Abstract
The information is transmitted on a carrier signal within a plurality of successive time frames each partitioned by a predetermined number of time intervals, each of which is allotted to a predetermined group of receivers. The receivers of each group are furthermore distributed into a predetermined number of identifiable sub-groups of receivers. All the receivers of the group are activated at the start of the corresponding allotted time interval, all the receivers of the group are made to receive service information identifying which are the sub-groups in which the receivers are likely to receive a message, this service information is analysed within each receiver and, before the end of the time interval (I.sub.3), a receiver not belonging to one of the designated sub-groups is de-activated.
