Abstract: A device for displaying a number of lines of characters which are separated from each other by spacing lines on a television tube, comprising a circulating store for one line of characters which is connected to the output of a buffer store for the information of the entire image. An output of the circulating store is fed back to an input of the buffer store. The insertion and deletion of characters is effected by shifting the information between buffer store and circulating store over one or more character positions. Under the control of the correspondence signals from x, y cursor device, the input of the buffer store is then switched over from its own output to the output of the circulating store, with the result that the information in the buffer store is shifted. A vacant position thus produced is available for a new character.
