Apparatus and method for displaying caption broadcast and teletext on the screen of a double-wide television

摘要

An apparatus and method for displaying a caption broadcast and teletext on a wide screen of a double-wide television are provided in which a televised picture and a caption broadcast or teletext are separately displayed without any overlap. The apparatus includes first and second comb filters for converting first and second broadcast signals into luminance (Y) and chrominance (C) signals. The apparatus also includes a signal separating circuit for separating a second video signal output from the first comb filter into a first picture signal and caption and teletext signals, a switching circuit for selectively outputting a first video signal output from the first comb filter and the caption and teletext signals output from the signal separating circuit, a double-picture processing circuit for processing the first picture signal output from the signal separation circuit and the caption and teletext signals output from the switching circuit so that pictures corresponding to the first picture signal and the caption and teletext signals can be displayed in left and right portions of the wide screen, respectively.
