  • Recording medium, playback device, integrated circuit
    Publication number: 20110033170
    Abstract: 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.

  • Playback apparatus, program, playback method
    Patent number: 7885516
    Abstract: When playing an AV Clip recorded on a BD-ROM, a judgment is made, for each elementary stream, which of a plurality of predetermined conditions the elementary stream satisfies. The plurality of predetermined conditions include (a) a condition that a playback apparatus has a capability of playing the elementary stream, (b) a language attribute of the elementary stream matches a language setting of the playback apparatus, and (c) a channel attribute of the elementary stream is surround sound and the playback apparatus has a surround output capability. The playback apparatus assigns a priority to each elementary stream based on which conditions the elementary stream satisfies, selects an elementary stream having a highest priority, and plays the selected elementary stream.

  • RECORDING MEDIUM, PLAYBACK DEVICE, AND INTEGRATED CIRCUIT
    Publication number: 20110008024
    Abstract: According to a playback device, a reading unit 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.

  • Recording medium reproduction device program, reproduction method
    Patent number: 7865060
    Abstract: A BD-ROM stores PlayList information. The PlayList information defines a playback section of each of a plurality of AV clips and includes MainPath information and SubPath information. The MainPath information designates one of the AV clips as a Main Clip and defines a portion of the Main Clip as a primary playback section. The SubPath information designates another one of the AV clips as a SubClip and defines a portion of the SubClip as a secondary playback section that is to be played back in synchronism with the primary playback section. The BD-ROM stores, the one of the AV clips designated as the SubClip along with an EP_map. The EP_map shows a plurality of entry points on the SubClip in a one-to-one correspondence with entry times on the SubClip timeline.

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.

  • RECORDING MEDIUM, PLAYBACK DEVICE, ENCODING DEVICE, INTEGRATED CIRCUIT, AND PLAYBACK OUTPUT DEVICE
    Publication number: 20100303444
    Abstract: 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.

  • RECORDING MEDIUM, PLAYBACK DEVICE, PROGRAM, PLAYBACK METHOD, AND RECORDING METHOD
    Publication number: 20100260489
    Abstract: Recorded on the recording medium (BD-ROM) is an AV stream that is obtained by multiplexing a video stream and one or more audio streams. MOVIE objects are scenarios showing playback procedures of video data described using playback device-oriented commands. In addition to the MOVIE objects, enhanced-mode scenarios (Java and WebPage objects) are also recorded on the recording medium. These enhanced-mode scenarios, each of which is described in the Java language or a markup language, show control procedures with respect to playback devices. The Java and WebPage objects are capable of taking over register setting values set by MOVIE objects, and extracting parts of video data played by MOVIE objects.

  • Reproduction apparatus, reproduction method and recording method
    Patent number: 7814422
    Abstract: A BD-ROM has recorded therein an AV Clip generated by multiplexing a video stream and a graphics stream. The graphics stream represents an interactive display to be overlayed with the video stream, and includes a sequence of three Button State groups. The interactive display includes a plurality of buttons, each of which changes from a normal state to a selected state, and from the selected state to an active state, according to a user operation. In the three Button State groups in the graphics stream, the first-order group (N-ODSs) is made of a plurality of pieces of graphics data, which represent normal states of the buttons, the second-order group (S-ODSs) is made of a plurality of pieces of graphics data, which represent selected states of the buttons, and the third-order group (A-ODSs) is made of a plurality of pieces of graphics data, which represent active states of the buttons.
