A bit of history. The first color TV system approved by the FCC was from
CBS, which involved a color wheel in front of the CRT, or a belt going
around the whole tube. This limited the CRT size, of course, and either
slowed the refresh rate or demanded more transmission bandwidth. In a
As Hoyte Stearns pointed out, upcoming DLP projection televisions
will use an array of lasers instead of a bright light and color wheel. See:

projection is an increased richness in
Part of the encoding process in compatable color television is

color space diagram with coordinates of chrominance and luminance. This is
also used in JPEG encoding. The spectral sensitivity of the camera,
