  • Patent number: 8705935
    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.

  • Patent number: 8699853
    Abstract: 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.

  • Patent number: 8687943
    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.

  • Patent number: 8676040
    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.

  • Publication number: 20140002621
    Abstract: A video processing device overlays appropriate presentation data over video images, even if the size of the display area for 3D video images differs from the size of the display area for presentation data that is to be presented with the 3D video images. The video processing device generates left- and right-view images from a 3D video stream, enlarges presentation data obtained from a relevant data stream to scale its display size to match the display size of video images, applying an offset value, which is determined to cause a specific parallax, to the thus enlarged presentation data to generate left- and right-view presentation data, and overlays the left-view presentation data over the left-view images and the right-view presentation data over the right-view images to display video images resulting from the overlaying.

  • Patent number: 8593511
    Abstract: A playback device for playing back a graphics stream in accordance with a stream selection table recorded on the recording medium. A procedure means determines a playback type of a graphics corresponding to the current stream number, based on the playback capability indicated by the capability register. The playback of graphics streams falls into two types, one of which is a first playback type in which a monoscopic graphics stream is used and the other is a 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 or not a capability to perform the stereoscopic playback by using the pair of left-eye graphics stream and right-eye graphics stream is present in the graphics decoder.

  • Patent number: 8559787
    Abstract: A Browsable SlideShow is recorded on a BD-ROM. The Browsable SlideShow includes a video stream, an audio stream and PlayList information. The video stream and the audio stream are recorded on separate areas on an optical disc. The PlayList information includes a plurality of pieces of PlayItem information, each of which has an In_time and an Out_time which specify a single piece of picture data in the video stream and a Still_time indicating a period during which the piece of picture data is still-displayed. A still period indicated by the Still_time is a length of time that is longer than or equal to a VBV-delay when reading a subsequent piece of picture data to an Elementary Buffer 5 of a playback apparatus. The VBV-delay is based on the time required for seeking between the separate areas and reading the audio stream.

  • Patent number: 8526797
    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).

  • Patent number: 8503867
    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.
