The CBS Chromacoder System
When the FCC approved the NTSC system in 1953, CBS announced
its plans to produce equipment for the new standard. A brochure titled
"Color Television Information from CBS" introduces a
"new" color television system developed by CBS. It includes
glossy 8x10 photos of both the color home receiver and the studio
equipment. Each photo has a description attached to the back. The brochure
came from the estate of a gentleman who was on the NAB board of directors
in the 1950's. Thanks to Brian Dunlop
for these pictures and the above information.
The "new" system described by CBS was the use of
its field sequential cameras (modified RCA TK-30s with color wheels) with
a new device called the Chromacoder, which took the sequential color
pictures and encoded them in the NTSC standard.
CBS used this equipment for a broadcast on
October 8, 1953. The 8x10's and captions are from the Press Kit
distributed to the invited guests who watched the CBS broadcast that day
at the Waldorf-Astoria.
