Abstract

L'invention concerne un système de réseau média intelligent intégré, un lecteur média intelligent intégré, et un procédé correspondant. Ce système comprend: un centre des opérations du réseau (NOC), un réseau, un terminal de lecture, et un lecteur média intelligent intégré. Ce dernier comprend: une unité centrale, une puce de décompression, un commutateur vidéo, une mémoire. Le procédé selon l'invention comprend les étapes suivantes: le lecteur média intelligent intégré détermine les instructions envoyées à partir du terminal de lecture, et lit les fichiers média en fonction de la détermination de ces instructions, puis envoie ces instructions de commande au commutateur vidéo; ce dernier commute la sortie du lecteur média intelligent intégré sur un dispositif d'affichage, lorsqu'il reçoit les instructions de commande; une fois la lecture des fichiers média terminée, le lecteur média intelligent intégré enregistre les circonstances de la lecture dans un fichier journal, et dans le même temps, le commutateur vidéo commute la sortie vidéo du terminal de lecture sur le dispositif d'affichage.
