KR970031923A - Subtitle Generator for TV Receiver - Google Patents

Abstract

The present invention relates to a subtitle generating device for a television receiver which visually displays an operation state of the television receiver and its operation state to a viewer, and includes image processing means for processing a broadcast signal and outputting RGB and luminance signals accordingly; Subtitle generation means for outputting an RGB and blanking signal for generating a subtitle screen according to an operation signal input, and outputs a mixture of RGB signals from the image processing means and the subtitle generation means, when the blanking signal is inputted. A television receiver comprising a mixer means for outputting an RGB signal from the means, the television receiver comprising: first storage means for controlling the caption generating means and storing control data for generating a caption screen in a first size mode; Control the caption generating means to display the caption screen of the second size mode larger than the first size mode. Second storage means for storing control data for making a selection, selection means for selectively setting the first size mode and the second size mode by a viewer, and mode storage means for storing the size mode selected by the selection means. And control means for controlling the caption generating means based on the control data stored in the second storage means in accordance with the size mode stored in the mode storage means.
