Abstract:
1. A playback device, for playing back stereoscopic video, that plays back a video stream recorded on an optical disc and outputs played back video to a display device, the playback device comprising: a judgment unit operable to judge whether the display device is capable of stereoscopic display; a read unit operable to read out a video stream from the optical disc; a playback unit operable to play back the video stream; and a control unit, wherein the optical disc including an AV data recording area and a navigation information area, the AV data recording area has, recorded thereon, a transport stream where a plurality of first data blocks constituting a primary stream and a plurality of second data blocks constituting a secondary stream are arranged in an interleaved manner, each of the first data blocks is a source packet sequence including source packets generated by dividing and packetizing the primary stream, each of the second data blocks is a source packet sequence including source packets generated by dividing and packetizing the secondary stream, the primary stream is a video stream representing monoscopic video, the secondary stream is a video stream representing parallax video corresponding to the monoscopic video, the navigation information area has, recorded thereon, navigation information and playlist information, the navigation information including base location information and enhanced location information that is used only for stereoscopic video playback, the base location information indicates, by using source packet numbers assigned to source packets of the first data blocks, locations of areas where the first data blocks constituting the primary stream are recorded, the enhanced location information indicates, by using source packet numbers assigned to source packets of the second data blocks, locations of areas where second data blocks constituting the secondary stream are recorded, a data size of the first data blocks and a data size of the second data blocks are defined by: a first predetermined condition that allows a device, which reads out the transport stream from the optical disc with reference to the base location information, to decode and continually play back the primary stream while reading out the primary stream, and a second predetermined condition that allows a device, which reads out the transport stream from the optical disc with reference to both the base location information and the enhanced location information, to decode and continually play back both the primary stream and the secondary stream while reading out the primary stream and the secondary stream, the playlist information includes: the control unit causes the read unit to read out:
