video apparatus having a picture in picture (PIP) display function, wherein an on-screen display (OSD) character of a screen dedicated to a child screen can be displayed. Screen display implementation circuitry.

이 발명은 자화면 회로내부에 자화면용 OSD를 위한 캐릭터 롬을 내장하여 마이콤으로부터의 제어에 의해 자화면용 OSD문자를 발생시켜 자화면 영상신호에 자막을 삽입하여 자화면 내부에 자화면용 OSD를 디스플레이시킬 수 있게 됨으로써 사용자는 모화면과 자화면의 수신채널 및 비데오 선택등을 쉽게 알 수 있게 된다.The present invention embeds a character ROM for an on-screen OSD in a sub-screen circuit to generate an on-screen OSD character under control from a microcomputer, inserts a subtitle into the sub-screen video signal, and inserts a subtitle into the sub-screen. Being able to display the user can easily know the receiving channel and video selection of the parent screen and the child screen.
