1. A reconfigurable in-house multiplepoint wired network for the simultaneous and/or alternative distribution of several types of data including, notably, audio-visual signals comprising, amongst others, baseband image signals, among sets of devices, each comprising at least one unit for the injection of signals into the network and at least one unit for the reception of said signals, each said unit capable of being connected, without distinction, at different connection points of the network,a network of the type formed by at least one line for the transmission of said signals provided with connection points of said units to the network, distributed over the length of said line,wherein each transmission line is formed by a twisted pair of conductors comprising at least one input point for the connection of a unit for the injection of a signal into said pair of conductors;

  • and several output points for the connection of units for tapping said signal transmitted on the pair of conductors,where each of said at least one input point comprises means for the symmetrical injection of the signal on the two wires of said pair of conductors, said means for the injection having a high impedance with respect to the impedance of said pair,and wherein each of said output points comprises means for the symmetrical tapping of the signal on the two wires of said pair,said means for the tapping having a high impedance with respect to the impedance of said pair of conductors, compatible with a multiple tapping of the signal on the pair of conductors.
