Abstract

La présente invention concerne, dans certains modes de réalisation, un procédé et dispositif de commande de lecture de vidéos. Le procédé comporte les étapes consistant: lorsqu'un dispositif électronique met en antémémoire des données vidéo correspondant à une vidéo à lire, à obtenir une durée de lecture prédéfinie de la vidéo à lire; obtenir un débit de mise en antémémoire du dispositif électronique pour mettre en antémémoire la vidéo à lire; déterminer une durée de mise en antémémoire initiale de la vidéo à lire d'après la durée de lecture prédéfinie et le débit de mise en antémémoire; et lorsque la durée de mise en antémémoire des données vidéo de la vidéo à lire est égale à la durée de mise en antémémoire initiale, lire les données vidéo de la vidéo à lire mise en antémémoire par le dispositif électronique. De cette façon, les problèmes d'un gaspillage de ressources et d'une longue durée d'attente d'un utilisateur, causés par une trop grande quantité de vidéo à lire mise en antémémoire, peuvent être efficacement empêchés, et des à-coups et d'autres phénomènes résultant d'une trop petite quantité de vidéo à lire mise en antémémoire lorsque l'utilisateur visualise la vidéo à lire peuvent également être évités.
