Abstract
Abstract This invention relates to remote television channel selection and plural function apparatus comprising: A tuner for receiving a composite television signal including luminance, chrominance and audio information modulated on a carrier on any one of a plurality of channels; a demodulator connected to said tuner for providing said luminance, chrominance and audio information in a baseband format; means located at said control apparatus for manually varying the channel selection of the tuner; means located at said control apparatus for manually varying the characteristics of the baseband luminance, chrominance, and audio information as a function of viewer preference; means for remodulating and transmitting electromagnetically the composite television signal to a remotely located television receiver on an unused channel via wireless transmission; the remote control of both tuning and other receiver functions being effected without direct connection or modification to the receiver. A similar apparatus provides for remote radio channel selection for receiving radio signals. A similar apparatus provides for remote radio channel selection for receiving radio signals and means for remodulating and transmitting on an ultrasonic sound carrier. A similar apparatus provides for remote television channel selection and plural functioning in which the demodulated composite television signal is retransmitted on a carrier located in the infra-red or visible range of light frequencies.
