Title (EN) INFORMATION COMMUNICATION SYSTEM
(FR) SYSTÈME DE COMMUNICATION D'INFORMATIONS
Abstract:
(EN) T An apparatus (10) for transmitting a communication signal, across one or more pre-existing frequency channels or bands that carry a transmission signal, comprises a memory for storing at least one pre-existing frequency channel or band together with information relating to a strength of the transmission signal carried by the at least one pre-existing frequency channel or band. A controller (24) generates a communication signal to be transmitted across at least one of the channels or bands at a strength sufficient to over-broadcast the transmission signal carried. A mixer (26) receives each of the communication signals generated by the controller (24) and combines said communication signals into a combined mixed communication signal (15). A transmitter (16) transmits the combined mixed communication signal (15) across the at least one pre-existing frequency channels or bands either to replace or add the transmission signal carried by the at least one pre-existing frequency channel.
(FR) L'invention concerne un appareil (10) destiné à émettre un signal de communication, à travers un ou plusieurs canaux ou bandes de fréquence préexistants qui véhiculent un signal d'émission, et comportant une mémoire servant à stocker au moins un canal ou une bande de fréquence préexistant(e) ainsi que des informations se rapportant à une intensité du signal d'émission véhiculé par le ou les canaux ou bandes de fréquence préexistants. Un contrôleur (24) génère un signal de communication à émettre à travers au moins un(e) des canaux ou bandes avec un intensité suffisante pour sur-diffuser le signal d'émission véhiculé. Un mélangeur (26) reçoit chacun des signaux de communication générés par le contrôleur (24) et combine lesdits signaux de communication en un signal mélangé combiné (15) de communication. Un émetteur (16) émet le signal mélangé combiné (15) de communication à travers le ou les canaux ou bandes de fréquence préexistants soit pour remplacer, soit pour ajouter au signal d'émission véhiculé par le ou les canaux de fréquence préexistants.
