Dumont Duoscopic 1954 Split Screen TV

Recommended Posts

This looks like one of those "nutty" ill-conceived ideas. 

It looks like they have one ear pieces for each channel. 

And it looks like they're watching half a picture.

I wonder what the cost of this vs another tv was projected to be.  Just buying another tv seems more practical.

Not picture in picure, but two complete sets in one cabinet. The two images have cross polarized filters and are then combined by a half-silvered mirror. They are separated again by polarized filters, either large ones on stands as shown, or by wearing polarized glasses. But you are right about it being a nutty idea! Might as well have two separateTVs, period.

The other impracticality was that the two picture tubes were behind the combining mirror, so both viewers had to be close to the center line to see into the "picture cave." They should have shown them cuddling together on a sofa while ignoring each other.

And this idea made it past prototype and nearly to development?

I wouldn't call this "past prototype." Anyway, it must have had an extra deep cabinet, to accommodate the recessed picture tube.

The idea of "we'll try anything once" didn't really blossom until the Japanese got into the business and used their "hired for life" engineering staff to take lots of oddities to finished design even when it was obvious there would be no significant sales.

For example, there is the "trinescope" color set shown by Mitsubishi at the NYWF, a technique using three primary color picture tubes and mirrors, that had been used by RCA to show color pictures in the late 40s / early 50's while they were still figuring out how to make single-unit color picture tubes. Its only advantage in 1964 was that the small picture was bright enough to be seen clearly when the set was used outdoors. Its bulk and weight was totally out of proportion for a set with such a small picture, and like the DuMont Duoscopic, you had to look into a tunnel to watch it.

It's along the same level of thinking that gave us peanut butter and jelly in one jar or the latest contribution to American cuisine from Heinz--Mayochup.

Does this thing prevent arguments - or start them? :)

This sounds like one of Ralph Cramden's schemes...you know, like glow in the dark wallpaper....
