Abstract

According to one embodiment, an information storage medium, and the program comprises referring to a manifest from a playlist that manages playback presentation of a playback presentation object, referring to one of a markup and a script from the manifest, monitoring defining of a name corresponding to an event in the markup, and generation of an event in response to the name corresponding to the event defined in the markup using an event listener in the script, and designating function contents that execute processing when the event is generated.

Claims

1. (canceled)

2. An information playback apparatus for playing back a playback presentation object on the basis of a program stored in an information storage medium, comprising:

a reading unit configured to read the program from the information storage medium; and

a reproducing unit configured to reproduce the playback presentation object on the basis of the program,

wherein the reproducing unit refers to a manifest from a playlist that manages playback presentation of the playback presentation object on the basis of the program and refers to a markup from the manifest on the basis of the program, and executes a corresponding function on the basis of the markup when an event is generated.

3. An information playback method for playing back a playback presentation object on the basis of a program stored in an information storage medium, comprising:

referring to a manifest from a playlist that manages playback presentation of a playback presentation object on the basis of the program;

referring to a markup from the manifest on the basis of the program; and

executing a corresponding function on the basis of the markup when an event is generated.

4. A information transfer method which is configured to be applied to information read out processing from an information storage medium storing a program which refers to a manifest from a playlist that manages playback presentation of a playback presentation object on the basis of the program and refers to a markup from the manifest on the basis of the program, and executes a corresponding function on the basis of the markup when an event is generated, comprising:

transferring the markup into a file cache before the markup is presented.

5. An information processing system for playing back a playback presentation object on the basis of a program stored in an information storage medium, comprising:

a network server storing a playback information, and

an information playback apparatus playing back the playback presentation object on the basis of the program and the playback information,

wherein the network server transfers the playback information to the information playback apparatus, and

the information playback apparatus refers to a manifest from a playlist that manages playback presentation of the playback presentation object on the basis of the program and refers to a markup from the manifest on the basis of the program, and executes a corresponding function on the basis of the markup when an event is generated.

6. An information processing method for playing back a playback presentation object on the basis of a program stored in an information storage medium, comprising:

transferring a playback information from a network server to an information playback apparatus, and

playing back the playback presentation object on the basis of the program and the playback information by the information playback apparatus,

the information playback apparatus refers to a manifest from a playlist that manages playback presentation of the playback presentation object on the basis of the program and refers to a markup from the manifest on the basis of the program, and executes a corresponding function on the basis of the markup when an event is generated.

7. A displaying method for display a playback presentation object on the basis of a program stored in an information storage medium, comprising:

receiving a playback information from a network server;

referring to a manifest from a playlist that manages playback presentation of the playback presentation object on the basis of the program;

referring to a markup from the manifest on the basis of the program; and

displaying a corresponding function on the basis of the markup when an event is generated.
