    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: 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: An image decoding device is provided which is capable of decoding views coded using inter-view prediction even when decoding is not instantly completed. The image decoding device includes: a decoding processing unit (100) which decodes a second view coded with reference to a first view; and a buffer memory (900) provided upstream of the decoding processing unit (100), and when the first view and the second view are assigned with an identical decoding point in time, the decoding processing unit (100) decodes a picture of the second view at a point in time determined by adding a delay time which has a length required to complete decoding of a picture of the first view, to the decoding point in time assigned to the picture of the second view.
