Abstract
To provide an application life cycle management method for use in switching a movie work that is a playback target within a storage medium on which a plurality of movie works are stored, which is equivalent to one for use in replacement of BD-ROM discs. When a playback target is switched within a local storage on which a plurality of movie works are stored, a playback device, which includes an input unit for issuing a movie work switching request, performs processing with use of a user operation performed on the input unit as a trigger, instead of the medium status change between ejection and insertion. This allows application life cycle management equivalent to one in the case of BD-ROM disc replacement.

An application execution device for executing an application on a storage medium, the storage medium having a plurality of domains that correspond one-to-one to a plurality of disc IDs each identifying a disc medium provided by a provider,
- the plurality of domains each having stored thereon via copy from a disc medium identified by a disc ID corresponding to the domain:
- a plurality of applications;
- a plurality of playable titles;
- a plurality of application management tables that correspond one-to-one to the plurality of titles, and each indicate at least one of the plurality of applications whose life cycle is in a title corresponding to the application management table;
- and
- an index table that shows the one-to-one to correspondence between the plurality of titles and the plurality of application management tables,
- the application execution device reading an application from one of the plurality of domains and executing the read application,
- the application execution device comprising:
- a designation unit operable to designate one of the plurality of domains as a current domain;
- a playback unit operable to, in the current domain, play back one of a plurality of titles with reference to an index table;
- and
- an application manager operable to manage, in the current domain, operations of at least one application indicated by an application management table corresponding to the title that is played back, wherein
- when the designation unit switches the current domain to another one of the plurality of domains as a new current domain, the playback unit starts playing back a first play title that is to be played back firstly among a plurality of titles stored on the new current domain, and the application manager terminates operations of a disc-unbound application that has been operating before the switching of the current domain and is not indicated by an application management table corresponding to the first play title.
