摘要： An encoding device that, when encoding frame image groups which represent scenes respectively viewed from plurality of viewpoints over predetermined time period, generates base-view video stream by encoding frame image group of standard viewpoint without using, as reference image, any frame image of other viewpoints, generates first-type dependent-view video stream by encoding frame image group of first-type viewpoint by using, as reference image, frame image of same time of base-view video stream or of another first-type dependent-view video stream, first-type viewpoint being positioned such that at least one viewpoint is present between first-type viewpoint and standard viewpoint, and generates second-type dependent-view video stream by encoding frame image group of second-type viewpoint by using, as reference images, frame images of same time of two viewpoints sandwiching second-type viewpoint, second-type viewpoint being neither standard viewpoint nor first-type viewpoint.

摘要： A recording method for recording a base video stream and an enhancement video stream. The recording method includes: a first step of generating the base video stream by performing an irreversible conversion on an original image; and a second step of generating the enhancement video stream that includes a shift parameter and picture data. A gradation bit sequence of each pixel constituting the picture data of the enhancement video stream represents a difference between a gradation bit sequence of each pixel constituting picture data of the original image and a gradation bit sequence of each pixel constituting picture data of the base video stream. The shift parameter defines a shift operation that is performed by a playback device when the gradation bit sequence of the base video stream is added to the gradation bit sequence of the enhancement video stream.

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： A pair of main-view and sub-view video streams, a graphics stream, and playlist information are recorded on a BD-ROM disc. The sub-view video stream includes metadata arranged 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 further allocated to the stream number.
