RCA 3 Channel Color System
This article describes a color system developed by RCA in 1947 that uses a flying spot scanner for a camera and a projection set with three CRTs for the receiver. The system was compatible with the NTSC black and white standard, using the same scan rates and number of lines. Three channels were required for transmission, one for each of the primary colors. RCA probably contemplated using UHF channels.
