Abstract

L'invention se rapporte au domaine des terminaux multimédias et spécifiquement à un procédé et un dispositif de partage de données multimédias. Le procédé comprend les étapes consistant à : stocker, dans un processus de lecture d'un fichier multimédia, des données multimédias dans le fichier multimédia ; transmettre, lors de la détection d'une opération de partage, l'instruction de partage à un second appareil terminal, l'instruction de partage contenant des informations de point de départ de lecture et un identifiant de fichier du fichier multimédia ; recevoir une requête d'acquisition de données multimédias du second appareil terminal, la requête d'acquisition de données multimédias contenant les informations de point de départ de lecture et l'identifiant de fichier ; et transmettre, conformément à la requête d'acquisition multimédia, les données multimédias au second appareil terminal. Dans le mode de réalisation, en stockant des données multimédias dans un fichier multimédia pendant un processus de lecture du fichier multimédia, le premier appareil terminal peut partager le fichier multimédia au second appareil terminal et transmettre directement les données multimédias stockées au second appareil terminal, de façon à permettre au second appareil terminal de démarrer rapidement la lecture du fichier multimédia, améliorant ainsi la continuité du processus de lecture.
