1. A method of a reception apparatus for executing an application program, 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 program associated with the television program;
outputting the television program for display to a user;
retrieving the application program based on the location included in the first trigger while the television program is outputted for display to the user;
executing, by circuitry of the reception apparatus, the application program in response to a second trigger included in the digital television broadcast signal, the application program being executed so as to be synchronized with the progress of the television program;
receiving a third trigger included in the digital television broadcast signal that indicates a predetermined event to be executed by the application program;
when the application program being executed by the circuitry is determined to be of a managed type, permitting the application program to perform a function associated with the predetermined event; and
when the application program being executed by the circuitry is determined to be of an unmanaged type, prohibiting the application program from performing the function associated with the predetermined event.
