Abstract

Selon la fonction CEC existante, pour choisir soit d'utiliser la fonction « One Touch Play » pour afficher, par contrainte, une fenêtre en mode plein écran, soit d'utiliser une fonction qui permet d'afficher deux ou plus de deux fenêtres pour n'afficher une image que dans une de ces fenêtres, il est nécessaire d'effectuer un réglage côté téléviseur au moyen d'une télécommande ou d'un dispositif similaire, au prix de beaucoup de temps et d'efforts. Selon l'invention, outre un message qui est transmis à partir d'un côté dispositif source pendant l'utilisation de la fonction « One Touch Play », un message qui signifie « n'afficher, par contrainte, une image transmise à partir du dispositif source que dans une de la pluralité de fenêtres » est produit. Si un dispositif récepteur qui a reçu ce message est doté d'une fonction d'affichage de plusieurs fenêtres, le dispositif récepteur affiche, dans seulement une des plusieurs fenêtres, l'image d'un terminal d'entrée qui est connecté au dispositif source qui est la source de transmission du message, tout en continuant à afficher dans les autres fenêtres les images qui y sont déjà affichées.
