Patent

CA 2680118

A media player is presented that scans the media files stored on an external memory card in order to update the internal database of the player. Media manager software on a personal computer sets a dirty bit in the internal memory of the media player whenever the media files on the external memory card are altered. The media player checks the dirty bit on start up or when the memory card is inserted. If the dirty bit is set, the media player scans the media files on the memory card, updates its database, then clears the dirty bit. If the dirty bit is not set, the media player does not scan the memory card. The dirty bit is associated in the internal memory with an identifier for the memory card, allowing the use of multiple memory cards.

Cette invention concerne un lecteur multimédia conçu pour balayer les fichiers multimédia stockés sur la carte mémoire externe afin d'actualiser la base de données interne du lecteur. Un logiciel gestionnaire multimédia installé sur un ordinateur personnel établit un bit indicateur de modification dans la mémoire interne du lecteur multimédia chaque fois que les fichiers multimédia figurant sur la mémoire externe sont modifiés. Le lecteur multimédia vérifie le bit indicateur de modification lors du démarrage ou lors de l'insertion de la carte mémoire. Si le bit indicateur de modification est établi, le lecteur multimédia balaie les fichiers multimédia sur la carte mémoire, il actualise sa base de données, puis il efface le bit indicateur de modification. Si le bit indicateur de modification n'est pas établi, le lecteur multimédia ne balaie pas la carte mémoire. Le bit indicateur de modification est associé, dans la mémoire interne, à un identifiant pour la carte mémoire, cela permet l'utilisation de plusieurs cartes mémoires.
