Abstract

L'invention concerne un procédé et un système de stockage et de lecture de contenus de radiodiffusion, ainsi qu'un dispositif d'émission de droits associé. Le système comprend une unité d'établissement de réservation de téléchargement permettant de créer des informations de calendrier de réservation pour chaque abonné, par le biais d'une interface utilisateur fournissant un service de réservation de téléchargements se rapportant au moins à un élément de contenus de radiodiffusion d'un calendrier de radiodiffusion, et de transmettre les informations de calendrier de réservation à un terminal de radiodiffusion-télévision correspondant. Le système comprend également une unité d'établissement de réservation d'enregistrements audio-vidéo permettant de créer des informations de calendrier de réservation pour chaque abonné, par le biais d'une interface utilisateur fournissant un service de réservation PVR et PAR se rapportant au moins à un élément de contenus de radiodiffusion d'un calendrier de radiodiffusion, et de transmettre les informations de calendrier de réservation à un terminal de radiodiffusion-télévision correspondant. Le système comprend en outre: une unité de gestion de configuration de radiodiffusion permettant de gérer des informations de configuration de radiodiffusion se rapportant au calendrier de radiodiffusion; une unité d'intégration des DRM pour réaliser une intégration des DRM se rapportant aux contenus de radiodiffusion; une unité d'exécution de CAS pour effectuer un traitement CAS se rapportant aux contenus de radiodiffusion afin d'établir des informations CAS correspondant aux contenus de radiodiffusion; et une unité d'émission de radiodiffusion pour exécuter un brouillage se rapportant aux contenus de radiodiffusion tributaires d'une intégration des DRM et des informations CAS, et multiplexer et radiodiffuser les contenus de radiodiffusion et les informations CAS brouillés en même temps que les informations de configuration de radiodiffusion. Un service est mis en œuvre sur une base telle qu'un terminal, adapté pour recevoir des signaux de radiodiffusion transmis selon un calendrier de radiodiffusion, télécharge et stocke des contenus de radiodiffusion correspondants selon un calendrier de réservation préétabli, ou exécute un enregistrement audio-vidéo de contenus de radiodiffusion actuellement regardé, et un droit de lecture est accordé séparément pour les contenus de radiodiffusion de sorte que, à l'expiration dudit droit, ou lorsque les contenus de radiodiffusion sont uniquement copiés et diffusés, ces contenus ne puissent être lus, ce qui incite à l'acquisition du droit de lecture.
