Abstract

Procédé permettant la réalisation d'un contrôle parental, un canal pour établir une correspondance de canaux dans un récepteur de télévision sur protocole Internet (IPTV) et un récepteur TV IP. Le procédé comprend la réception d'un tableau d'information de service (SI) principal composé d'un premier élément définissant l'emplacement d'un tableau de correspondance de canaux virtuels, l'analyse du premier élément dans le tableau d'information de service principal reçu, la réception du tableau de correspondance de canaux virtuels, y compris un deuxième élément définissant l'emplacement d'un tableau de description de canaux virtuels fondé sur l'élément d'emplacement analysé, l'analyse du deuxième élément dans le tableau de correspondance de canaux virtuels reçu, la réception du tableau de description de canaux virtuels, qui comprend un troisième élément indiquant une valeur de surveillance parentale par défaut d'un service de canaux virtuels, le cas échéant, en fonction du deuxième élément analysé, l'analyse du troisième élément dans le tableau de description de canaux virtuels reçu, et la gestion des cotes d'évaluation en fonction du type de système de contrôle parental selon le troisième élément analysé.
