Texas Instruments MATRIX 3000 Vertical Frequency, Vertical Offset, Video Decoder, White Boost

	Appendix A: Glossary
Vertical Frequency	f The frequency at which images are generated. Vertical frequencies vary amongst
	sources. Also called vertical scan rate.
Vertical Offset	f The difference between the center of the projected image and the center of the
	projector lens. For clarity, offset is often expressed as the maximum amount of the
	image that can be projected above or below the lens center without degrading the
	image quality. Vertical offset ranges depend on the type of lens in use, and whether or
	not the image is offset horizontally at the same time.
Video	f The signal that is used by display devices (such as projectors) to generate an image.
	This term also refers to the output of video tape/disk players and computers.
Video Decoder	f An optional device that converts NTSC 3.58, NTSC 4.4, PAL, PAL-N, PAL-M or
	SECAM to RGB video.
Video Standard	f A specific type of video signal, such as NTSC, PAL, SECAM. This projector can
	automatically recognize and interpret the incoming standard and display accordingly.
Viewing Angle	f Screens do not reflect equally in all directions. Most light is reflected in a conical
	volume centered around the "line of best viewing". Maximum brightness is perceived
	if you are within the viewing cone defined by the horizontal and vertical viewing
	angles.
White Balance	f The color temperature of white used by the projector.
White Boost	f White Boost is an option that enables the recapture of some of the lost light from the
	transition between each segment in the color wheel.
White Field	f The area of an image that is white only. For example, a full white field is an image
	that is white everywhere. A 10% white field is a white area (usually rectangular) that
	occupies 10% of the image; the remaining 90% is black.
YCbCr	f A high-end digital component video signal.
YPbPr	f A high-end analog component video signal. Sometimes called YUV, Component, or
	Y, R-Y, B-Y, the YPbPr signal by-passes the video decoder in this projector.
YUV	f See YPbPr.

Zoom f The adjustment of image size by means of a zoom lens.
