Abstract: A rewritable recording medium on which Index.bdmv is recorded in the BDMV directory. The Index.bdmv includes editability_flag and extended_ editability_flag. When the editability_flag is set ON, it indicates that the recording medium is treated as an editable medium by a legacy device which does not support recording and editing of stereoscopic video. When the editability_flag is set OFF, it indicates that the recording medium is treated as a non-editable medium by the legacy device. When the extended_editability_flag is set ON, it indicates that the recording medium is treated as an editable medium by a non-legacy device even when the editability flag is set OFF, where the non-legacy device supports recording and editing of stereoscopic video.

Abstract: 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.

Abstract: 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.

Abstract: A recording medium in which a left-view video stream and a right-view video stream are recorded in an interleaved transport stream file. The interleaved transport stream file is identified by a combination of (i) an equivalent identification number being equivalent with the file reference information and (ii) a file extension indicating that video streams are stored in the interleaved manner, the equivalent identification number. Among Extents that constitute the interleaved transport stream file, Extents constituting the left-view or right-view video stream are identified as a normal-format transport stream file by a combination of (i) the equivalent identification number being equivalent with the file reference information and (ii) a file extension indicating that video streams are stored in a normal manner.

Abstract: Whether or not underflow is being occurred or underflow is highly likely to occur is judged based on an image encoded data amount in a reception buffer at a time of the judgment or a change in the image encoded data amount with time. When the judgment is affirmative, a composite image data piece corresponding to one frame is generated by extracting an image data piece in the frame memory, decoding part of an image encoded data piece in the reception buffer and replacing part of the extracted the image data piece with the decoded part of the image encoded data piece. Composite image data pieces are repeatedly generated such that an occupancy ratio of replaced part of the image data piece increases each time a piece of the composite image data is newly generated, and the composite image data pieces are outputted in order of generation.

Abstract: To aim to increase the use efficiency of a screen on which a subtitle is displayed together with a stereoscopic image. A video shift mode is set for each subtitle. When a stereoscopic image is played back, in accordance with the video shift mode of the subtitle, a video plane is shifted upward or downward to perform cropping processing of collecting black frames provided in the upper end and the lower end of the screen in either one of the upper end and the lower end so as to save a display region of the subtitle.
