ABSTRACT:
The distribution network (67, 68) comprises as many cables as there are satellite signal sources and terrestrial television signals are added on each of these cables to satellite television signals by utilizing a multiple coupler (66). For each group of users there is a shunting unit (70, 71, 72, 73) which is traversed by the cables of the distribution network and which couples each cable to one of the multiple inputs of a switching unit (85 to 92) having multiple outputs in their proximity. For each output this switching unit selects an input as a function of the value of a control signal applied to the output.
