Patent

CA 2368456

Output obtained during playback, and operations available during playback, differ according to the content of the reproduction path being played from an optical disc storing plural reproduction paths containing plural different types of audio and/or image information. Content type information indicative of the specific audio and/or video content of each reproduction path is stored for each reproduction path on the optical disc. This information is then presented to the user on a reproduction path (program or play list) selection screen to inform the user and assist in the play list selection process. Operation of the disc player or disc editor can be changed appropriately to this content type information.

Selon l'invention, le résultat obtenu en lecture et les manipulations pouvant être effectuées pendant la lecture diffèrent en fonction du contenu de la piste en cours de lecture d'un disque optique comportant plusieurs pistes de lecture contenant différents types de données sonores et/ou d'image. Les informations sur le type de contenu sonore et/ou d'image spécifique de chaque piste de lecture sont stockées pour chaque piste dans le disque optique. Ces informations sont ensuite présentées à l'utilisateur sur un écran de sélection des pistes de lecture (programme ou liste de diffusion) pour l'informer et l'aider à la tâche de sélection de la liste de diffusion. Les fonctions du lecteur de disque ou de l'éditeur de disque peuvent ainsi être modifiées et adaptées relativement à ces informations sur le type de contenu.
