Abstract

본 발명은 임의의 채널 및 브이씨알을 시청중 사용자가 원하는 타채널의 방송상태를 캡션을 통해 자막으로 동시에 시청할 수 있도록한 캡션표시 장치에 관한 것으로, 현재 디스플레이 되는 화상의 영상이 CCD로 디스플레이 되므로서 청각장애자가 아닌 일반인에게는 CCD시스템의 사용의미가 없으며, 임의의 채널 및 브이씨알을 시청중, 사용자가 원하는 타채널의 방송상태를 확인할 수 없는 문제점을 해결하기 위한 것이다.The present invention relates to a caption display device which enables a user to simultaneously watch a broadcasting channel of another channel desired by a user while capturing an arbitrary channel and V-Cal through captions. The general public who does not have a hearing impairment has no meaning of using a CCD system, and is intended to solve a problem of not being able to check a broadcasting state of another channel that a user wants while watching an arbitrary channel and VRC.

본 발명은 이와같은 종래 문제점을 해결하기 위하여 CCD기능이 내장된 TV용 마이컴을 구비하므로서 임의의 채널방송 및 브이씨알을 시청중 사용자가 원하는 타채널의 방송상태 즉 뉴스등을 자막을 통해 동시에 시청할 수 있게 하므로서 청각 장채자 및 일반인들도 CCD를 이용가능하게 한 것으로, CCD시스템에 적용한다.The present invention is provided with a microcomputer for TV with a built-in CCD function in order to solve such a conventional problem, while watching the arbitrary channel broadcasting and V-CAL, the user can simultaneously watch the broadcasting status of other channels, that is news, etc. through subtitles. By making the CCD available to the auditory collectors and the general public, it applies to CCD systems.

Claims

A video selection switch (SW31) for selecting one video signal to be currently viewed from a plurality of video signal sources, a caption video selection switch (SW32) for selecting one video signal for caption data extraction from a plurality of video signal sources; The caption data extraction unit has a caption data extraction unit 37 for extracting caption data from the image signal selected by the caption image selection switch SW32, and an interface unit 49 for receiving its own OSD function and external caption data. A multi-channel caption display device comprising a microcomputer 34 for outputting caption data extracted at 37 to the screen selected by the image selection switch SW31 as an OSD subtitle, and a memory unit 38 storing the channel switching data. .

A first process of determining key input, a second process of setting a multi-channel CCD mode to on / off toggle if the key input determination result is a multi-channel CCD key input, and a CCD channel switching key input as a result of the key input determination result In the case where the CCD mode is turned on by the first process, a third process of sequentially switching the CCD channel input is performed, and as a result of the key input determination, it is determined whether or not the TV control OSD is currently in the multi-channel CCD mode turned on. And the fourth step of terminating after executing the OSD related to the TV, and resetting the attributes of the CCD channel which has been switched in the third process or in the current TV control OSD as a result of the determination of the fourth process, and caption caption of the reset attribute. A multi-channel caption display method comprising a fifth step of displaying the OSD to the screen currently being watched.
