no. 1 Embodiment approach

[0179] The first embodiment of the specification of this application relates to the improvement of how to select multiple elementary streams.

[0180] Figure 8 The internal structure of the recording medium of the first embodiment is shown. Such as Figure 8 As shown in (a), in the recording medium of the first embodiment, "index table file", "operation mode target program file", "playlist information file", "stream information file", and "stream file" are recorded.

[0181]

[0182] The index table (index table) file is management information about the entire recording medium. After being inserted into the playback device, the index table file is read first, so that the playback device uniquely identifies the disc. The index table file specifies the correspondence between each title constituting the title structure of the optical disc and the operation mode object that specifies the operation mode. The so-called title structure means that when the disc is loaded, the title (the ...

no. 2 Embodiment approach

[0433] In the first embodiment, since the sub-TS constituting the dependent-view data block is referenced based on the subclip entry ID reference, when the sub-TS is recorded separately from the main TS, it occurs when the 2D playback mode is switched to the 3D playback mode. The readout of the sub-TS is worried that the seamlessness of AV reproduction will be compromised. Therefore, this embodiment proposes an improvement to ensure that the main TS and the sub TS are written together in the playback device. Specifically, it is proposed to interweave the main TS and sub-TS, and record 2TS as one file.

[0434] As a prerequisite, briefly explain the files in the UDF file system. The file in the UDF is composed of multiple extents managed by the file entry. The "file entry" contains a "descriptor tag", an "ICB tag" and an "allocation descriptor".

[0435] The "descriptor tag" is a tag indicating that it is a file entry. There are types of tags such as file entry descriptors and s...

no. 3 Embodiment approach

[0547] In this embodiment, the data structure for multi-angle playback will be described.

[0548]

[0549] The description records the data distribution of the recording area that constitutes the multi-angle stereoscopic interleaved file.

[0550] In the recording area constituting the multi-angle interleaved file, a plurality of interleaved units are recorded. Each interleaving unit corresponds to each of the groups of the basic view data block and the dependent view data block.

[0551] In the multi-angle section, if there is a group of the basic angle data block and the dependent angle data block that should be reproduced when the angle number "=1" is set, the basic angle data block and the dependent angle data that should be reproduced when the angle number = 2 is set In the case of block group, angle number=3, the group of basic angle data blocks and dependent-angle data blocks that should be reproduced when set, angle number=4, when the group of basic angle data blocks and de...

Abstract

The recording medium 100 stores playlist information and a plurality of elementary streams. The playlist information includes a basic stream selection table and an extension stream selection table. The basic stream selection table shows elementary streams that are permitted to be played back in a monoscopic playback mode. The extension stream selection table shows elementary streams that are permitted to be played back only in a stereoscopic playback mode. The stream entry in the extension stream selection table indicates a packet identifier that is to be used by the playback device to perform demultiplexing when the playback device is in the stereoscopic playback mode and the corresponding stream number is set in the stream number register provided in the playback device.

Description

[0001] This application is a divisional application of a Chinese patent application whose filing date is February 4, 2010, the application number is 201080001056.9, and the title is "recording medium, reproduction device, integrated circuit". Technical field [0002] The present invention belongs to the technical field of 3D image and 2D image reproduction technology. Background technique [0003] The so-called 2D video is an image that captures the display screen of the display device as an X-Y plane, and is expressed by pixels on the X-Y plane, and is also called a plane observation image. [0004] In contrast, the so-called 3D video is an image with a depth in the Z-axis direction added to the pixels on the X-Y plane on the screen of the display device. The 3D image reproduces the left-view image watched with the left eye and the right-view image watched with the right eye together. These left-view and right-view images provide a stereoscopic observation effect for users to watch...
