Du Mont "Duoscopic" Television Receiver |
||
The Duoscope, as presented in a 1954 issue of Radio-News magazine, was a pretty neat concept - sort of like a picture-in-picture (PiP) scheme for television, only in a way much better. Whereas PiP provides only a partial screen for each television program, Du Mont's "Duoscopic" viewer somehow received two independent signals and combined them on the screen in such a manner that there was both a horizontally polarized for one show and a vertically polarized image for the other. The viewer selected which picture to watch by wearing the appropriately polarized glasses or by watching through a floor-mounted transparent, polarized screen. I suppose that while wearing glasses, tilting you head resulted in a mixture of both programs, so the fixed screen would be the best option. The superimposed image on the CRT looked a lot like a virtually indiscernible 3-D picture as seen without colored glasses. Similarly, the audio for each program was selectable using a remote (wired) switch box. Headphones were used to provide private listening. The Duoscope turned out to be just another "outside the box" concept that never played out in the consumer world. Du Mont "Duoscopic" Television Receiver
