Abstract

La présente invention concerne, selon divers modes de réalisation, un dispositif numérique et son procédé de commande. Un procédé de commande d'un dispositif numérique selon un mode de réalisation de la présente invention peut comprendre les étapes consistant à : recevoir un signal de mise sous tension ; déterminer si une application, qui est exécutée au niveau d'un point temporel de mise hors tension avant de recevoir le signal de mise sous tension, est une application de sortie d'image ; lorsqu'il est déterminé que l'application, qui est exécutée au niveau du point temporel de mise hors tension, est l'application de sortie d'image, charger et exécuter l'application de sortie d'image ; charger et exécuter une première application de commande d'image destinée à commander une sortie d'image par le biais de l'application de sortie d'image ; charger une seconde application de commande d'image ; et, lorsque le chargement est terminé, mettre fin à la première application de commande d'image et exécuter la seconde application de commande d'image.
