Using a mechanical system with spinning disks and colored filters, Baird showcased the potential of color broadcasts, though this system was limited in resolution and practicality.
Peter Goldmark and CBS’s Field-Sequential System
In the 1940s, Peter Goldmark of CBS developed a field-sequential color system. This method used a rotating color wheel to display red, green, and blue images in rapid succession, which the human eye would blend into a full-color picture. While innovative, Goldmark’s system was incompatible with existing black-and-white TVs, limiting its commercial success.
The RCA and NBC Breakthrough: Compatible Color Television
The most significant leap came from RCA (Radio Corporation of America) and NBC (National Broadcasting Company), which developed an all-electronic color system compatible with black-and-white TVs. This system encoded color information in a way that black-and-white sets could still display a monochrome image, while color sets could interpret the full color signal.
In 1953, the Federal Communications Commission (FCC) officially approved the RCA-compatible color system as the standard for American television broadcasting. This marked the beginning of widespread adoption and commercial production of color TV sets.
The Technology Behind Color Television
To appreciate the invention of color television, understanding how the technology works is essential.
How Color is Produced on Screen
Color TV creates images by combining three primary colors: red, green, and blue (RGB). Each pixel on the screen is made up of tiny red, green, and blue phosphors that glow when struck by an electron beam inside the cathode-ray tube (CRT). By varying the intensity of each color, the TV can produce a wide spectrum of colors.
Color Encoding and Transmission
One of the clever aspects of color TV technology is how it encodes color information for transmission. The system uses a luminance signal (brightness) and chrominance signals (color information). The luminance signal ensures compatibility with black-and-white sets, while chrominance signals carry the color data.
This method is why old black-and-white TVs could still display a picture even after color broadcasts began, facilitating a smooth transition period.
