Abstract: A system interactively controlled by a TV viewer remote control transmitter displays current or future programming information superimposed over the normal programming displayed on any channel accessible to the viewer's display screen. Identification signal data are accessed and generated by the computer for durations defined in the identification signal data either automatically or in response to the TV viewer remote. Information signal data are accessed and generated by the computer in response to the TV viewer remote. A signal combiner superimposes the identification signal or the information signal over the viewer usable signal of any selected channel from the tuner. The identification signal may include data defining an icon or textual matter alerting a viewer to the availability of information data.

Abstract: The tap antenna unit includes signal splitting circuitry, coupled to a coaxial cable which is servicing a consumer electronic device, such as a television set, for splitting off a signal from the coaxial cable; a filter coupled to an output of the signal splitting circuitry for selecting a low-level sharp frequency band in the energy spectrum of the coaxial cable; circuitry for demodulating a signal carried by the low-level frequency band; circuitry for modulating the output signal onto a carrier in an unlicensed frequency band; and an output antenna which is coupled to the modulating circuitry and which is capable of transmitting the output modulated signal over a limited transmitting-receiving area.
