Kinescope
Kinescope ˈkɪnᵻskoʊp, shortened to kine ˈkɪniː, also known as telerecording in Britain, is a recording of a television programme on motion picture film, directly through a lens focused on the screen of a video monitor. The process was pioneered during the 1940s for the preservation, re-broadcasting and sale of television programmes before the introduction of quadruplex videotape, which from 1956 eventually superseded the use of kinescopes for all of these purposes.
Geer tube
The Geer tube was an early single-tube color television cathode ray tube, developed by Willard Geer. The Geer tube used a pattern of small phosphor-covered three-sided pyramids on the inside of the CRT faceplate to mix separate red, green, and blue signals from three electron guns. The Geer tube had a number of disadvantages and was never used commercially due to the much better images generated by RCA's shadow mask system. Nevertheless, Geer's patent was awarded first, and RCA purchased an option on it in case their own developments didn't pan out.
