process the table to determine download information for at least one necessary resource identified in the table, the at least one necessary resource including the application;

download the at least one necessary resource, including the application, based on the download information included in the table; and

receive control information, the control information including the identifier associated associated with the at least one parameter;

retrieve the at least one parameter associated with the identifier from the table in response to the control information; and

cause the application to perform a function based on the retrieved at least one parameter.

13. The reception apparatus according to claim 12 , wherein the circuitry is configured to

receive content via at least one of a satellite broadcast, a cable television transmission, a terrestrial television broadcast, and the Internet, the content being associated with the application; and

output the received content for display.

14. The reception apparatus according to claim 12 , wherein the circuitry is configured to download the table from a satellite broadcast, a cable television transmission, a terrestrial television broadcast, or the Internet.
