主权项

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; and 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; anda 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, wherein the first state and the second state are different states, wherein a video signal of the AV content is combined, with an image created by the application program when the application program is executed, for display on a display screen, and wherein the extraction section and the control section are each implemented via at least one processor.
