Communicating ancillary information associated with a plurality of audio/video programs

A system comprising:

• a receiver adapted to tune to an audio/video portion over a transport medium;
• a communication interface 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 indicating availability of the announcement data associated with the tuned audio/video program and the announcement data associated with the tuned audio/video content indicating enhancement data is being transmitted;
• and
• a controller adapted to redirect the announcement data to a second addressable location other than the first addressable location in response to the special announcement.

A method comprising:

• transmitting the audio/video content over a transport medium;
• multiplexing enhancement data including announcements associated with multiple audio/video programs for transmission over a separate delivery mechanism, the announcements indicating at least some of the enhancement data is being transmitted;
• and
• transmitting a predetermined indication over the separate delivery mechanism to a first addressable location at which the announcements in the enhancement data are expected, the predetermined indication being associated with one of the audio/video programs and identifying a second addressable location of one or more announcements associated with the one audio/video program.

An article comprising a machine readable tangible storage medium storing instructions that when executed cause to processor-based system to:

• transmit audio/video content over a transport medium;
• multiplex enhancement data including announcements associated with multiple audio/video programs for transmission over a separate delivery mechanism, the announcements indicating at least some of the enhancement data is being transmitted;
• and
• transmit a predetermined indication over the separate delivery mechanism to a first addressable location at which the announcements in the enhancement data are expected, the predetermined indication being associated with one of the audio/video programs and identifying a second addressable location of one or more announcements associated with the one audio/video program.
