<p>A signal storage system in which a plurality of selectable graphic terminals (GR1...GR4) are connectable through a multiplexer device (13) to signal utilisation means (17) is characterised in that the multiplexer device (13) includes channel switching means (14) and a channel discrimination signal output circuit (15), and the signal utilisation means (17) include a channel discrimination recognition circuit (20), fed from the signal output circuit (15), a signal take-in element (18) fed from the switching means (14), a signal storage circuit (19) supplied with signals from the element (18), a memory (22) in which regulation and specification values appropriate to said graphic terminals (GR1 to GR4) are stored and a central processing unit (CPU) providing correct regulation by controlling the element (18) in accordance with information stored in the memory (22), whereby the need for regulation in the multiplexer device (13) is avoided, enabling said device to be of simple and inexpensive construction. Figure 1 shows four graphic terminals GR1 to GR4 feeding into a multiplexer (13) which comprises channel switching means (14) and a channel output circuit (15). A hard copy system in the block (17) has a video signal take-in element connected to the switching means (14), a channel recognition circuit connected to the output circuit (15), a picture signal store (19), a RAM (22) and a CPU (21) in control operative association with the element (18), signal storage circuit (19), channel discrimination recognition circuit (20) and memory (22). </p> |
