Abstract

L'invention concerne un appareil de génération d'écrans multiples et un procédé de configuration dynamique d'écrans multiples. L'appareil de génération d'écrans multiples peut relier une pluralité d'écrans à une pluralité de ports de sortie de manière à configurer dynamiquement la pluralité d'écrans qui fournissent de multipels contenus sur un dispositif d'affichage unique. L'appareil de génération d'écrans multiples comprend un module de traitement de services qui génère une pluralité d'écrans logiques pour l'affichage d'une pluralité de services ainsi qu'un module de sortie qui mappe une combinaison d'écrans logiques comprenant au moins un écran de la pluralité d'écrans logiques sur un port de sortie.
