Abstract

Dispositif de commande (10) pour un afficheur vidéo (4) qui comporte un port de sortie configuré pour être couplé à un afficheur vidéo (4), un dispositif mémoire (12) destiné à la mise en mémoire de données représentant des préférences de visualisation d'un utilisateur, un générateur (14) d'images et un circuit (16) configuré pour activer le générateur (14) d'images lorsque l'ouverture d'une session de visualisation par l'utilisateur est détectée. Le générateur (14) d'images est couplé au dispositif mémoire (12) et produit une image portail destinée à être affichée sur l'afficheur vidéo en tant qu'écran portail (8) personnalisé. L'image portail (9) est fondée sur les données stockées dans le dispositif mémoire (12). Le circuit (16) est associé au générateur (14) d'images pour activer ce dernier (14) lors de la détection de l'ouverture d'une session de visualisation par un utilisateur, afin que ledit générateur d'images produise l'image portail (9) représentant l'écran portail (8) personnalisé.
