field-sequential system

The field-sequential system was used in specialized applications long after it had been replaced for broadcast television.

By 1950 CBS had been working on its field-sequential system of color TV for a decade.

A later German patent by A. Frankenstein and Werner von Jaworski described another field-sequential system.

One field-sequential system was developed by Dr. Peter Goldmark for CBS, which was its sole user in commercial broadcasting.

Unlike CBS's field-sequential system, RCA directly encoded the color for every spot on the screen, a system known as "dot-sequential".

RCA developed the hardware for NTSC which superseded the field-sequential system as the U.S. standard in December 1953.

The CBS field-sequential system was an example of a mechanical television system because it relied in part on a disc of color filters rotating at 1440 rpm inside the camera and the receiver, capturing and displaying red, green, and blue television images in sequence.
