Mathematical Formulations of the NTSC Color Television Signal

The NTSC color television signal specification may be presented mathematically in a variety of ways, each yielding identical total signals but using a number of different components. In this paper, the presentations are in terms of (1) two color-difference signals, (2) camera primary signals, (3) three color-difference signals, and (4) symmetrical components. The formulation of the signal specification when high-frequency components are present in the signal is also considered.
