    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.

    摘要： An image coding apparatus using an encoder which places restrictions on the bit depth to codes a current image to be coded having a bit depth greater than a predetermined bit depth, and includes: a down-converter (102) which down-converts the current image into a base view image having a bit depth equal to or less than the predetermined bit depth; an MVC (multiview video coding) encoder (101) which codes the base view image and decodes the coded base view image to generate a reconstructed image; and a subtracter (103) which calculates differences between characteristics of pixel values of the pre-down-conversion current image and characteristics of the corresponding pixel values of the reconstructed image, and generates, using the calculated differences, a non-base view image having a bit depth equal to or less than the predetermined bit depth, wherein the MVC encoder (101) further codes the non-base view image.
