6. The reception apparatus according to claim 5, wherein the circuitry is configured to:

obtain trigger information for controlling the operation of the second application, and

obtain the second control information based on the trigger information.

7. The reception apparatus according to claim 2, wherein the circuitry is configured to:

limit the use of the broadcast resource by the first application when the first application has no authority to access the broadcast resource based on broadcast permission information indicating authority to access one or more broadcast services, the first control information including the broadcast permission information.

8. The reception apparatus according to claim 7, wherein the circuitry is configured to:

continue the operation of the first application and not display the broadcast resource when the first application has no authority to access the broadcast resource.

9. The reception apparatus according to claim 7, wherein the circuitry is configured to:

terminate the operation of the first application and display the broadcast resource when the first application has no authority to access the broadcast resource.

10. The reception apparatus according to claim 7, wherein the circuitry is configured to:

obtain the first application when signature information is verified by using a predetermined certificate, the first control information including the signature information.

11. The reception apparatus according to claim 7, wherein

the broadcast permission information is specified for each broadcast service in a bitmap format.

12. A reception method for a reception apparatus, comprising:
