Abstract

Un dispositif électronique comprenant un module de communication, un processeur et une mémoire est divulgué. Le dispositif électronique établit une communication avec un second serveur pour fournir les mêmes données de diffusion en continu que celles d'un premier serveur, sur la base d'une qualité de diffusion en continu correspondant à des caractéristiques d'un service de diffusion en continu associé au premier serveur, acquiert, à partir de chacun du premier serveur et du second serveur, des données de diffusion en continu de contenus, qui sont les mêmes que celles des contenus, et peut déterminer soit le premier serveur soit le second serveur sur la base du résultat de l'acquisition d'un score de qualité de diffusion en continu pour les données de diffusion en continu reçues en provenance de chacun du premier serveur et du second serveur. Divers autres modes de réalisation sont possibles.
