Appendix A: Glossary

Variable Scan

' The ability of a projector to synchronize to inputs with frequencies within a specified

 

range.

Vertical Frequency

' The frequency at which images are generated. Vertical frequencies vary amongst

 

sources. Also called vertical scan rate.

Vertical Offset

' The difference between the center of the projected image and the center of the

 

projector lens. For this projector, this value is expressed as the maximum percentage

 

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

' 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

' An optional device that converts NTSC 3.58, NTSC 4.4, PAL, PAL-N, PAL-M or

 

SECAM to RGB video.

Video Standard

' 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

' 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

' The color temperature of white used by the projector.

White Field

' 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

' A high-end digital component video signal.

YPbPr

' A high-end analog component video signal. Sometimes called YUV, Component, or

 

Y, R-Y, B-Y, the YPbPr signal bypasses the video decoder in this projector.

YUV

' See YPbPr.
