Abstract

Selon l'invention, un dispositif terminal lit un contenu enregistré dans une unité d'enregistrement. Dans le dispositif terminal, une unité d'acquisition acquiert, à partir d'un serveur interne, des informations concernant le contenu enregistré dans l'unité de mémoire et enregistre ces informations dans l'unité de mémoire. Le serveur interne utilise le même protocole que celui utilisé par un dispositif de serveur externe pour fournir des informations concernant le contenu, et fournit à l'unité d'acquisition les informations concernant le contenu enregistré dans l'unité de mémoire. L'unité d'acquisition affiche, sur un dispositif d'affichage, les informations concernant le contenu acquis par le dispositif de serveur interne ou externe.
