Abstract

La présente invention concerne un dispositif de commande pour un appareil d'affichage d'image et un procédé associé, capables de relever le taux de correspondance entre chaque canal de diffusion de l'appareil d'affichage d'image (par ex., une télévision) et les informations de canal de diffusion de l'EPG (l'EPG avancé). Le dispositif de commande pour l'appareil d'affichage d'image selon les modes de réalisation de la présente invention peut comprendre une unité de commande qui détecte un canal de diffusion non mis en correspondance avec des informations de canal de diffusion lorsque les canaux de diffusion et les informations de canal de diffusion des données du guide des programmes électroniques (EPG) sont mis en correspondance les uns avec les autres, affiche, sur une unité d'affichage, la liste d'informations de canal de diffusion des données de l'EPG, qui peut être mise en correspondance avec le canal de diffusion sélectionné et non mis en correspondance, lorsque le canal de diffusion détecté et non mis en correspondance est sélectionné, et envoie les premières informations de canal de diffusion sélectionnées à un serveur en tant qu'informations de canal de diffusion qui ont été mises en correspondance avec le canal de diffusion non mis en correspondance lorsque les premières informations de canal de diffusion sont sélectionnées dans la liste d'informations de canal de diffusion affichée.
