Abstract

The present invention relates to a television receiver for teletext for receiving a composite video signal having text informa-tion multiplex on a television video signal, and more particularly to a television receiver for teletext capable of displaying the television video signal and teletext screen simultaneously on the picture screen by superimposing or dividing the screen, and according to this television receiver for teletext, which comprises preprocessing means for issuing various preprocessing correction signals on the basis of the teletext signal extracted by the teletext signal receiving means, the preprocessing correction signal issued by the preprocessing means, and the teletext signal received by the teletext signal receiving means are combined and displayed on the picture screen, and thereby the boundary of the television video signal and teletext signal is clearer, so that the text of thetelet ext signal is easier to read.
