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.
