摘要: In the Local Storage (18), a plurality of files, merge management information which specifies a file out of the plurality of files to be used in combination with what is recorded on a Read-Only recording medium, and signature information used for judging the authenticity of the merge management information. The Virtual File System unit (38) judges the authenticity of the merge management information based on the signature information. In the case where the merge management information is judged to be authentic, the Virtual File System unit (38) generates package information which indicates a new file structure obtained by adding the file specified by the merge management information to the file structure of the Read-Only recording medium.

摘要: 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.
