ABSTRACT:
For supplying a power supply voltage to a Low Noise block with a plurality of different receiver-decoders connected to the same Low Noise block by a cable which transmits an intermediate-frequency signal as well as a power supply voltage intended for the Low Noise block, the receiver-decoders are connected in cascade and the upstream receiver-decoder (5) includes a transfer module (23) which transmits the intermediate-frequency signal of a connector (8) for connection to the Low Noise block to a connector (9) for connection to a downstream receiver-decoder when the upstream receiver-decoder is inoperative, and supplies a power supply voltage between the same connectors in the other direction.
