Page 2-5 - ... presented by the amounts of the three that must be mixed additively to produce light matching the light presented. (Any three colored lights may serve as primaries provided no one of them can be matched by a mixture of the other two. To achieve the maximum gamut of colors by additive mixture, saturated red, green, and blue primaries are commonly used.) primary colorants...
Page 2-36 - In a system of this type, colors are mutually exclusive in that a color cannot be red and green at the same time, or yellow and blue at the same time.
Page 4-29 - Fresnel-zone clearance, for which the transmission is theoretically 1 .2 dB better than in free space. Physically, this clearance is of such magnitude that the phase shift along a line from the antenna to the top of the obstruction and from there to the second antenna is about one-half wavelength greater than the phase shift of the direct path between antennas.
Page 2-41 - Blue x 0.67 0.21 0.14 y 0.33 0.71 0.08 The YIQ model capitalizes on two important properties of the human visual system: • The eye is more sensitive to changes in luminance than to changes in hue or saturation • Objects that cover a small part of the field of view produce a limited color sensation These properties form the basis upon which the NTSC television color system was developed.

Page 5-62 - The coefficients, delivered in floating point form, are 5-bit values that indicate the number of leading zeros in the binary representation of a frequency coefficient.
Page 1-38 - This compatibility allowed the system to interface with other systems at any layer, and it permitted many different applications to make use of various layers of the HDTV architecture.
Page 2-11 - Lightness, the brightness of an area judged relative to the brightness of a similarly illuminated area that appears to be white or highly transmitting (adjectives: light and dark).
