Abstract

This invention relates to a system providing for the remote control of video signals controlling remotely television channel selection and plural functions including tuning the composite television signal, manually varying the channel selection of the tuner, mixing of an auxiliary intelligence signal into the incoming signal when it is in the baseband format, simulation of depth picture on the television screen giving a three dimensional affect, manually varying the characteristics of the baseband luminance, chrominance and audio information as a function of viewer preference. The invention also provides for a wireless coupler for separately retrieving the auxiliary intelligence signal and reproducing it. Receiver functions are controlled without direct connection or modification to the receiver.

Claims

1. Remote television channel selection and plural function control apparatus comprising:

a 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,

b. means located at said control apparatus for manually varying the channel selection of the tuner,

c. demodulator connected to said tuner for providing said luminance, chrominance and audio information in a baseband format,

d. means comprising an auxiliary jack means located subsequent of the demodulator to facilitate the addition or mixing of an auxiliary intelligence signal into the incoming signal when it is in the baseband format,

e. means comprising circuitry means connected between said auxiliary jack means and controls, whereby said circuitry means providing a simulated debth picture giving a three dimensional affect, whereby two or more picture images of a single picture are set on a single television picture tube with the said two or more picture images stemming from two or more individual transmission means being modulated by one or more image signals of a single picture, and whereby a single signal is reproduced two or more times creating thereby two or more images of a single picture signal and feeding the said two or more created images on the television screen as one and whereby delaying one image from two or more images of the same picture on the screen and whereby using pulse switching means to alternate color or amplifiers to create a variety of three dimentional affects.

f. means located at said control apparatus for manually varying the characteristics of the baseband luminance, chrominance and audio information as a function of viewer preferance,

g. means for remodulating and transmitting electromagnetically the composite television signal to a remotly located television receiver on an unused channel via wireless transmission

h. the remote control of both tuning and other receiver functions being effected without direct connection or modification to the receiver

i. a wireless coupler providing the means for separately retrieving the said auxiliary intelligence signal and reproducing the same.

2. An apparatus of claim 1 wherein said circuitry means providing a simulated debth picture giving a three dimentional affect comprising a first amplifier feeding its output signal into two or more amplifiers connected in parallel and whereby their outputs are also connected in parallel thereby reproducing two or more pictures of a single image and whereby one of the said two or more amplifiers produces a full video signal including horizontal and vertical signals while the remainder of said amplifiers are used to provide a singnal for debth shading and whereby the said remainder amplifiers are connected to output through signal delay means, thereby delaying the signal and increasing thereby the said three dimentional affect and whereby employing pulse switching means connected to the input of said one or more amplifiers for creating a variety of special said three dimensional effects and whereby said pulse switching means alternately pulsates color changes of a color video picture giving a three dimentional affect.

3. An apparatus of claim 1 wherein said circuitry means providing a simulated debth picture giving a three dimentional affect comprising whereby a single wireless transmitted signal is recreated to two or more signals and, whereby creating a delayed signal between one or more signals from the said recreated signal thereby having an output of two or more signals at its output, said output creating said signal from a single transmitted signal whereby the means producing said two or more output signals are physically not connected at their input and not connected to one another thus eliminating interference between signals;

a modulator modulating a single signal on a transmitter, said transmitter transmitting its signal to two or more tuned amplifiers via the antennas of said transmitter and said tuned amplifiers, said two or more amplifiers amplifying the transmitted signal;

two or more demodulators demodulating the signal of said tuned amplifiers and feeding same to two or more outputs;

delay means for delaying the outputs of the said demodulator by delaying one or more of the said two or more outputs, and whereby the resulting signals are thereafter fed to a single video amplifier stage.

5. A plurality of remote control apparatuses of claim 1 wherein is provided the means located at each of said plurality of said remote control apparatuses when each one is tuned to receive signals one from the other, to receive a composite audio-video signal and remove the original audio or vidio signal from said composite audio-vidio signal and add a new audio or vidio signal and retransmitting the resulting composite audio-vidio signal wirelessly to one or more of said remote control apparatuses or receivers thereby providing the means for mixing a plurality of audio or vidio signals with a single or composite audio or vidio signal.

4. An apparatus ofclaim 1 wherein said wireless coupler comprising,

a. a tuner for receiving the composite transmitted said auxiliary intelligence signal,

b. a first demodulator connected to said tuner for providing luminance, chrominance, and audio information in a baseband format, or providing a modulated subcarrier signal,

c. a first one or more tuned amplifiers prividing amplification of the said modulated subcarrier signal

d. a second demodulator connected to said first one or more tuned amplifiers for providing said luminance, chrominance information in baseband format and audio subcarrier signal,
