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： An image coding method for properly handling a 3D video format including a base layer and an enhancement layer includes a video layer and a system layer. The video layer includes a step (S1801) of coding an image to generate a coded stream. The system layer includes a step (S1802) of multiplexing the coded stream and an identifier to generate a system stream, the identifier indicating whether or not the image has a left-right mixed format that includes a base layer and an enhancement layer and that has a left view image area and a right view image area in each picture. In the coding step (S1801), the image that includes the base layer and the enhancement layer and that has the left view image area and the right view image area in each picture is coded to generate the coded stream, when the image has the left-right mixed format.

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： 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.

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.
