Abstract
A system and method for managing interactive program and commercial content is disclosed. The system includes an interactive enabling device for receiving a broadcast stream containing interactive program and commercial triggers for retrieving interactive program and commercial content. An interactive content server communicates with a control application in the interactive enabling device. The interactive enabling device executes the control application to manage retrieval of interactive program and commercial content from the content server in response to the interactive program and commercial triggers. The interactive control application includes a gatekeeper function for selectively retrieving interactive program and commercial content in response to recognized interactive program and commercial triggers.
