摘要： The present invention provides a playback apparatus for playing back one combination video by combining a broadcast video with any additional video not determined by a fixed position relative to the broadcast video. The playback apparatus comprises: a first receiving unit that receives, via a broadcast wave, a broadcast video composed of broadcast images, each broadcast image being a portion of a frame image among a plurality of frame images constituting the original video; a second receiving unit that receives an additional video composed of remaining images, each remaining image being the remaining portion of the frame image; an arrangement information acquiring unit that acquires arrangement information indicating an arrangement of the broadcast image and the remaining image in the frame image; and a playback unit that reproduces and plays back the frame images by arranging the broadcast images and the remaining images based on the arrangement information.

摘要： A recording medium records a main-view stream, a sub-view stream, and management information. The management information includes a system rate for each stream, and each stream is divided into a plurality of data blocks that form a plurality of extent blocks. In each extent block, main-view data blocks and sub-view data blocks are in a continuous interleaved arrangement. A main-view data block and sub-view data block forming a single pair each have a maximum size that is determined by the following conditions: (i) the system rate of the sub-view stream, (ii) whether the pair is the top pair within the extent block, and (iii) whether a long jump region exists between the recording areas of two extent blocks that are to be read continuously.

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： 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.

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.
