Recording medium, playback device, system LSI, playback method, glasses, and display device for 3D images

A system LSI embedded in a playback device together with a drive device that reads out a transport stream file that is identified by file reference information included in playlist information, the system LSI comprising:

• a decoder operable to obtain non-compressed picture data by decoding compressed picture data that is included in a video stream stored in the transport stream file;
• a mode register storing an output mode of the playback device;
• and
• a control unit operable to control the playback device to output the obtained non-compressed picture data in accordance with the output mode stored in the mode register, wherein
• when the output mode is a planar-view output mode, the control unit controls the drive device to read out a normal-format transport stream file that is identified by a combination of (i) the file reference information included in the playlist information and (ii) a file extension indicating that video streams are stored in a normal manner, and
• when the output mode is a stereoscopic-view output mode, the control unit controls the drive device to read out an interleaved transport stream file that is identified by a combination of (i) the file reference information included in the playlist information and (ii) a file extension indicating that video streams are stored in an interleaved manner.

A playback method for performing, on a computer, a process of playing back a video stream in accordance with playlist information, the playback method comprising the steps of:

• reading out a transport stream file from a recording medium, the transport stream file being identified by file reference information included in the playlist information;
• obtaining non-compressed picture data by decoding compressed picture data that is included in a video stream stored in the read-out transport stream file;
• and
• outputting the obtained non-compressed picture data in accordance with an output mode stored in a mode register of the computer, wherein
• when the output mode is a planar-view output mode, the reading step reads out a normal-format transport stream file that is identified by a combination of (i) the file reference information included in the playlist information and (ii) a file extension indicating that video streams are stored in a normal manner, and
• when the output mode is a stereoscopic-view output mode, the reading step reads out an interleaved transport stream file that is identified by a combination of (i) the file reference information included in the playlist information and (ii) a file extension indicating that video streams are stored in an interleaved manner.

A recording method for recording, onto a recording medium, playlist information and an AV stream including a left-view stream and a right-view stream, the recording method comprising the steps of:

• generating the left-view stream including a plurality of extents and the right-view stream including a plurality of extents;
• generating a file entry for a transport file in an interleave format, and recording data in which the plurality of extents belonging to the left-view stream and the plurality of extents belonging to the right-view stream are interleaved;
• recording the file entry for the transport file in the interleave format;
• generating a file entry for a transport file in a normal format, and recording the file entry;
• and
• recording the playlist information,
• wherein the playlist information includes one or more pieces of playback section information,
• the one or more pieces of playback section information include file reference information that specifies a stream file corresponding to the AV stream,
• the transport stream file in the interleave format stores both the plurality of extents belonging to the left-view stream and the plurality of extents belonging to the right-view stream, the transport stream file in the interleave format being identified by a combination of (i) an identification number which is equivalent with the file reference information and (ii) a file extension indicating being interleaved, and
• the transport file in the normal format stores a plurality of extents, which are either the plurality of extents belonging to the left-view stream or the plurality of extents belonging to the right-view stream and belong to a base-view stream which can be played back independently, the transport file in the normal format being identified by a combination of (i) the identification number which is equivalent with the file reference information and (ii) a file extension indicating being the normal format.

A recording medium playback system comprising a recording medium and a playback device for playing back the recording medium,

• the recording medium having playlist information and stream files recorded thereon,
• wherein the playlist information includes one or more pieces of playback section information,
• the one or more pieces of playback section information include file reference information that specifies the stream files storing video streams,
• the stream files are an interleaved transport stream file and a normal-format transport stream file,
• in the interleaved transport stream file, a plurality of segments belonging to a left-view video stream and a plurality of segments belonging to a right-view video stream are arranged in an interleaved manner, the interleaved transport stream file being identified by a combination of an equivalent identification number and a file extension indicating that video streams are stored in the interleaved manner, the equivalent identification number being equivalent with the file reference information, and
• the normal-format transport stream file stores a base-view video stream, and is identified by a combination of the equivalent identification number and a file extension indicating that video streams are stored in a normal manner, the base-view video stream being either the left-view video stream or the right-view video stream that can be played back in a planar-view playback,
• the playback device including:
• a reading unit operable to read out a transport stream file from a recording medium, the transport stream file being identified by file reference information included in the playlist information;
• a decoder operable to obtain non-compressed picture data by decoding compressed picture data that is included in a video stream stored in the read-out transport stream file;
• a mode register storing an output mode of the playback device;
• and
• an output unit operable to output the obtained non-compressed picture data in accordance with the output mode stored in the mode register,
• wherein when the output mode is a planar-view output mode, the reading unit reads out a normal-format transport stream file that is identified by a combination of (i) the file reference information included in the playlist information and (ii) a file extension indicating that video streams are stored in a normal manner, and
• when the output mode is a stereoscopic-view output mode, the reading unit reads out an interleaved transport stream file that is identified by a combination of (i) the file reference information included in the playlist information and (ii) a file extension indicating that video streams are stored in an interleaved manner.
