Glossary
Brightness. The balance of light and dark shades in an image.
Component video. The recording and transmission of video using 
separate red, green, blue and synchronization signals. 
Composite video. A type of video signal that encodes picture, 
luminance, and synchronization information so it can be carried in one 
signal.
Contrast. A measure of the tonal differences between the highlights 
and shadows of an image. In a high-contrast image, light areas are very 
bright and dark areas are very dark, with relatively few levels of gray 
between white and black. Contrast is decreased by adding grays.
NTSC. A 525-line video broadcast format developed by the National 
Television Standards Committee. NTSC is widely used in North 
America, Mexico, and Japan.

used in Western Europe, India, China, Australia, New Zealand, and 
parts of Africa.
Point. A measurement of drawn or printed objects. One point equals 
1/72 inch.
Resolution. A measure of the amount of detail contained in an image. 
Resolution can be measured in dots per inch or in pixels. Image 
sharpness and clarity improve as resolution increases.
RGB. A type of color scheme that defines color as percentages of red, 
green, and blue.
S-Video. A type of video signal used in S-VHS videotape formats. It 
transmits luminance and color separately.
SECAM (System Electronique pour Couleur Avec Memoire). A 
625-line TV system used in France, Eastern Europe, Russia, and parts 
of Africa.
Sleep mode. A power-saving feature in which the projection lamp is 
turned off when the projector has not been used for 30 minutes. In 
sleep mode, only a minimum amount of the projector’s circuitry 
remains on.
SVGA. Super Video Graphics Array. SVGA provides higher resolution 
than VGA.
SXGA. Super Extended Graphics Array. SXGA provides higher 
resolution than XGA.
