Abstract

La présente invention porte sur un procédé d'estimation d'emplacement et de transmission de données selon lequel les informations d'emplacement des points d'intérêt (POI) sont incorporées sous la forme d'un filigrane numérique dans un signal audio devant être émis par un haut-parleur ou une diffusion de source audio similaire au niveau du point d'intérêt (POI), et les stations d'abonnés (5) estiment l'emplacement des points d'intérêt (POI) par décodage des filigranes numériques au moyen des décodeurs de filigrane numérique audio.
