    • 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. When the bytecode application requests execution of a machine unique function of the playback device, it instructs a machine unique function control unit to perform the process via a function call by the socket communication API.

    • 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. By comparing a parallax of the foreground three-dimensional model occurring in stereoscopic playback with a parallax of the intra-texture object occurring in stereoscopic playback, the device determines depth relationship between the foreground three-dimensional model and the intra-texture object and adjusts positional relationship between the foreground three-dimensional model and the intra-texture object based on a result of the determination.
    • 图像渲染装置实现了通过合成背景三维模型和在三维建模空间中定义的前景三维模型生成的合成图像的立体观看。 纹理映射单元将背景图像数据转换为两个或更多个视点纹理,并将每个视点纹理映射到三维建模空间中的背景三维模型。 视口转换单元从两个或更多个视点纹理中的每一个提取来自与视点纹理映射的背景三维模型和来自前景三维模型的视口图像。 通过将立体重放中出现的前景三维模型的视差与立体重放中出现的纹理内对象的视差进行比较,可以确定前景三维模型与纹理内对象之间的深度关系, 基于确定结果,前景三维模型和纹理内对象之间的关系。
