Title (EN) METHOD FOR RETRIEVING DATA FROM FIRST AND SECOND STORAGE MEDIUM
(FR) PROCEDE DE RECUPERATION DE DONNEES DE PREMIER ET SECOND SUPPORTS DE STOCKAGE
Abstract:
(EN) A method for modifying data read from read-only media during playback time comprises logically merging the on-disc directory tree and an associated off-disc directory tree. A logical directory tree (L_DT) is constructed from the data retrieved from the read-only medium, wherein the structure of the logical directory tree is identical with the structure of the directory tree (D_DT) of the medium. The method allows replacing content on the disc through downloaded content, e.g. replacing an out-dated trailer stored on the disc through a downloaded trailer for a new movie. The method further allows complementing or upgrading content on the disc, e.g. by downloading a new subtitle track from the internet.
(FR) L'invention concerne un procédé de modification de données lues à partir d'un support non inscriptible pendant le temps de lecture et consistant à fusionner de manière logique l'arbre de répertoire sur disque et un arbre de répertoire hors disque associé. Un arbre de répertoire logique (L_DT) est construit à partir des données récupérées du support non inscriptible, la structure de l'arbre de répertoire logique étant identique à celle de l'arbre de répertoire (D_DT) du support. Le procédé permet de remplacer un contenu sur le disque par un contenu téléchargé, par exemple, par remplacement d'une queue de bande dépassée, stockée sur le disque, par une queue de bande téléchargée pour un nouveau film. Le procédé permet également de compléter ou de mettre à jour le contenu sur le disque, par exemple, par téléchargement d'une nouvelle piste de sous-titre à partir de l'Internet.
