Abstract

L'invention concerne un dispositif électronique et un procédé de traitement d'application de diffusion en continu dans le dispositif électronique. Un dispositif électronique selon divers modes de réalisation peut comporter: un écran tactile; un premier processeur servant à exécuter une application de diffusion en continu, et à commander des données de diffusion en continu, qui ont été reçues en provenance d'un serveur en fonction de l'exécution de l'application de diffusion en continu, pour qu'elles soient délivrées par l'intermédiaire de l'écran tactile; et un second processeur servant à traiter des données d'entrée d'utilisateur, qui ont été introduites par l'intermédiaire de l'écran tactile pendant l'exécution de l'application de diffusion en continu, pour qu'elles soient transmises au serveur en utilisant une première session d'unités de données de protocole (PDU), recevoir, en provenance du serveur, des données de diffusion en continu qui ont été traitées à l'aide d'une seconde session de PDU d'après les données d'entrée d'utilisateur, et fournir les données reçues de diffusion en continu au premier processeur. En outre, d'autres modes de réalisation, en plus de divers modes de réalisation de la présente invention, pourraient être possibles.
