Perceptual Considerations for High-Definition Television Systems
Curtis R. Carlson, James R. Bergen · SMPTE Journal · 1984
The perceptual impact of various HDTV systems is evaluated using just-noticeable-difference analysis. The major conclusion of this analysis is that foreseeable cameras and displays will not permit effective use of luminance bandwidths beyond roughly 10 MHz in a 4:3 aspect ratio format. By exploiting the eye's reduced temporal capabilities for both high-spatial-frequency luminance and chrominance information, and by utilizing subcarrier quadrature modulation, an HDTV system seems possible whose total bandwidth is less than 10 MHz in a 5:3 format.
