Abstract

L'invention concerne un procédé et un dispositif d'émission/de réception permettant de fournir un service de diffusion à accès conditionnel qui consiste notamment à générer un mot de commande pour brouiller par codage l'accès conditionnel d'un abonné, et modification des données codées en message de commande d'admissibilité et message de gestion d'admissibilité comportant des données par classification de l'abonné à accès conditionnel et non abonné par activation des données. De plus, le procédé comporte la création d'un flux final par multiplexage du message de commande d'admissibilité, et un flux de couche de base pour un premier service de diffusion, la création d'une trame de couche de base et une trame de couche d'amélioration sur la base du flux final et un flux de couche d'amélioration pour un second service de diffusion, la création d'un signal de diffusion par modulation hiérarchique de la trame de couche de base et de la trame de couche d'amélioration, et l'émission du signal de diffusion.
