Abstract
The invention is a method and apparatus for simultaneously enhancing two or more unique HTML pages (information resources) using a single enhancement trigger. A content creator, (e.g., a program producer, broadcaster, affiliate, cable company, or satellite provider), embeds an enhancement trigger in a data service channel of a broadcast video signal. The embedded enhancement trigger includes a collective resource identifier that identifies two or more information resources, such as a collection of different HTML pages. The content creator can then broadcast the enhancement trigger to the several information resources to enhance them all using a single enhancement trigger.
