Early Color Television

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. A 1954 Radio Electronic Engineering article describes the system. General Electric also provided equipment for Chromacoder.

This General Electric one-tube color camera was made in 1954 for use with the Chromacoder system.
