3. The method according to claim 1 , wherein the at least one operation includes reading of predetermined information stored in a memory of the reception apparatus.
4. The method according to claim 1 , wherein the at least one operation includes providing predetermined information stored in a memory of the reception apparatus to an external device.
5. The method according to claim 1 , wherein the retrieving is performed while the television program is displayed to a user.
6. The method according to claim 1 , wherein the executing the application includes executing the application in synchronization with the television program.
7. The method according to claim 1 , further comprising receiving a third trigger included in the digital television broadcast signal that indicates that the at least one operation is to be executed by the application, in accordance with the set operation mode of the reception apparatus.
8. A non-transitory computer-readable storage medium storing instructions which, when executed by a computer, cause the computer to perform a method for executing an application, the method comprising:
receiving a digital television broadcast signal including a television program and a first trigger associated with the television program, the first trigger including a location of the application associated with the television program;
retrieving the application based on the location included in the first trigger;
setting an operation mode of the reception apparatus as a managed mode when the location of the application is managed by a source of the digital television broadcast signal, the managed mode allowing performance of at least one operation in the reception apparatus;
setting the operation mode of the reception apparatus as an unmanaged mode when the location of the application is not managed by a source of the digital television broadcast signal, the unmanaged mode inhibiting performance of the at least one operation in the reception apparatus; and
executing the application in response to a second trigger included in the digital television broadcast.
9. The non-transitory computer-readable storage medium according to claim 8 , wherein the application is configured to concurrently display additional content with the television program.
10. The non-transitory computer-readable storage medium according to claim 8 , wherein the at least one operation includes reading of predetermined information stored in a memory of the reception apparatus.
11. The non-transitory computer-readable storage medium according to claim 8 , wherein the at least one operation includes providing predetermined information stored in a memory of the reception apparatus to an external device.
12. The non-transitory computer-readable storage medium according to claim 8 , wherein the retrieving is performed while the television program is displayed to a user.
13. The non-transitory computer-readable storage medium according to claim 8 , wherein the executing the application includes executing the application in synchronization with the television program.
14. The non-transitory computer-readable storage medium according to claim 8 , further comprising receiving a third trigger included in the digital television broadcast signal that indicates that the at least one operation is to be executed by the application, in accordance with the set operation mode of the reception apparatus.
15. A reception apparatus, comprising:
circuitry configured to
receive a digital television broadcast signal including a television program and a first trigger associated with the television program, the first trigger including a location of the application associated with the television program;
retrieve the application based on the location included in the first trigger;
set an operation mode of the reception apparatus as a managed mode when the location of the application is managed by a source of the digital television broadcast signal, the managed mode allowing performance of at least one operation in the reception apparatus;
set the operation mode of the reception apparatus as an unmanaged mode when the location of the application is not managed by a source of the digital television broadcast signal, the unmanaged mode inhibiting performance of the at least one operation in the reception apparatus; and
execute the application in response to a second trigger included in the digital television broadcast.
16. The reception apparatus according to claim 15 , wherein the application is configured to concurrently display additional content with the television program.
17. The reception apparatus according to claim 15 , wherein the at least one operation includes reading of predetermined information stored in a memory of the reception apparatus.
18. The reception apparatus according to claim 15 , wherein the at least one operation includes providing predetermined information stored in a memory of the reception apparatus to an external device.
19. The reception apparatus according to claim 15 , wherein the circuitry retrieves the application while the television program is displayed to a user.
20. The reception apparatus according to claim 15 , wherein the circuitry is configured to execute the application in synchronization with the television program.
21. The reception apparatus according to claim 15 , wherein the circuitry is further configured to receive a third trigger included in the digital television broadcast signal that indicates that the at least one operation is to be executed by the application, in accordance with the set operation mode of the reception apparatus.
