example 1

[0338] Now, will refer to Figure 25 The flow chart description according to Figure 22 The playback processing performed by the 3D_PlayList file in .

[0339] In step S1, the controller 251 confirms that the base view video, the D1 view video, and the D2 view video are all interleaved according to the value of type.

[0340] In this case, in step S2, the controller 251 proceeds to read interleaved_file_info().

[0341] In step S3, the controller 251 judges whether or not B-D1 playback has been instructed based on a user operation or the like.

[0342] If it is judged in step S3 that B-D1 playback has been instructed, then in step S4, the controller 251 designates "10000.ilvt" (ref_to_D1-B_interleaved_file_name) described in interleaved_file_info(), and makes the UDF file system read from The optical disc 202 reads a Base view video chunk and a D1 view video chunk.

[0343] The Base view video chunk and the D1 view video chunk read by the disk drive 252 are supplied to the...

[0387] Figure 29 Another example of 3D_PlayList is shown.

[0388] Figure 29 The 3D_PlayList described in the PlayList file "00000.mpls" in the . That is, the value of type is 3.

[0389] Except that the description of SubPath is only the description of SubPath that references D2 viewpoint video and the description of interleaved_file_info(). Figure 29 The description of the 3D_PlayList in and Figure 22 Similar to the description in .

[0390] That is, SubPath_type of SubPath() is "9". SubPath_type being "9" indicates that the SubPath is a sub path for playing D2 viewpoint video.

[0391] Also, ref_to_clpi_file_name is "00002".

[0392] Figure 29 ref_to_D2-B_interleaved_file_name in interleaved_file_info() is "20000". According to this description, if D2-B is played, the reference is identified Figure 10 ilvt file "20000.ilvt" in.

[0393] Also, ref_to_D2_clpi_file_name is "00002". According to this description, if a D2 viewpoint video is played, the referenc...

[0413] Figure 33 Still another example of 3D_PlayList is shown.

[0414] Figure 33 The 3D_PlayList described in the PlayList file "00000.mpls" in the . In the optical disc 202, Base view video and D2 view video are interleaved.

[0415] The type value of PlayItem() is 3, which indicates the type of data arrangement on the optical disc 202 .

[0416] The SubPath_type of SubPath()[1] is "9". SubPath_type being "9" indicates that the first SubPath here is a subpath for playing D2 viewpoint video.

[0417] ref_to_clpi_file_name of SubPath()[1] is "00002". According to this description, if a D2 viewpoint video is played, the reference is identified Figure 10 The clpi file "00002.clpi" in.

[0418] The SubPath_type of SubPath()[2] is "8". SubPath_type being "8" indicates that the second SubPath here is a sub-path for playing D1 viewpoint video.

[0419] ref_to_clpi_file_name of SubPath()[2] is "00003". According to this description, if a D1 viewpoint video is played, it...

Abstract

The present invention relating to an information processing device, information processing method, playing device, playing method, and program that enables playing of stereo image (3D image) contents appropriately. In the case that 3D playing using Base view video and D1 view video is instructed, "10000.ilvt (ref_to_D1-B_interteaved_file_name) described in interleaved_file_info () of the PlayList file is specified, and Base view video chunks and D1 view video chunks are read out from an optical disc through a UDF file system. The Base view video chunks and D1 view video chunks that are read out are supplied to a decoder unit and played. The present invention is applicable to a playing device compatible with the BD-ROM standard.

Description

technical field [0001] The present invention relates to an information processing device, an information processing method, a playback device, a playback method, and a program, and more particularly to an information processing device, an information processing method, and a playback device that enable appropriate playback of 3D (dimensional) image content from a recording medium , playback method and program. Background technique [0002] As contents such as movies and the like, two-dimensional (2D) image contents are mainstream, but recently, three-dimensional (3D) image contents in which a stereoscopic view is realized have been paid attention to. [0003] There are various methods as a method of displaying a 3D image (hereinafter also referred to as a stereoscopic image), but when any method is used, the data amount of the 3D image is larger than that of the 2D image. [0004] In addition, high-resolution image content such as movies can be very large, so a large-capaci...
