ABSTRACT:
A picture display device arranged for displaying, as an interlaced television picture, a mixed picture signal on a picture display tube, this picture signal including a television signal produced in accordance with a television standard and a digitally generated picture and/or text information signal, received from, for example, a teletext decoding circuit. In order to eliminate an annoying "jitter" which occurs in a portion of the displayed picture in which the digitally generated picture and/or text information signal is also displayed, a signal is generated which substantially eliminates the interlace in the said portion of the picture.
