First Claim
1. A receiver for receiving transmitted AV content, the receiver comprising:
- an extraction section that extracts trigger information, transmitted together with the AV content, about control over an application program to be executed;
a control section that controls a transition of the application program from a first state to a second state based on the extracted trigger information, the first state and the second state each being one of the following;
an active state, which is a state where the application program is active; and
a suspend state, which is a state where the application program is suspended and a suspended state information indicating a status in which the application program was at the time of suspension is stored; and
a display section that combines a video signal of the AV content with an image created by the application program when the application program is executed, for display on a display screen,wherein the first state and the second state are different states.

Abstract
Disclosed herein is a receiver for receiving transmitted AV content, the receiver including an extraction section adapted to extract trigger information, transmitted together with the AV content, about control over an application program to be executed in response to the AV content, and a control section adapted to control the acquisition, registration or activation of the application program, the firing of an event in the active application program, or the suspension or termination of the active application program according to one of the following commands indicated by the extracted trigger information, namely, Pre-cache, Register, Execute, Inject_event, Suspend or Terminate.

11. A reception method for receiving transmitted AV content, the reception method comprising:
-
extracting trigger information, transmitted together with the AV content, about control over an application program to be executed; controlling a transition of the application program from a first state to a second state based on the extracted trigger information, the first state and the second state each being one of the following; an active state, which is a state where the application program is active; and a suspend state, which is a state where the application program is suspended and a suspended state information indicating a state in which the application program was at the time of suspension is stored; and combining a video signal of the AV content with an image created by the application program when the application program is executed, and displaying the combined content on a display screen, wherein the first state and the second state are different states.

12. A non-transitory computer-readable medium having embodied thereon a program, which when executed by a processor within a receiver adapted to receive transmitted AV content, the program causes the processor to control the receiver to perform a reception method comprising:
-
extracting trigger information, transmitted together with the AV content, about control over an application program to be executed; controlling a transition of the application program from a first state to a second state based on the extracted trigger information, the first state and the second state each being one of the following; an active state, which is a state where the application program is active; and a suspend state, which is a state where the application program is suspended and a suspended state information indicating a state in which the application program was at the time of suspension is stored; and combining a video signal of the AV content with an image created by the application program when the application program is executed, and displaying the combined content on a display screen, wherein the first state and the second state are different states.

13. A transmitter for transmitting AV content, comprising:
a transmission section that transmits, together with the AV content, trigger information about control over an application program to be executed by a receiver, wherein the trigger information indicates a state to which the application program should be transitioned by the receiver, the state being one of the following; a suspend state, which is a state where the application program is suspended and a suspended state information indicating a state in which the application program was at the time of suspension is stored, and when the application program is executed, a video signal of the AV content is combined with an image created by the application program and the combined content is display on a display screen. - View Dependent Claims (14, 15, 16, 20)

19. A broadcasting system comprising:
a transmitter that transmits AV content; and
a receiver that receives the transmitted AV content, whereinthe transmitter includes a transmission section that transmits, together with the AV content, trigger information about control over an application program to be executed by the receiver, and the receiver includes an extraction section that extracts the trigger information, a control section that controls a transition of the application program from a first state to a second state based on the extracted trigger information, the first state and the second state each being one of the following; an active state, which is a state where the application program is active; and a suspend state, which is a state where the application program is suspended and a suspended state information indicating a status in which the application program was at the time of suspension is stored; and a display section that combines a video signal of the AV content with an image created by the application program when the application program is executed, for display on a display screen, wherein the first state and the second state are different states.
