History of Television
This was the first television !
Radiovision : In the 1920's,
radio made its first steps, and some inventors
got ambitious ideas to transmit live moving images. Most of them took the NIPKOW
as a scanning device. Some
PIONEERS such as J.L. BAIRD, DENES MIHALY,
Barthélémy, Jenkins and others researched in their
laboratories to enable
Baird called it "TheTelevisor " and
Mihaly "Telehor". As most radio sets in those days were self
made, the first television for the public was sold in a KIT .
TeKaDe (Telefon Kabel und Drahtwerke at Nurenberg had
Mihaly's patent) made the Telehor in a dual system version. The kit contained
two discs, the one was destined for English transmissions (vertical scanned)
and the other for the German ones (horizontal). The diameter of
the discs were smaller (13") than the televisor reducing the picture to
4 x 3 cm. The Telehor disc disposed of 60 holes over two spirals
for mechanical framing of the picture.
In USA Jenkins commercialized his mechanical
television in kits.
