Intermediate film system

The intermediate film process was a technique for quasi Live broadcasting of television programs. The images were recorded on a special film developed immediately after shooting and then electronically scanned and sent. The intermediate film process was still used during the 1936 Olympic Games.

In practice, the motion picture camera was mounted on the roof of a truck and exposed the black and white film. The exposed film has not been wound up in the camera, but immediately conveyed via a light-tight slot into the interior of the truck, which was set up as a darkroom. There the film was developed, only a makeshift dried and placed the same in a pickup. In this way, it was the imperial post possible to transmit television images of the 1936 Summer Olympics with about one to two minutes of time offset.

This cumbersome process was necessary because at the time there were no television cameras, which would have been able to create a direct signal. The intermediate film process from an idea by Georg Oskar Schubert came about in around 1932 and became obsolete after 1937, since then were powerful television cameras with Ikonoskop tubes available.
