COMPATIBLE COLOR APPROVED FOR TV
By JACK GOULD
New York Times
New color sets
will receive both color and black-and-white programs, depending on whichever
type is broadcast.
The newly
approved color system technically involves the simultaneous transmission of two
signals. One signal represents the brightness of the picture and is the same as
the existing black-and-white signal.
The other signal represents the individual colors and their intensity. The existing monochrome receiver makes use of only the brightness signal; the color set makes use of both.
