Abstract

Méthode et appareil bloquant la réception de programmation télévisuelle qui répond à des critères déterminés. Des paquets de données décrivant la programmation télévisuelle sont diffusés avec le signal de télévision. Les paquets de données comprennent au moins des paquets qui contiennent de l'information de catégorie indiquant un niveau dans une ou plusieurs catégories à plusieurs niveaux et/ou de l'information d'étiquette indiquant l'étiquette appliquée au contenu des émissions du signal. Les paquets de données dans un signal vidéo d'arrivée sont détectés par un appareil de blocage et comparés aux préférences mises en mémoire dans la mémoire non volatile de l'appareil de blocage. Le signal vidéo est bloqué si le contenu des paquets de données correspond aux préférences mises en mémoire ou les dépasse. L'appareil est configurable sur place. L'information de configuration indiquant les règles de codage est diffusée sur un canal séparé. Les méthodes de l'invention sont extrêmement flexibles et permettent d'utiliser simultanément plusieurs systèmes de codage différents.
