Perceptual Considerations for High-Definition Television Systems
The perceptual impact of various high definition television (HDTV) systems is evaluated using just-noticeable difference analysis. The major conclusion of this analysis is that foreseeable cameras and displays do not permit effective utilization of luminance bandwidths beyond roughly 10 MHz in a 4×3 aspect ratio format. Furthermore, by exploiting the eye's reduced temporal capabilities for both high spatial-frequency luminance and for chrominance information, and by utilizing subcarrier quadrature modulation, a HDTV system seems possible whose total bandwidth is less than 10 MHz in a 5×3 format.
