<p>The present invention provides: playlists in which information that enables 3D content that has been edited in 2D to be displayed correctly, even in 3D, is recorded; and a recording and playback device, method and medium, and a playback device and method therefor. For example, a recording and playback device, method and medium, and a playback device and method, whereby a state regarding whether or not editing in 2D has been reflected in 3D is recorded and replayed for the playlists, are provided. The recording method, whereby information is recorded on the recording medium, is characterized by comprising a step for recording audio/video streams, and a step for recording playlists that stipulate the order in which the audio/video streams are to be replayed. The recording method is further characterized in that: the playlists include user interface application information; the user interface application information includes a 3D synchronization flag representing the synchronization status of information for managing 2D compatible parts of 3D content and information for managing 3D parts; and the 3D synchronization flag is set to asynchronous status when the information for managing the 2D compatible parts is to be updated, and is set to synchronous status when the information for managing the 3D parts is to be updated.</p> |
