Abstract

L'invention concerne des procédés et des systèmes destinés à améliorer l'utilisation d'un décodeur par un utilisateur. Elle se rapporte également à un système permettant à un utilisateur de s'abonner à un service de télévision payante lorsqu'il choisit de visualiser le contenu de ce service de télévision payante. L'invention concerne en outre un système de reproduction d'informations de configuration pour décodeurs ainsi qu'un système destiné à surveiller et bloquer un contenu en cours de visualisation par un autre utilisateur. L'invention porte enfin sur un système permettant la représentation d'un contenu de programmation non télévisuelle sous la forme d'une chaîne d'un guide de programmes électronique.
