Video Processing Facility at National Center for Experiments in Television at KQED-TV, San Francisco (c 1972) Tools
At the National Center for Experiments in Television (KQED-TV, San Francisco; c. 1972) Lawrence W. Templeton designed and built a flexible video Mixer to replace conventional two-bus switchers, using patch cords and experimental plug-in modules. The Mixer incorporated keyers, colorizers, a color modulator, an edge generator, feedback delay lines, a multi-keyer and six distribution amplifiers, and accepted inputs from two Sony DXC-2000A B/W cameras, a Sony DXC-5000 color camera and a Beck Direct Video Synthesizer. Circuit engineer Richard Stephens built a handheld remote control switcher; control was also demonstrated via Buchla Electric Music Box control voltages.
