Abstract
Disclosed herein is a reception apparatus for receiving AV content, including: a receiver configured to trigger information for controlling processing associated with an application program to be executed in conjugation with a progress of the AV content; a holder configured to hold the application program; and a controller configured to control a state of a first application program depending on whether first trigger information for specifying processing associated with the first application program held in the holder as a subject of control has been received in synchronization with a predetermined reception timing.
