Abstract

Un mode de réalisation de la présente invention concerne un procédé, un terminal, et un système de partage audio et vidéo d'une télévision numérique. Le procédé consiste à : convertir un signal de télévision numérique en un fichier multimédia continu; générer une liste de programmes d'après le fichier multimédia continu, la liste de programmes contenant une identification de fichier multimédia continu d'au moins un fichier multimédia continu; envoyer la liste de programmes à un terminal mobile; obtenir une identification de fichier multimédia continu cible sélectionnée par le terminal mobile d'après la liste de programmes; et envoyer un fichier multimédia continu cible correspondant d'après l'identification de fichier multimédia continu cible sélectionnée par le terminal mobile. Les modes de réalisation de la présente invention concernent également un terminal de réception de télévision numérique et un système de partage audio et vidéo d'une télévision numérique. La présente invention permet de configurer un serveur HTTP à un terminal de réception de télévision numérique et d'exécuter effectivement un partage audio et la vidéo de la télévision numérique simplement et à moindre coût.
