Abstract

L'invention concerne un procédé de fourniture et de transmission de données de contenu à l'intérieur d'un réseau de communication qui est constitué d'au moins une unité (AE) de travail, notamment un serveur (S), et d'au moins deux unités (ENE) d'utilisateur final différentes. Selon l'invention, les données de contenu sont enregistrées sous la forme de fichiers sur un support (M) de mémorisation associé à l'unité (AE) de travail pour pouvoir, lors d'une interrogation de certaines données de contenu concernant les deux unités (ENE)ou plus d'utilisateur final, transmettre celles-ci aux unités (ENE) d'utilisateur final qui effectuent l'interrogation et les traiter sur celles-ci, notamment pour pouvoir les délivrer sous une forme visuelle et/ou sonore au moyen d'une unité de sortie. Toujours selon l'invention, pour pouvoir effectuer le traitement, notamment pour la diffusion visuelle et/ou sonore, il est nécessaire de procéder à une adaptation de ces données de contenu précises aux unités (ENE) d'utilisateur final qui effectuent l'interrogation respective en fonction du type des unités (ENE) d'utilisateur final ou des ressources techniques présentes sur les unités (ENE) d'utilisateur final.
