  • a ManifestLink is an asset indicating another MPV file. Accordingly, when a multimedia player parses an MPV file recorded in a storage medium and plays a multimedia play list (or an asset list), since assets such as a digital picture, video, audio, text, and a document are provided by corresponding media, a user can recognize content of an album based on the play list. However, since a play list provided based on the ManifestLink asset is an index of the album, the user cannot recognize the content of the album. As a result, as ManifestLink assets increase in the asset list, it becomes more difficult for the user to find a desired album in the play list.

Abstract

L'invention concerne un procédé et un appareil de lecture d'une liste de lecture multimédia combinée à de l'audio représentant un contenu d'un album dans une application multimédia, ainsi qu'un support d'enregistrement destiné au stockage d'un programme pour l'exécution du procédé et d'un fichier MultiPhotoVidéo ou MusiquePhotoVidéo (MPV). Le procédé consiste à détecter des informations relatives à un actif combiné à de l'audio représentant le contenu de l'actif et à lire l'audio et les informations d'index de l'album en fonction des informations relatives à l'actif lorsque la liste de lecture multimédia est lue. Ainsi, un utilisateur peut reconnaître le contenu d'un album à l'aide de l'audio sans voir le contenu de l'album.
