Abstract: 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.

Abstract: When reading an AV Clip which is formed by multiplexing a plurality of elementary streams from a BD-ROM and playing back the AV Clip, an STN_table that lists an entry of each elementary stream is acquired from PlayList information on the BD-ROM. For each elementary stream shown in the STN_table, a judgment is made as to whether the elementary stream satisfies a predetermined condition. Of all elementary streams judged as satisfying the predetermined condition, an elementary stream having a highest entry in the STN_table is selected and played back.

Abstract: 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.

Abstract: 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.

Abstract: Playback device for playing back graphics stream according to stream selection table recorded on recording medium. Stream number register stores, as current stream number, one of a plurality of stream numbers written in the stream selection table. Capability register indicates capability to play back graphics. Procedure means determines playback type of graphics corresponding to the current stream number, based on the playback capability indicated by the capability register. Playback of graphics streams falls into two types: first playback type in which a monoscopic graphics stream is used; and second playback type in which a pair of left-eye graphics stream and right-eye graphics stream is used to perform a stereoscopic playback. The capability register indicates whether capability to perform the stereoscopic playback using the pair of left-eye and right-eye graphics streams is present in graphics decoder.

Abstract: A BD-ROM contains plurality of Titles which can be branched among and a Java application executable upon reproduction of each Title. Each Title has an AV Clip and an application management table. The application is a program described in a virtual-machine oriented programming language. The application management table correlates an application to an application run attribute in the corresponding Title. The run attribute may be a continuation attribute (Persistent) for continuing the application state in the branch origin or an AutoRun attribute for automatically running the application when the application is in a non-run state in the branch origin.

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.

Abstract: A moving image encoding method of encoding a moving image while switching between variable-length encoding schemes. In this method, a continuous unit to be continuously reproduced is determined (S5201), a stream is generated by encoding the moving image without switching between variable-length encoding schemes in the continuous unit (S5202), and management information is generated that includes a first flag information indicating that a variable-length encoding scheme is fixed in the continuous unit (S5204, and S5205).

Abstract: The Procedure executing unit 42 makes a judgment on which among three conditions are satisfied by each of a plurality of audio streams. The BD-ROM reproduction apparatus selects an audio stream to be reproduced in accordance with each combination of conditions that are satisfied by each audio stream. One of the conditions is that a channel attribute of an audio stream is surround and the reproduction apparatus is capable to output surround audio. If the audio stream to be reproduced conforms to an encoding method such as DTS-HD or DD/DD+ whose audio frames are composed of basic data and extended data, the judgment on whether the surround output is available is made by judging whether or not the reproduction apparatus has a capability to process the extended data.

Abstract: 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).

Abstract: The application manager 37 conducts “application signaling” when a first disc is replaced with a second disc. At this point, an application is continued if it is written in an application management table assigned to a Title played last on a first disc and also written in an application management table assigned to a Title to be played first on a second disc. On the other hand, an application is ended is it is written in the application management table assigned to the Title played last on the first disc but not written in the application management table assigned to the Title to be played first on the second disc.

Abstract: On a BD-ROM, an AVClip and a plurality of playback section information (PlayItems) are recorded. The AVClip includes a video stream multiplexed with a plurality of elementary streams. The playback section information Playable_PID_entries showing the playback start point and the playback end point in the video stream correlated with the filtering specification of each elementary stream. The filtering specification specifies whether each of the plurality of elementary streams are able to be played back or not.

Abstract: 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.

Abstract: A playback device includes a reading unit that reads extent blocks from a recording medium. A switching unit extracts a main-view stream and a sub-view stream from the extent blocks. Each stream is stored in a different read buffer. A decoding unit reads and decodes each stream from a corresponding read buffer. A time (t) required for the decoding unit to decode all data blocks in one extent block is greater than or equal to the sum (t1+t2+t3) of a time (t1) required for the reading unit to read the data blocks except for the top data block in the extent block, a time (t2) required for the reading unit to start to read the top of a next extent block from the time of finishing reading the tail of the extent block, and a time (t3) required for the reading unit to read the top data block in the next extent block.

Abstract: The application manager 37 conducts “application signaling” when a first disc is replaced with a second disc. At this point, an application is continued if it is written in an application management table assigned to a Title played last on a first disc and also written in an application management table assigned to a Title to be played first on a second disc. On the other hand, an application is ended is it is written in the application management table assigned to the Title played last on the first disc but not written in the application management table assigned to the Title to be played first on the second disc.

Abstract: A BD-ROM playback apparatus for selecting and playing back one among text subtitle streams together with a moving picture. PSR 48-61 store Decode Capability flags whose set values indicate, for each language, whether or not a decode capability is present. Procedure executing unit 20 judges whether each text subtitle stream can be displayed, by referring to each set value of flags. Stream selection unit 17 selects a text subtitle stream judged as being able to be decoded. Here, the decode capability for a language being present indicates presence of rendering capability for converting character codes of the language into bitmaps, and support capability for supporting properties of the language. The b16 to b23 in PSR 30 includes a permission flag indicating whether stream selection unit 17 is permitted to select an unsupported language for which rendering capability is present but not support capability.
