Abstract

L'interface applicative (API) de l'invention permet à des applications (applets, par exemple), dans un récepteur de télévision numérique, de récupérer des informations du système (SI) à partir d'un train de transport numérique, indépendamment du format SI spécifique. L'API soustrait les parties pertinentes des SI et les présente dans un format générique exploitable. Ce système peut s'utiliser, p. ex., avec des format SI, notamment le "MPEG Program Specific Information (PSI)", le "DVB SI", l'"ATSC Program and System Information Protocol (PSIP)", le "Cable SI" ( comme le "Digital Video Standard 234"), et les SI privées. Dans une forme de réalisation optionnelle, une transmission asynchrone des SI est fournie pour les SI qui ne sont pas immédiatement disponibles dans la mémoire du récepteur. En outre, l'API peut aussi soustraire les SI de sorte qu'elles soient indépendantes du format spécifique du train de transport (p. ex. MPEG-2). Par ailleurs, on effectue l'extraction incrémentale de données SI en permettant à une application de s'adjoindre un petit sous-ensemble de SI disponible dans le récepteur, de l'analyser, et, au besoin, d'extraire des SI supplémentaires sur la base de cette analyse. L'API inclut un progiciel de navigation (110), un progiciel guide de programme (120), un progiciel de sélection et de réglage de programme (130), un progiciel de description (140), un progiciel utilitaire (150), un progiciel de données (160) et un progiciel pipeline (170).
