<p>Prior to buying television programmes, it is necessary to set up a communication between the subscriber's television decoder and a management centre. Transmission means such as the modem or cable link for interfacing with the management centre are well known. However, said means may be inoperative or simply unavailable in the configuration concerned. For that reason, the invention concerns a decoder comprising second transmission means such as a cellular telephone, a modulator on the main supply line of the decoder or a data over voice modulator.</p> |
