    • An integrated circuit stores a module that executes applications that play digital streams. When the module is executed, the integrated circuit generates package information by merging files recorded on a first recording medium and a second recording medium, in accordance with merge management information, detects a plurality of playable titles from the package information, and selects one of the detected titles as a current title. The integrated circuit executes the application associated with the current title, and the executed application makes a request to update the generated package information by specifying new merge management information. The integrated circuit changes a file referenced from the newly specified merge management information to read-only before updating the package information, and at a point at which digital stream playback stops due to a current title change, the integrated circuit generates new package information by combining files recorded on the first and second recording media, in accordance with the newly specified merge management information.
    • 集成电路存储执行播放数字流的应用的模块。 当模块被执行时,集成电路根据合并管理信息合并记录在第一记录介质和第二记录介质上的文件来生成包信息,从包信息中检测多个可播放标题,并选择 检测到标题为当前标题。 集成电路执行与当前标题相关联的应用,并且所执行的应用通过指定新的合并管理信息来请求更新生成的包信息。 集成电路在更新包信息之前将从新指定的合并管理信息引用的文件改变为只读,并且在数字流重放由于当前标题改变而停止的点处,集成电路通过组合生成新的包信息 根据新指定的合并管理信息记录在第一和第二记录介质上的文件。

    • A playback apparatus for playing a digital stream in conjunction with an application includes a package management unit operable to generate package information by merging files recorded on a first recording medium and a second recording medium, in accordance with merge management information, and a selection unit operable to detect a plurality of playable titles from the package information, and select one of the detected titles as a current title. After the application requests the package management unit to update the merge management information, by specifying new merge management information, the package management unit changes a file referenced from the newly specified merge management information to read-only before updating the package information, and at a point at which digital stream playback stops due to a current title change by the selection unit, the package management unit generates new package information by combining files recorded on the first and second recording media, in accordance with the newly specified merge management information.

    • 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.
