Abstract

L'invention concerne un support d'enregistrement destiné à une trame de service d'informations de point d'intérêt/nouvelles ainsi qu'un appareil destiné à traiter un service d'application basé sur TPEG au moyen de celui-ci. L'appareil comprend un récepteur destiné à recevoir un flux de diffusion basé sur le protocole TPEG associé aux informations de trafic et de voyage (TTI) par l'intermédiaire d'un réseau de communication de diffusion, un analyseur destiné à analyser la trame de diffusion reçue, à supprimer les trames présentant des erreurs et à extraire les trames dépourvues d'erreurs, un décodeur destiné à classifier les trames extraites par données associées aux TTI par analyse de caractéristiques de composants de service des trames extraites, une unité de stockage permettant de stocker et de gérer les données associées aux TTI classifiées dans une base de données associées aux TTI correspondante, un contrôleur destiné à recevoir une demande de service TTI en provenance d'un utilisateur, à effectuer une recherche dans une base de données associées aux TTI correspondante conformément à la demande de service TTI et à produire en sortie les données associées aux TTI recherchées, ainsi qu'une unité de sortie destinée à produire en sortie les données associées aux TTI correspondantes.
