Abstract (en)
[origin: EP0053661A2] At output units (AE) which are suitable for the "videotex" of the communications service, graphics patterns can be represented in a coarse pattern by graphics elements (GE) and alphanumeric characters can be represented in a fine pattern by means of picture elements (BP). Furthermore, it is possible to represent graphics patterns in accordance with the characters in the fine pattern. The patterns represented by the picture elements (BP) are stored in a random-access memory (Z3). They are input by first representing the graphics patterns in a coarse pattern by means of the graphic elements (GE) and subsequently allocating a picture element (BP) to each graphics element (GE). The picture elements (BP) are combined to form character fields (ZF) and are stored. They are called up by code words (CW3) and represented at the output unit (AE). <IMAGE>
