Excerpt: Color television is the technology and practices associated with television's transmission of moving images in color. In its most basic form, a color broadcast can be created by broadcasting three monochrome images, one each in the three colors of red, green and blue (RGB). When displayed together or in fast succession, these images will blend together to produce a single color as seen by the viewer. One of the great technical challenges of introducing color broadcasting was the desire to reduce the high bandwidth, three times that of the existing black-and-white (B&W) standards, into something more acceptable that would not use up most of the available radio spectrum. After considerable research, the NTSC introduced a system that encoded the color information separately from the brightness, and greatly reduced the resolution of the color information in order to conserve bandwidth. The brightness image remained compatible with existing B&W television sets, at slightly reduced resolution, while color televisions could decode the extra information in the signal and produce a limited-color display. The higher resolution B&W and lower resolution color images combine in the eye to produce a seemingly high resolution color image. The NTSC standard represents a major technical achievement. Although introduced in the U.S. in the 1950s, only a few years...
