Synchronised multi-topical information broadcasting permitting a reconfigurable listening strategy over a transmitter park and of radio programmes

摘要

The field of the invention is that of the broadcasting of information messages by a park of radio transmitters with distributed transmission frequencies, destined for fixed or mobile receivers. The objective is to allow a single receiver to be listening, in an optimised way, to several transmitters broadcasting regularly updated information messages. This objective is achieved with the aid of a method characterised in that each transmitter (21, 22, 23) continuously broadcasts a cycle made up of a variable number of messages, each cycle of messages being partitioned into successive blocks of fixed duration, identical for all the transmitters, in that each block comprises an initial informatory marker, termed the state marker, and each cycle comprises an initial informatory marker (24, 25, 26), termed the synchronising marker, and in that the starts of cycle (24, 25, 26) of each transmitter (21, 22, 23) of the park are shifted from one transmitter to the next.
