  • Patent number: 8588580
    Abstract: A bytecode processing unit provided in a playback device is platform unit 20 that reads and runs a bytecode application recorded on read-only medium 105. The playback device includes: playback control unit 10 for controlling AV playback of digital streams; and machine unique function control unit 33 for performing machine unique functions unique to the playback device, to perform a control onto a content. APIs used by the bytecode application include API for playback control function, and API for socket communication. When the bytecode application requests playback control unit 10 to control the playback, it calls the playback control API to can instruct playback control unit 10 to execute the process.

  • Patent number: 8559789
    Abstract: A playback device that creates a virtual package by combining a structural element recorded on a BD-ROM with an additional content recorded on a removable medium. The middleware in the playback device is provided with a file I/O module 34 that controls data input/output of the removable medium, in accordance with a request from an application program. When a BD-J application requests writing the structural element of the virtual package and the additional content to be written is an AV stream, the file I/O module 34 writes the structural element into one or more allocation units composed of a plurality of continuous empty logical blocks in the removable medium. When the additional content to be written is not an AV stream, it writes the additional content into a normal data area that is composed of a plurality of separately scattered empty blocks in the removable medium.

  • Publication number: 20130100132
    Abstract: An image rendering device realizes stereoscopic viewing of composite images generated by compositing background three-dimensional models and foreground three-dimensional models each defined in three-dimensional modeling space. A texture mapping unit converts background image data into two or more viewpoint textures and maps each viewpoint texture to a background three-dimensional model in the three-dimensional modeling space. A viewport conversion unit extracts, for each of the two or more viewpoint textures, a viewport image from the background three-dimensional model mapped with the viewpoint texture and from the foreground three-dimensional model.

  • Publication number: 20130044108
    Abstract: An image rendering device realizes stereoscopic viewing of a joint background image. A DIBR unit 17 applies pixel shifting to each background image constructing the joint background image and also conducts boundary processing relative to the pixel shifting. The joint background image is composed of one or more background images stitched together along their edges on a three-dimensional model. The pixel shifting is to shift pixels of each background image in the row direction. The amount of shift applied to each pixel is determined based on the depth value of a corresponding pixel of a depth image. The boundary processing is to extract pixels shifted out of the display region of a given background image as a result of pixel shifting and add the extracted pixels to an edge of another background image adjacent to the given background image in the row direction.
