Title (EN) METHOD FOR UPDATING LOCAL MAP DISPLAYING DATABASES
(FR) PROCEDE DE TRANSFERT DE L'INFORMATION
Abstract:
(EN) A method of updating local map displaying databases of a distributed database via a broadcasting system with a transfer capacity. In a first step it is determined what information the distributed database needs to be updated with. In a second step the information is arranged according to a priority scheme. In a third step the information is transferred to the local map displaying databases via the broadcasting system according to the priority scheme and in dependence of the transfer capacity of the broadcasting system.
(FR) La présente invention concerne un procédé de mise à jour de bases de données pour affichage de cartes locales à partir d'une base de données répartie par l'intermédiaire d'un système de radiodiffusion doté d'une capacité de transfert. Dans un premier temps, on détermine les informations requises pour la mise à jour de la base de données répartie. Dans un deuxième temps, l'information est agencée selon un système de priorités. Enfin, l'information est transférée dans les bases de données pour affichage de cartes locales via un réseau de radiodiffusion selon le système de priorité et selon la capacité de transfert du réseau de radiodiffusion.
