ABSTRACT:
A communication installation for communal reception of digital television and/or of multimedia data, which receives a plurality of signals emanating from separate sources. The installation of the invention comprises a network linking a multiplicity of descrambler/decoder devices, available to the users of the community, to a local server capable of demodulating the signals received so as to despatch them over the network in the form of a stream of packets of common modulation, with software applications allowing the descrambling/decoding of the signals. Thus, off-the-shelf descrambler/decoder devices of similar designs can process the various signals received.
