Abstract

L'invention concerne un procédé et un dispositif de traitement d'affichage. Le procédé de traitement d'affichage pour récepteur comprend les étapes consistant à : obtenir une image source transmise séparément par au moins deux sources actuelles connectées à un récepteur par une connexion Wi-Fi directe ; générer une image cible comprenant chaque image source en fonction de régions cibles, sans collision mutuelle, chaque image source étant sélectionnée séparément par chaque source et la région cible correspondant à la source étant utilisée pour indiquer des informations de position de l'image source correspondant à la source dans l'image cible ; et sortir l'image cible dans un module d'affichage de manière à afficher l'image cible comprenant chaque image source sur le module d'affichage. Un mode de réalisation de la présente invention génère l'image cible en fonction de l'image source, transmise par au moins deux sources, et de la région cible correspondant à la source, sans collision mutuelle, puis l'affiche sur le module d'affichage, ce qui règle le problème consistant à n'obtenir qu'une projection « un pour un » au cours d'une technique de transmission sur écran entre de multiples terminaux sur la base de la Wi-Fi, de sorte que les données des multiples terminaux peuvent être projetées sur un dispositif d'affichage de façon à obtenir un affichage à écran divisé.
