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.

摘要： A main-view and sub-view video stream pair, a graphics stream, and playlist information are recorded on a BD-ROM disc. In the sub-view video stream, metadata is provided in each GOP. The metadata includes a correspondence table associating offset identifiers and offset information. The offset information defines offset control for each picture in a GOP. Offset control is processing to provide a left offset and right offset for the horizontal coordinates in a graphics plane to generate a pair of graphics planes that are respectively combined with main-view and sub-view video planes. The playlist information includes a stream selection table for each playback section. When the stream selection table associates a stream number with a packet identifier of a graphics stream, one of the offset identifiers is allocated to the stream number.

摘要： A pair of main-view and sub-view video streams and a graphics stream are recorded on a BD-ROM disc. Metadata is provided in each GOP in the sub-view video stream. The metadata includes offset information. The offset information specifies offset control for a plurality of pictures constituting a GOP. Offset control is to provide a left offset and right offset for the horizontal coordinates in a graphics plane to generate a pair of graphics planes, and to combine them separately with main-view and sub-view video planes. The sub-view video stream is packetized and multiplexed in a transport stream. A header of each TS packet includes a TS priority flag. TS packets containing the metadata have a different value of TS priority flag from TS packets containing sub-view pictures.
