Abstract: The invention to which this application relates is to the generation of a font or text on a display screen such as, for example, a display screen of a television set. The present invention provides a means whereby a broadcast data receiver can be used to generate font or text on a nulltransparentnull video background so that a video image on the screen is still viewable which moves yet still reduce the visible flicker of the font or text with respect to the video image. By following the present invention, there is provided a means whereby flickering text which conventionally occurs on transparent backgrounds can be eliminated or at least reduced.
