Einheitsempfänger
Encyclopedia
On 1 September 1939, Germany
introduced a 441-line, 50 interlaced frames per second television
system.
The project started in 1938, associating the Reichspost
and several companies, including Bosch
, Blaupunkt
, Loewe
, Lorenz, TeKaDe and Telefunken
. The objective was to produce 10,000 units, but due to the start of World War II
only about 50 devices were installed in military hospitals and various government departments. The Berlin
transmitter was destroyed by allied bombing in November 1943.
The Einheitsempfänger is a German TV receiver from 1939. It could only receive one channel with its frequency
pre-tuned from the factory. This allowed for lower prices and made the reception of foreign channels difficult.
To date, only a few surviving and functioning units are known:
