摘要： A recording medium has a main-view stream, a sub-view stream, and an extended stream recorded thereon. The main-view stream contains a main-view video stream constituting main views of stereoscopic video images, and is divided into a plurality of main-view extents arranged on the recording medium. The sub-view stream contains a sub-view video stream constituting sub-views of the stereoscopic video images, and is divided into a plurality of sub-view extents arranged on the recording medium. The extended stream contains extended data to be used in combination with the main-view stream, and is divided into a plurality of extended extents arranged on the recording medium. Between an adjacent pair of the plurality of extended extents, at least two each of the plurality of the main-view extents and the plurality of the sub-view extents are placed in a continuous, interleaved arrangement.

摘要： A data creation device performing compression encoding on first frame images showing a view from a first viewpoint and second frame images showing a view from a second viewpoint generates a stream in an MPEG-2 format, and base-view/dependent-view video streams in a format conforming to an MPEG-4 MVC format. The stream in the MPEG-2 format is generated by performing compression encoding on the first frame images. The base-view video stream is a stream of dummy data having the same number of frames as and a smaller data amount than the stream in the MPEG-2 format. The dependent-view video stream is obtained by performing compression encoding on each frame of the second frame images, with reference to a frame of the stream in the MPEG-2 format to be presented at the same time as a frame of the base-view video stream corresponding to the frame of the second frame images.

摘要： On a recording medium, stereoscopic and monoscopic specific areas are located one after another next to a stereoscopic/monoscopic shared area. The stereoscopic/monoscopic shared area is a contiguous area to be accessed both in stereoscopic video playback and monoscopic video playback. The stereoscopic specific area is a contiguous area to be accessed immediately before a long jump occurring in stereoscopic video playback. In both the stereoscopic/monoscopic shared area and the stereoscopic specific area, extents of base-view and dependent-view stream files are arranged in an interleaved manner. The extents on the stereoscopic specific area are next in order after the extents on the stereoscopic/monoscopic shared area. The monoscopic specific area is a contiguous area to be accessed immediately before a long jump occurring in monoscopic video playback. The monoscopic specific area has a copy of the entirety of the extents of the base-view stream file recorded on the stereoscopic specific area.

摘要： On a recording medium, a monoscopic video specific section and a stereoscopic video specific section are continuous immediately after an extended data specific section. A shared section includes a continuous, interleaved arrangement having one each of main-view extents, sub-view extents, and extended extents. The stereoscopic video specific section includes a continuous, interleaved arrangement of extents having one each of the main-view extents and the sub-view extents. The monoscopic video specific section includes a continuous arrangement of a copy of the main-view extent arranged in the stereoscopic video specific section. The extended data specific section includes one of the extended extents that is to be used in combination with the copy of the main-view extent arranged in the monoscopic video specific section. The shared section is accessed when stereoscopic video images are played back, when monoscopic video images are played back, and when an extended stream is used. The stereoscopic video specific section is accessed during playback of the stereoscopic video images. The monoscopic video specific section is accessed during playback of the monoscopic video images. The extended data specific section and the monoscopic video specific section are accessed when the extended stream is read, immediately before or after a long jump.
