Patent ID: 8687943

Claim:
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, 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 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.
