Stereo TV System with Sterwo Sound

Stereo TV transmission is yet to appear on the scene. TV transmission normally cerries video signal accompanied by audio signal. While stereo sound transmission, popularly known as stereo radio, is well established, so far the main obstecle for stereo TV seems to be the development of a suitable stereo picture tube to display the 2 chamnel (stereo) video signals. Such 2 channel (stereo) video signals can be obtained from a pair of TV cameras suitably mounted like the eyes of an observer. The first author has suggested a stereo TV system using present day color TV receiver with a trigun shadow mask color picture tube1. In essence, in that system, a11 the phosphor dots of one color (say, red) on the picture tube screen are excited by one electronbeam in proportion to the video signal from one of the (say, right side) TV cameras of a pair of monochrome TV cameras, suitable mounted to take binocular (right and left) views of the object. Likewise, all the phosphor dots of another color (say, green) are excited by another electron beam in proportion to the video signal from the other (left side) TV camera. The third electron beam is cut off, so the third color (blue) phosphor dots are not excited.
