Abstract
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.
Claims21
A recording medium in which an application, a digital stream, and management information are recorded, wherein
- the application is a program that is written in a programming language for a virtual machine,
- a life cycle during which the application can be executed by the virtual machine is specified, and
- the management information indicates a playback control of the digital stream that is performed during the life cycle simultaneously with the execution of the application.
A playback apparatus, comprising:
- a virtual machine unit operable to execute an application that is recorded in a recording medium;
- a playback control engine unit operable to playback a digital stream that is recorded in the recording medium;
- and
- an application manager operable to cause the virtual machine unit to execute the application when a life cycle of the application is reached, and at a same time, to cause the playback control engine unit to play back the digital stream in accordance with management information that is recorded in the recording medium.
A program that is read into a computer that includes a virtual machine unit operable to execute an application that is recorded in a recording medium, and a playback control engine unit operable to play back a digital stream that is recorded in the recording medium, the program causing the computer to execute the steps of:
- causing the virtual machine unit to execute the application when a life cycle of the application is reached, and at the same time
- causing the playback control engine unit to play back the digital stream in accordance with management information that is recorded in the recording medium.
A playback method for a computer that includes a virtual machine unit operable to execute an application that is recorded in a recording medium, and a playback control engine unit operable to play back a digital stream that is recorded in the recording medium, the playback method causing the computer to execute the steps of:
- causing the virtual machine unit to execute the application when a life cycle of the application is reached, and at the same time
- causing the playback control engine unit to play back the digital stream in accordance with management information that is recorded in the recording medium.
A system integrated circuit that is embedded into a playback apparatus that plays back a digital stream, the system integrated circuit comprising:
- a virtual machine unit operable to execute an application that is recorded in a recording medium;
- and
- an application manager operable to cause the virtual machine unit to execute the application when a life cycle of the application is reached, and at a same time, to cause the playback control engine unit to play back the digital stream in accordance with management information that is recorded in the recording medium.
