EXTENSIONS TO TRIGGER PARAMETERS TABLE FOR INTERACTIVE TELEVISION

摘要

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.
