Abstract

L'invention concerne un procédé de contrôle d'accès, en télévision numérique payante, à des informations contenues dans un signal reçu par une station de réception abonné (21) comprenant des étapes d'émission de premiers messages de contrôle d'allocation de droits (ECM) permettant de proposer aux abonnés un mode de fonctionnement à la demande et de seconds messages de gestion d'allocation de droits (EMM) vers un dispositif utilisateur (26), de génération dans le dispositif utilisateur (26) d'un signal d'autorisation d'accès (CW), dans lequel on émet des premiers messages de contrôle d'allocation de droits ayant un contenu de profil paramétrable permettant d'autoriser au moins un service ou un programme pendant une certaine fenêtre de temps en fonction du profil d'un abonné déterminé, de maniere à réaliser une certaine interactivité entre le contenu de ces premiers messages et le contenu du dispositif utilisateur en termes d'abonnement pour l'abonné.
