Helmut Schönfelder

Helmut Schönfelder (born April 3, 1926 in Offenbach am Main ; † August 19, 2018 ) was a German engineer .

Life

Helmut Schönfelder studied electrical engineering at the TH Darmstadt from 1946 to 1952 . In 1948 he became active in the Corps Chattia Darmstadt. In 1958 he was awarded a Dr.-Ing. At the Institute for Telecommunications and High Frequency Technology. PhD. From 1955 to 1969 he was development engineer and laboratory manager at Fernseh GmbH in Darmstadt. In 1969 the Institute for Telecommunications at the TU Braunschweig was set up for him , of which he was managing director for many years from 1968 to 1992.

There he supervised about 30 doctoral theses with research topics across the entire field of television technology. Under his leadership, the Timeplex color coding process was developed, which is ideally suited for the transmission of color signals over telephone lines and satellite connections as well as for magnetic storage on miniature video recorders, and which can be described as the predecessor of the MAC process .

Schönfelder also worked in the field of television camera technology : The first cameras with CCD sensors were created at the IFT as early as 1977. Image mixing, especially Chromakey , was just as much a subject of research as the technology of the end devices.

Under his leadership, HDTV was worked on as an important research topic for many years .

Schönfelder has published his research results in numerous specialist articles and books.
