<p>The information processing circuit includes a source of data - for example a keyboard and processor, connected by an interface to a further processor managing operation of the installation. This processor communicates with an image memory receiving information to provide a video display signal. A video signal generator comprises an address scanning circuit controlling the sequential reading of memory zones containing the information to display a symbol. Vertical and horizontal speed scanning circuits control the rate of scanning of the address locations, and a synchronous mixer provides the resulting video signal.</p> |
