Abstract

L'invention concerne un procédé et un dispositif de transmission de données, consistant à : vérifier dans le réseau local d'un terminal mobile des dispositifs de sortie multimédia qui correspondent à des exigences préétablies, et déterminer au moins un dispositif de sortie multimédia parmi les dispositif de sortie multimédia détectés comme étant le dispositif de sortie multimédia cible ; obtenir les informations de dispositif du dispositif de sortie multimédia cible, et utiliser l'adresse physique du dispositif de sortie multimédia cible contenue dans les informations de dispositif pour transmettre au dispositif de sortie multimédia cible une requête de connexion de communication de façon à établir une liaison de transmission de données avec le dispositif de sortie multimédia cible. Lorsqu'il est déterminé que des données doivent être transmises, des premières données à transmettre sont obtenues et sont transmises au dispositif de sortie multimédia cible au moyen de la liaison de transmission de données établie. Par utilisation de la solution technique de la présente invention, lors de la réalisation de multiples transmissions de données à un dispositif de sortie multimédia cible, un utilisateur n'a pas besoin de resélectionner le dispositif de sortie multimédia cible pour un établissement de connexion pour chaque transmission, permettant ainsi d'améliorer l'expérience d'utilisateur.
