In the design of any new color television system, the choice of the luminance signal equation and of the two color difference components to be used is important. It would be worthwhile to carefully consider alternatives to the classic NTSC equations as the new system is almost certain to be based upon time division multiplexed chrominance and luminance components and not on a composite signal. It is important also to note that the NTSC system was developed before the invention of the video tape recorder or the concept of satellite transmission, both of which use, and will continue to use, FM with its triangular noise spectrum. It will be wise to take into consideration the effects of transmission noise in choosing both the luminance equation and the color difference components.
