The BD-ROM includes, recorded therein, a PlayList that is composed of an AVClip and PlayList information, an application, and a BD-J Object. The application is a program that is written in a programming language for a virtual machine, and a life cycle during which the application can be executed by the virtual machine is specified. The BD-J Object contains a PlayList management table. The PlayList management table indicates a playback control of the PlayList that is performed during the life cycle simultaneously with the execution of the application.
1. A playback apparatus, comprising:
a virtual machine operable to execute an application that is recorded in a recording medium;
a playback control engine operable to play back a digital stream that is recorded in the recording medium; and
an application manager operable to cause the virtual machine to execute the application when a life cycle of the application is reached, and at a same time, to cause the playback control engine to play back the digital stream in accordance with management information that is recorded in the recording medium.
2. A computer readable recording medium in which a computer readable application, a life cycle specifying an executable period of the computer readable application, a digital stream, and management information including information indicating playback control information of the digital stream that is performed during the life cycle, are recorded, the computer readable application, the life cycle, the digital stream, and the management information being read into a computer that includes a virtual machine operable to execute the computer readable application that is recorded in the computer readable recording medium, and a playback control engine operable to play back the digital stream that is recorded in the computer readable recording medium, the computer readable recording medium, being read into the computer, causing the computer to:
cause the virtual machine to execute the computer readable application when the life cycle of the computer readable application is reached, and simultaneously
