Stereoscopic color television system

DETAILED DESCRIPTION I claim: 1.
A stereoscopic color television transmission method comprising the steps of: photographing an object by five video cameras each of which generates a color signal and which are equidistantly spaced in the horizontal direction; transmitting video information detected by the central camera in substantially the same method as the transmission method used in a given color television system having assigned channels at certain reference frequencies and a certain color subcarrier frequency; and transmitting four video difference signals, using a composite video difference signal carrier wave which has been generated by amplitude modulating positive halfwaves and negative halfwaves of each of two currents having a phase difference of 90.
degree.
with four video difference signals generated by subtracting the video signal detected by the central camera from the other four video signals detected by the other four cameras and synthesizing the positive and negative halfwaves.
2.
A method according to claim 1, including placing said composite video difference signal carrier wave within the sideband on the opposite side of the color sub-carrier with respect to the reference frequency for an assigned channel, generating said difference signal carrier wave at 1/n (n is an integer) of the frequency of the color sub-carrier, maintaining the spectrum distribution of said carrier wave in interleaf relation with the spectrum distribution of the luminance signal from the central camera, and maintaining the bandwidth of said carrier wave within that of the channel assigned.
3.
A stereoscopic color television receiving system for reproducing and combining transmitted video difference signals, comprising: first means including an automatic phase control circuit for dividing a transmitted composite video difference signal carrier wave into two AC waves having a phase difference of 90.
degree.
; second means including a halfwave rectifier for dividing each of the two waves into a positive halfwave and a negative halfwave to provide four video difference signals; and third means including an adder circuit for adding a transmitted video signal from a central camera to each of the four video difference signals to form four corresponding video signals
