Abstract

L'invention porte sur un langage de définition d'applications (ADL) de TV interactive (ITV) servant à générer de telles applications destinées à différents types de plates-formes et dispositifs. L'ADL offre plusieurs types de structures de données fondamentales sur lesquelles on peut construire une ou des structures de données. Les structures de données contenant des informations de présentation et de comportement de contenus ITV sont dénommées "ressources". Une ressource est associée à un identificateur globalement unique permettant de stocker et d'extraire efficacement une structure de données d'une table de hachage. Une ressource est également associée à un horodatage d'expiration indiquant quand la ressource doit être libérée par la mémoire. Une ressource présente une longueur arbitraire et contient des valeurs différant de celles stockées dans un dispositif récepteur client. Les ressources sont également stockées dans un module d'assistance à la plate-forme et/ou au profil d'un client récepteur lequel peut rapidement déterminer si le module le concerne, en examinant l'identité de la plate-forme et/ou du profile contenu dans l'en-tête du module.
