There is disclosed an addressable advertising system comprising: 1) receiver
circuitry for receiving an incoming television signal from an external source,
generating a original baseband video signal, and transmitting the original baseband
video signal to a display associated with the addressable advertising system; 2)
a local storage device coupled to the receiver circuitry for storing a plurality
of replacement video advertisements; and 3) an advertisement controller coupled
to the receiver circuitry and the local storage device for detecting a first swap
control signal transmitted in the incoming television signal. In response to the
detection of the first swap control signal, the advertisement controller causes
the receiver circuitry to receive from the local storage device a first selected
replacement video advertisement from which the receiver circuitry generates a replacement
baseband video signal and transmits the replacement baseband video signal to the display.
