Abstract:
A digital TV (DTV) incorporates a TV white space device capable of operating on plural TV frequencies and responsive to the DTV processor to send a signal to an interfering white space device nearby the DTV that is interfering with a TV channel being presented on the TV. The signal sent from the TV white space device to the interfering white space device alters operation of the interfering white space device so as to reduce if not eliminate the interference.
