1. A readout apparatus comprising:
- a selection unit operable to select, as a current title, one title from among a plurality of titles recorded on a disc; and
an application management unit operable to read an operation mode object corresponding to the current title from the disc and execute one or more applications stored on the disc based on a management table that is included in the operation mode object; and
a playback control engine operable to play back a digital stream recorded on the disc based on playlist information selected by an executed application,whereineach application is a disc-unboundary application or a title-boundary application, andwhen a 1st disc is exchanged for a 2nd disc, the application management unit(i) maintains execution of a disc-unboundary application shown in a management table included in an operation mode object corresponding to a title selected last on the 1st disc if the disc-unboundary application is also shown in a management table included in an operation mode object corresponding to a title selected first on the 2nd disc, and(ii) terminates execution of a title-boundary application when another title is selected and thus a title corresponding to an operation mode object including a management table based upon which the title-boundary application has been executed is no longer the current title.

Abstract
The application manager 37 conducts “application signaling” when a first disc is replaced with a second disc. At this point, an application is continued if it is written in an application management table assigned to a Title played last on a first disc and also written in an application management table assigned to a Title to be played first on a second disc. On the other hand, an application is ended is it is written in the application management table assigned to the Title played last on the first disc but not written in the application management table assigned to the Title to be played first on the second disc.

8. A recording method comprising:
-
recording on a 1st disc and a 2nd disc;
operation mode objects in one-to-one correspondence with a plurality of titles;
one or more applications;
a digital stream; and
playlist information for selection by the one or more applications,each of the operation mode objects includes an application management table managing one or more applications, each application managed by the application management table being a disc-unboundary application or a title-boundary application, and when the 1st disc is exchanged for the 2nd disc in an apparatus operable to reproduce the 1st and 2nd discs, the apparatus (i) maintains execution of a disc-unboundary application shown in a management table included in an operation mode object corresponding to a title selected last on the 1st disc if the disc-unboundary application is also shown in a management table included in an operation mode object corresponding to a title selected first on the 2nd disc, and (ii) terminates execution ofa title-boundary application when another title is selected and thus a title corresponding to an operation mode object including a management table based upon which the title-boundary application has been executed is no longer the current title.

9. A readout method comprising:
-
selecting, as a current title, one title from among a plurality of titles recorded on a disc; performing application management by reading an operation mode object corresponding to the current title from the disc and executing one or more applications stored on the disc based on a management table that is included in the operation mode object; and performing playback control by playing back a digital stream recorded on the disc based on playlist information selected by an application so executed, wherein each application is a disc-unboundary application or a title-boundary application, and when a 1st disc is exchanged for a 2nd disc, the application management involves (i) maintaining execution of a disc-unboundary application shown in a management table included in an operation mode object corresponding to a title selected last on the 1st disc if the disc-unboundary application is also shown in a management table included in an operation mode object corresponding to a title selected first on the 2nd disc, and (ii) terminating execution of a title-boundary application when another title is selected and thus a title corresponding to an operation mode object including a management table based upon which the title-boundary application has been executed is no longer the current title.
