Claim 1
Independent Claim
142 words
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) 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.
Claim 2
Dependent Claim
142 words
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) 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.
Claim 3
Dependent Claim
41 words
A system as claimed in claim 1 further characterised in that the graphic terminals (GR1 to GR4) have component colour video signals (RGB); the memory (22) is a random access memory (RAM); and the switching means (14) is comprised of relays.
Claim 4
Dependent Claim
157 words
A hard copy system in which hard copies are obtained from a plurality of graphic terminals having RGB video signals, characterised in that said system comprises a) a multiplexer device (13) which is provided with video signal inputs over a plurality of channels (12) and includes a channel discrimination signal output circuit (15) b) a channel recognition circuit (20) which identifies a channel in accordance with said channel discrimination signal, c) a memory (22) in which regulation values employed in the taking-in of video signals are secured for the plurality of channels, d) a controlling means (21) which reads the regulation value of a selected channel out of said memory means (22) and controls a video signal take-in element (18), and (e) a picture storing circuit (19) which stores as a picture video signals converted into digital signals under the control of said controlling means (21), picture printing being effected by the signals in said circuit (19).
