Abstract
The sound-signal broadcaster utilizing the IEEE 802.11 standard including the transmission of a periodic IEEE 802.11 beacon frame signal separate from the transmitted data and representative of the period number of the beacon frame signal, includes: elements for receiving signals according to standard IEEE 802.11 representing: the beacon frame signal, and at least one packet representative of the sound signals to be broadcast into which a period number of the beacon frame signal has been incorporated, so as to broadcast the sound signal represented by each data packet at a predefined time on the basis of the period number incorporated into the packet. The broadcaster may include elements for determining a processing operation to be executed on each received packet on the basis of the difference between the period number of the received beacon frame signal and the period number of the beacon frame signal incorporated into the received packet.
