Abstract

L'invention porte sur un récepteur et un afficheur de données radiodiffusées pouvant extraire sélectivement des divers types de données radiodiffusées des informations requises par l'utilisateur du dispositif. Divers types de fichiers de données et un fichier de gestion contenant les informations attributs sont radiodiffusés. L'utilisateur sélectionne un titre désiré dans la liste des tables d'informations préparées à partir du fichier de gestion et récupère uniquement le fichier de données du titre sélectionné. Selon une autre variante, l'utilisateur désigne à l'avance la catégorie, etc., des informations désirées, la compare avec les informations attributs de chaque fichier de données et récupère uniquement le fichier de données correspondant. Les informations attributs peuvent contenir les informations de positionnement relatives aux fichiers de données radiodiffusées. Lorsque le récepteur et l'afficheur des données radiodiffusées est utilisé avec un dispositif de navigation de véhicule, la position indiquée par les informations de positionnement relatives à un fichier reçu et l'emplacement actuel de l'utilisateur sont indiqués sur une carte, et le contenu du fichier sélectionné est affiché automatiquement ou conformément à une instruction de l'utilisateur de la carte.
