Extensions to trigger parameters table for interactive television
First Claim
1. A method of a reception apparatus for processing triggers, comprising:
- receiving content from a content source;
displaying the received content on a display;
extracting a first trigger from closed caption data associated with the received content, the first trigger identifying a location of a trigger parameters table (TPT);
retrieving, by circuitry of the reception apparatus, the TPT based on the location identified in the extracted first trigger, the TPT identifying an application and including at least one event, the at least one event being associated with the application and one or a combination of an event identifier and a first media time of the received content;
storing the TPT in a memory of the reception apparatus; and
processing, by the circuitry of the reception apparatus, the at least one event based on one or a combination of a second trigger, identifying the location of the TPT and including the event identifier, and the first media time equaling a current media time of the received content.

Abstract
A method, computer program, and reception apparatus, and information providing apparatus. The method includes receiving content from a content source, and displaying the received content on a display. A first trigger is extracted from closed caption data associated with the received content. The reception apparatus retrieves a trigger parameters table (TPT) based on the extracted first trigger. The TPT includes at least one event associated with one or a combination of a trigger identifier and a first media time of the received content, and is stored in a memory of the reception apparatus. Further, the reception apparatus processes the event based on one or a combination of a second trigger including the trigger identifier and the first media time equaling a current media time of the received content.
