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： An Interactive Graphics Decoder 13 decodes a graphics stream, and overlays a Page including a plurality of Buttons on a moving picture. The Interactive Graphics Decoder 13 then executes a command corresponding to one of the plurality of Buttons on the Page, to thereby perform (1) a control of switching the Page to another Page and (2) a control of specifying a Button to be set in a selected state on the other Page. A judgment is made as to whether a button number of the specified Button is invalid. If the button number is invalid, an alternative value is written in a status register.

摘要： 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.

摘要： A BD-ROM on which a VC-1 video stream and an entry map (EP_map) are recorded. The VC-1 video stream includes: (a) picture data (I/P picture) whose first fields are the intra frame coding format and whose second fields are the inter frame predictive coding format; and (b) picture data (P/I picture) whose first fields are the inter frame predictive coding format and whose second fields are the intra frame coding format. The entry map indicates entry positions (SPN) of the I/P pictures, in correspondence with playback times (PTS), but does not indicate entry positions of the P/I pictures.

摘要： Provided is a recording medium that enables seamless connection between preceding playitems which are stream data arranged prior to a position where a long jump occurs, such as a layer boundary, and succeeding playitems which are stream data arranged subsequent to the position where the long jump occurs. A block exclusively for 2D playback Ln2D is arranged succeeding a 3D extent block in which a depth map data block, a right-view data block, and a left-view data block are arranged in an interleaved manner. A 3D extent block including a block exclusively for 3D playback L3SS is arranged between the block exclusively for 2D playback and a long jump point LB. The block exclusively for 2D playback and the block exclusively for 3D playback are identical in content.

摘要： A recording medium in which a left-view video stream and a right-view video stream are recorded in an interleaved transport stream file. The interleaved transport stream file is identified by a combination of (i) an equivalent identification number being equivalent with the file reference information and (ii) a file extension indicating that video streams are stored in the interleaved manner, the equivalent identification number. Among Extents that constitute the interleaved transport stream file, Extents constituting the left-view or right-view video stream are identified as a normal-format transport stream file by a combination of (i) the equivalent identification number being equivalent with the file reference information and (ii) a file extension indicating that video streams are stored in a normal manner.

摘要： A recording medium has a hierarchical directory structure. In the directory structure, a ROOT/BDMV directory and a MoDESTxx/BDMV directory are located below a root directory. The ROOT/BDMV directory contains a BD-J application that constitutes a FirstPlayback title. The BD-J application is a program to be first executed by a playback device upon loading of the recording medium to a playback device. When executed, the BD-J application causes the playback device to display a menu for receiving a user operation of selecting the BDMV directory and executes a root change function. The root change function is to cause the playback device to recognize the selected MoDESTxx directory as a virtual root directory.

摘要： A moving image coding method that can prevent playback discontinuity without an increase in processing load during playback is provided.The moving image coding method codes a video stream that includes a first moving image and a second moving image to be overlaid on the first moving image. The moving image coding method includes: a step of determining a continuous playback section that is a group of partial sections and is subject to continuous playback, in the video stream (S5301 to S5303); a step of coding the first and second moving images in the partial sections constituting the continuous playback section, under a constraint that prevents a threshold from being changed in the continuous playback section, the threshold being used for a transparency process by a luminance key in the overlaying (S5304); and a step of generating management information including flag information which indicates that the threshold is fixed in the continuous playback section (S5305).

摘要： A stream including plural access units is recorded on an information recording medium. Each access unit has a first packet that includes basic data as well as a second packet which includes extension data related to the basic data. The basic data is data that is decodable in a completed state without using extension data, and the extension data is data for improving the quality of data generated from the basic data. The header of the first packet holds first information, which indicates that the first packet includes the basic data, and the header of the second packet holds second information which indicates that the second packet includes the extension data. This arrangement allows a decoder that decodes only basic data to process the access unit, which includes the basic data and the extension data.
