Abstract

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.
