Broadcast Television Systems was a joint venture between Robert Bosch GmbH's Fernseh Division and Philips Broadcast in Breda, Netherlands formed in 1986.
Older systems are: Renaissance, Classic analog, Da Vinci Systems's: The Whiz (1982) and 888; The Corporate Communications's System 60XL (1982–1989) and Copernicus-Sunburst; Bosch Fernseh's FRP-60 (1983–1989); Dubner (1978-1985?), Cintel's TOPSY (1978), Amigo (1983), and ARCAS (1992) systems.
Later on in the 1970s, manufacturers of professional video broadcast equipment, such as Bosch (through their Fernseh division), RCA, and Ampex developed prototype digital videotape recorders (VTR) in their research and development labs.
The introduction of the Rank Cintel Mark III flying spot scanner and Bosch Fernseh FDL60, called a telecines, paved the way to shift from projector based transfer to a more gentle system, continuous transport motion, that allowed the easy transfer of negative film and print film and thus the decline of film chains.
