Abstract

Dans un mode de réalisation, un dispositif monté sur la tête (HMD) est configuré pour recevoir des données de réalité virtuelle ou de réalité augmentée (VR/AR) diffusées en continu par l'intermédiaire d'une première connexion et d'une seconde connexion. Les données VR/AR diffusées en continu sont commandées par un dispositif de commande qui transmet des premières données VR/AR diffusées en continu d'une source de données au HMD par l'intermédiaire de la première connexion et transmet des secondes données VR/AR diffusées en continu de la source de données au HMD par l'intermédiaire de la seconde connexion, de telle sorte que le HMD reçoive un flux continu de données VR/AR lorsque la source de données commute de la transmission des premières données VR/AR diffusées en continu à la transmission des secondes données VR/AR diffusées en continu.
