Abstract

본 발명은 캡션기능을 내장한 티브이 시스템에 있어서, 캡션신호의 합성출력장치에 관한 것으로, 종래에는 티브이에 있어 방송국에서 송신되어지는 캡션신호를 단지 화면에만 디스플레이시키는 기능에 국한되어져 있어서 캡션신호의 기록성은 불가능하였다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite output device for caption signals in a TV system incorporating a caption function, and is conventionally limited to a function of displaying a caption signal transmitted from a broadcasting station only on a screen. Was not possible.

따라서 종래의 문제점을 기록성을 가능하도록 하기 위하여 본 발명은 캡션의 자막신호를 티브이의 영상신호와 합성 또는 선택적으로 영상출력단에 출력하여 일반영상과 함께 녹화재생기(VCR)에 녹화가능하도록 하였다.Accordingly, in order to enable the recordability of the conventional problem, the present invention synthesizes the caption signal of the caption with the video signal of the TV or selectively outputs it to the video output terminal to enable recording on the recorder (VCR) together with the general video.
