Einheitsempfänger

In August 1939, Nazi Germany introduced the Einheits-Fernseh-Empfänger E1 (i.e. Unitary-TV-receiver E1), also called Volksfernseher (i.e. People's TV), a 441-line, 25 interlaced frames per second (or more correctly 50 fields per second) television system. The TV was presented to the public in the 16th International radio exhibition Berlin.

History

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 the start of World War II caused only about 50 devices to be installed in military hospitals and various government departments. The Berlin transmitter was destroyed by Allied bombing in November 1943.

Like British televisions of the era, the Einheitsempfänger could receive only one channel with its frequency pre-tuned at the factory to reduce construction costs.
