20090269028 | REPRODUCTION DEVICE AND PROGRAM - A playback apparatus plays back video data recorded on a recording medium such as a BD-ROM. The playback apparatus includes an interface in which a removable medium such as an SDRAM can be inserted, a detection module that detects that the removable medium is inserted, and a virtual file system. The virtual file system is used if the removable medium is detected to be inserted, if additional content such as subtitles is recorded on the removable medium, and furthermore if the additional content is associated with the video data recorded on the BD-ROM, etc. The virtual file system is used for dynamically combining the video data recorded on the BD-ROM, etc. and the additional content of the removable medium so as to play back a virtual package. | 10-29-2009 |
20100014580 | PLAYBACK APPARATUS FOR PERFORMING APPLICATION- SYNCHRONIZED PLAYBACK - 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. | 01-21-2010 |

20100061702 | REPRODUCING APPARATUS - A playback device generates a virtual package in response to a construction request made by an application. After the virtual package is thus generated, a virtual file system | 03-11-2010 |
20100142930 | PLAYBACK APPARATUS FOR PERFORMING APPLICATION-SYNCHRONIZED PLAYBACK - 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. | 06-10-2010 |
