Abstract

A method, non-transitory computer-readable storage medium, and reception apparatus for processing one or more triggers associated with audio/video (A/V) content, and an information providing apparatus for providing the one or more triggers. The method includes receiving by the reception apparatus the A/V content and a first trigger associated with the received A/V content. Further, the reception apparatus retrieves a trigger parameters table (TPT), associated with the A/V content, from a TPT server identified in the received first trigger. The TPT defines at least one event associated with the A/V content and defines, for each of the at least one event, a parameter used to perform a process and corresponding to the respective event.
