ABSTRACT:
A system includes a receiver and a communication interface. The receiver is adapted to tune to an audio/video portion over a transport medium. The communication interface is adapted to receive announcement data associated with the tuned audio/video content directed to a first addressable location and to receive a special announcement directed to the first addressable location. The special announcement indicates availability of the announcement data associated with the tuned audio/video program, and the announcement data is associated with the tuned audio/video content and indicates enhancement data is being transmitted. The controller is adapted to redirect the announcement data to a second addressable location other than the first addressable location in response to the special announcement.
