摘要:
The playback apparatus realizes stereoscopic viewing by overlaying planar or stereoscopic graphics over stereoscopic video in a way that reduces eye strain using following method in abstract: A graphics plane holds therein data composed of graphics data. A shift engine shifts, in a case when a composition unit composites the graphics data with a left-view video frame, coordinates of each of the pixels is shifted in a first horizontal direction, and in a case when the composition unit composites the graphics data with a right-view video frame, coordinates of each of the pixels is shifted in a second horizontal direction that is opposite to the first direction.

A recording medium 100 on which an index table, an operation mode object, and byte-code applications are recorded. The index table shows correspondence between one or more titles and one or more operation mode objects. The operation mode object includes an application management table and display rate initialization information. The application management table indicates a byte-code application to be started to a playback device when a title corresponding to the operation mode object is selected as a current title. The display rate initialization information indicates how to initialize a display rate of a display device connected to the playback device when the title corresponding to the operation mode object is selected as the current title.
摘要:
A playback time axis of a video stream is composed of a plurality of frame periods. To overlay a rendered image with a stereoscopic video image to be displayed in the i-th frame period, a process of writing to a left-view plan memory and a process of writing to a right-view plane memory both need to be completed before the start of the i-th frame period. To simultaneously request the two rendering processes, the argument of an application interface includes a pair of specifications, one specifying writing to the left-view plane memory and the other specifying writing to the right-view plane memory.

A video plane generation unit decodes stream data into a pair of left-view and right-view video planes, and outputs the pair alternately in a 3D display mode and either of the pair repeatedly in a pseudo 2D display mode. An image plane generation unit generates a pair of left-view and right-view image planes having an OSD at different horizontal locations according to its depth to be perceived, and alternately output the pair of image planes. A pseudo 2D display control unit instructs the video plane generation unit to operate in the 3D display mode and the pseudo 2D display mode in periods where the image plane generation unit does not and does output the image planes, respectively. The adder unit combines a video plane and an image plane generated by the video plane generation unit and the image plane generation unit, respectively, onto a frame, and outputs the frame.
摘要:
A plurality of contents and a BD-J object are recorded on a multi-layered BD-ROM. The plurality of contents include those that comprise a monoscopic view video, and those that comprise a stereoscopic view video. A BD-J object includes an application management table and a GUI management table. The application management table is information specifying the application to be started up to the playback apparatus, when a specific content becomes targeted for playback among the plurality of contents. A flag in the configuration information of the GUI management table indicates whether reserving a plurality of plane memories is necessary for realizing a stereoscopic view of the graphics.

A playback apparatus plays back video data recorded on a recording medium such as a BD-ROM. The playback apparatus includes an interface in which a removable medium such as an SDRAM can be inserted, a detection module that detects that the removable medium is inserted, and a virtual file system. The virtual file system is used if the removable medium is detected to be inserted, if additional content such as subtitles is recorded on the removable medium, and furthermore if the additional content is associated with the video data recorded on the BD-ROM, etc. The virtual file system is used for dynamically combining the video data recorded on the BD-ROM, etc. and the additional content of the removable medium so as to play back a virtual package.

In the Local Storage (18), a plurality of files, merge management information which specifies a file out of the plurality of files to be used in combination with what is recorded on a Read-Only recording medium, and signature information used for judging the authenticity of the merge management information. The Virtual File System unit (38) judges the authenticity of the merge management information based on the signature information. In the case where the merge management information is judged to be authentic, the Virtual File System unit (38) generates package information which indicates a new file structure obtained by adding the file specified by the merge management information to the file structure of the Read-Only recording medium.
摘要:
Ocular strain is reduced for the viewer by reducing extreme changes of depth value occurring at stereoscopic scene jumps, dimension switches from 2D to 3D video, and the like. A playback device includes a video plane and a depth value memory for storing depth values of a plurality of stereoscopic video frames. The depth value memory stores the depth values of a plurality of frames, at least including a destination frame, and of a starting frame. When a request to switch from 2D to 3D video or to switch scenes within 3D video is received, switch timing control or destination frame depth value adjustment is performed so as to reduce the occurrence of extreme depth value changes and provide smooth switching.

摘要:
In performing stereoscopic view, a shift information memory (21) stores, as a number of pixel lengths, an offset indicating how far in a right direction or a left direction to move coordinates of pixels to realize stereoscopic view. When realizing stereoscopic view, a plane shift engine (20) moves the coordinates of image data in a graphics plane in the right direction or the left direction by the number of pixel lengths indicated by the offset. When a scale of video data targeted for stereoscopic view is changed by a basic graphics plane (15), a shift distance of pixel coordinates by the plane shift engine (20) is based on a number of pixel lengths obtained by multiplying the offset by a changed scaling factor in the horizontal direction.
