<p>Matrix switch for sharing out to M outputs, by choice, a signal selected from N signals conveyed to as many inputs on the matrix, each of the M outputs being switchable at will onto one of the N inputs as a function of a remote-control signal, characterised in that it comprises a support structure (2) for a set of input cards (1) each receiving the video signals (V), corresponding in number to a given sub-multiple of the total number of signals N to be transmitted; at least one set of switching cards (3), each of which is connected to one input card (1); and at least one sub-set of output cards (5), all of them connected to the set of switching cards (3) and each delivering an arbitrary signal selected from the signals received by each switching card, the switching cards comprising a set of input cells (E) mounted in parallel, equal in number to the sub-multiple defining the number of video signals to be transmitted, and a set of output cells (S), each input cell and each output cell being connected by a switching cell (C), allowing a selected signal to pass from the input to the output under the effect of a control instruction. …<IMAGE>… </p> |
