Abstract

L'invention concerne un procédé et un appareil de lecture de vidéo en nuage. Le procédé de lecture consiste à : initier l'accès à une vidéo devant être lue via un premier canal qui supporte un protocole en nuage; et lire la vidéo devant être lue via un second canal et la jouer, le second canal étant un canal utilisé spécialement pour transmettre des fichiers vidéo. La présente invention résout les problèmes liés à l'impossibilité de lire des vidéos ultra-haute définition dans un environnement en nuage, et à la consommation élevée de ressources informatiques d'une machine virtuelle/d'un serveur physique et de la bande passante réseau lorsque les vidéos sont lues sur un bureau virtuel. Avec la présente invention, des ressources informatiques peuvent être efficacement économisées, la consommation de la bande passante réseau peut être efficacement réduite, et l'expérience multimédia d'un utilisateur d'un bureau virtuel peut être améliorée.
