Abstract

La présente invention vise à vérifier avec plus de précision si oui ou non un système de lecture prend en charge une fonction facultative ou analogue. L'invention concerne un procédé de commande de lecture pour un dispositif de lecture (101) dans un système de lecture (100) comprenant le dispositif de lecture (101) destiné à lire une vidéo, et un dispositif d'affichage (103) destiné à afficher la vidéo lue par le dispositif de lecture (101), le procédé comprenant : une première étape de vérification (S201) destinée à vérifier, en faisant appel à un premier procédé, si oui ou non le dispositif d'affichage (103) prend en charge une fonction facultative pour la lecture vidéo; et une seconde étape de vérification (S202) destinée à vérifier, en faisant appel à un second procédé différent du premier procédé, si oui ou non le dispositif d'affichage (103) prend en charge la fonction facultative, lorsqu'il n'a pas été possible de vérifier si oui ou non le dispositif d'affichage (103) prend en charge la fonction facultative en faisant appel au premier procédé.
