Abstract

Abstract Means are provided for storing videotex-type graphics information in a server center (10) connected to a telephone network (14), with said graphics information relating to at least one image, and for modifying the stored graphics information in response to instructions transmitted from terminals (18) connected to the telephone network and provided with screens (18a) on which at least a portion of said image can be displayed. The graphics information stored in the server center is converted into television-type video signals so as to enable an image to be displayed on one or more television receiver screens (34) or television image projectors, with the displayed image corresponding, at least in part, to the image represented by the graphics information stored at any instant in the server center. As a result, each change made to the graphics information from a terminal such as a "Minitel" appears immediately in the image displayed by the screen of a television receiver.
