<p>The method relates to the transmission of information in the form of electrical signals, from a server centre 10 to each of several distant terminals 33, and from each of the latter to the server centre 10 by means of, in particular, telephone lines 31 and/or a specialised network 21. It is characterised in that there is provided information addressed to the terminals 33 and information addressed to at least one category of peripheral appliances 50-51 distinct from the terminals 33, in that at least certain of the latter are connected to at least one individual peripheral appliance 50-51 of at least one category, in that the signals corresponding to the information addressed to the said terminals 33 is sent from the server centre 10 to all the terminals 33 currently operating, and in that signals corresponding to the information addressed to peripheral appliances 50-51 are sent only to terminals 33 associated with such peripheral appliances 50-51 which are themselves currently operating, in accordance with sequences differentiated by coded signals, in that all the signals culminating thereat are read at each terminal 33 connected to at least one peripheral appliance 50-51, in that those of the signals which are addressed to one, respectively each, peripheral appliance 50-51 currently operating are selectively extracted, in that the said signals are directed to the desired appliance 50-51 so that the information from the terminal 33 and that from the peripheral appliance 50-51 can be delivered simultaneously, and in that signals are possibly sent to the server centre 10 either from a terminal 33, or from a peripheral appliance 50-51. <IMAGE></p> |
