Abstract

L'invention concerne un procédé et un appareil destinés à commander la lecture d'une vidéo d'amorçage d'un dispositif terminal. Le procédé comporte les étapes consistant à: détecter la taille d'une capacité disponible dans un dispositif terminal, et après que le dispositif terminal a été connecté à un serveur en nuage, acquérir la taille d'un fichier vidéo d'amorçage dans le serveur en nuage; déterminer si le fichier vidéo d'amorçage dans le serveur en nuage est plus grand que la capacité disponible du dispositif terminal; si non, télécharger le fichier vidéo d'amorçage dans le serveur en nuage; et après qu'il a été détecté que le fichier vidéo d'amorçage est téléchargé, lire le fichier vidéo d'amorçage pendant un processus d'amorçage. En détectant la taille d'un fichier vidéo d'amorçage dans un serveur en nuage et la taille de la capacité disponible dans un dispositif terminal, et en ne téléchargeant le fichier vidéo d'amorçage dans le serveur en nuage que lorsqu'il est déterminé que le fichier vidéo d'amorçage dans le serveur en nuage n'est pas plus grand que la capacité disponible du dispositif terminal, le problème rencontré dans l'état antérieur de la technique, où la réalisation d'une opération d'amorçage échoue, ce qui est dû au fait qu'un fichier vidéo d'amorçage ne peut pas être sauvegardé dans un dispositif terminal en raison du trop grand fichier vidéo d'amorçage, est résolu.
