摘要： A main-view and sub-view video stream pair, a graphics stream, and playlist information are recorded on a BD-ROM disc. In the sub-view video stream, metadata is provided 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 allocated to the stream number.

摘要： A base-view video stream and a dependent-view video stream are recorded on a BD-ROM. The base-view video stream includes picture data constituting a base view of a stereoscopic image. The dependent-view video stream includes offset metadata and picture data constituting a dependent view of the stereoscopic image. The offset metadata includes an offset sequence that defines an offset control of a plane memory when a graphics to be overlaid with the picture data is played back in a one-plane offset mode.

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 data broadcast display device guarantees stereoscopic perception by the user of a displayed 3D data broadcast image, while alleviating the discomfort a user experiences due to a delay in display. The data broadcast display device includes a reception unit that receives object data for generating the left-view and right-view objects, a display data generation unit that generates the left-view and right-view objects using the received object data while providing notification upon completion of the generation of each object, and a display control unit that determines, at predetermined time intervals, whether the notification has been received for both the left-view and right-view objects, includes both the left-view and right-view objects in a data broadcast image for display when determining affirmatively, and includes neither the left-view nor the right-view object in the data broadcast image for display when determining negatively.

摘要： A recording medium allows random access to be performed in playing back 3D graphics. The recording medium includes a digital stream area where a digital stream including temporally-arranged GOP pairs is recorded, and a map information area where map information is recorded. The map information indicates entry addresses in one to one correspondence with entry times on a time axis of the digital stream, and each entry address shows a beginning of a corresponding GOP pair region in the digital stream area. Each GOP pair includes first-type and second-type GOPs, wherein each first-type GOP is data indicating a plain view picture set to be played back from a corresponding entry time, and each second-type GOP is data to be played back with a corresponding first-type GOP to provide a stereoscopic view. The data indicates a difference between a stereoscopic picture set and the plain view picture set.

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 103. 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： On a BD-ROM, PlayList information is recorded. The PlayList information includes MainPath information and SubPath information. The MainPath information and SubPath information include connection_condition information and sp_connection_condition information, respectively. The connection_condition information and sp_connection_condition information indicate that, when the connection state between two MainClips referred to with the MainPath information is seamless connection (CC=5), the connection state between two SubClips referred to with the SubPath information is also seamless connection (SP_CC=5). In the case of CC=5 and sp_CC=5, IN_time of PlayItem is equal to IN_time(SubPlayItem_IN_time) of SubPlayItem.

摘要： A data recording medium by which, when encoding an externally input AV signal to an MPEG transport stream, the MPEG_TS can be quickly and efficiently converted to an MPEG program stream conforming to a DVD standard, is provided. An apparatus and method for recording to the data recording medium are also provided. A flag indicating that a first stream (such as an MPEG transport stream) is recorded in a constraint format enabling efficient conversion to a second stream (such as an MPEG program stream) is written to the management information (VOBI). By referencing this flag the recorder can easily determine if the recorded data was recorded in the specified constraint format without analyzing the data recorded to the data recording medium.

摘要： A stream generation apparatus of the present invention is a stream generation apparatus which generates a stream including coded pictures and a command for managing a buffer which holds a decoded picture, the command being added to one of the coded pictures as a reference picture. It includes a judging unit which judges whether or not the coded picture to which the command is added is skipped at the time of trick-play, an adding unit which adds, in the case where the coded picture is judged to be skipped, repetition information indicating the same contents as the command to another coded picture that follows, in decoding order, the coded picture judged to be skipped and that is not skipped at the time of the trick-play, and a generating unit which generates the stream including the coded pictures, the command and the repetition information.

摘要： A BD-ROM on which an AVClip and a Java™ application are recorded. The AVClip includes a video stream and an audio stream multiplexed therein. On the BD-ROM recorded further are management information and the Mixing_On flag corresponding to the management information. The management information indicates a playback control of the AVClip that is to be played back when the Java™ application is executed. The Mixing_On flag indicates whether or not when a user performs an operation on the Java™ application being executed while the AVClip is under the playback control, mixing of the click sound with an audio output of the AVClip is available.

摘要翻译： 记录有AVClip和Java TM应用程序的BD-ROM。 AVClip包括视频流和在其中复用的音频流。 在记录的BD-ROM上，管理信息和与管理信息对应的Mixing_On标志。 管理信息表示当执行Java TM应用时要播放的AVClip的重放控制。 Mixing_On标志指示当AVClip处于播放控制下时用户对正在执行的Java TM应用程序执行操作，是否可以将该点击音与AVClip的音频输出混合。
