Three-Dimensional Spectrum and Processing of Digital NTSC Color Signals
Éric Dubois, Mahdi Sabri, J.-Y. Ouellet · SMPTE Journal · 1982
The sampling of NTSC color signals is studied with the aid of the three-dimensional spectrum. The effect of various spatio-temporal sampling patterns on the spectrum is derived and some experimental measurements are given. A number of sampling structures which allow a 2fsc horizontal sampling rate are identified, and possible reconstruction filters are described.
