Appendix A: Glossary

Channel Number

' A number that uniquely identifies a specific channel retained in projector memory.

 

The projector can retain up to 50 channels.

Checkbox

' A menu item that indicates whether an option is currently in effect (checked) or not

 

(unchecked).

Chrominance

' The signal representing the color information (hue and saturation) when the image is

 

represented as separate chrominance and luminance. Same as “chroma”.

Color Gamut

' The range of colors allowed in a specific system, as defined within a triangular area

 

located on the CIE color locus diagram whose corners are the three primaries defined

 

in the system. Also known as color space.

Color Shift

' A change in the tint of a white field across an image.

Color Temperature

' The coloration (reddish, white, bluish, greenish, etc.) of white in an image, measured

 

using the Kelvin (degrees K) temperature scale. Higher temperatures output more

 

light.

Component Video

' See YCbCr or YPbPr.

Composite Video

' The output of video tape players and some computers, characterized by

 

synchronization, luminance and color signals combined on one output cable.

Contrast (ratio)

' The degree of difference between the lightest and darkest areas of the image.

Convergence

' The alignment of the red, green, and blue elements of a projected image so that they

 

appear as a single element.

Curved Screen

' A projection screen which is slightly concave for improved screen gain. Curved

 

screens usually have screen gains, which are greater than 1 but viewing angles much

 

less than 180°. Curved screens are not recommended for use with this projector.

DDC ' The Display Data Channel VESA standard enables communication between PCs and

 

monitors, and is based on E-EDID protocol.

DDI

' A “direct digital interface” signal can be supplied to the projector via an optional

 

digital input module installed in INPUT 5. For example, you can input an SMPTE-

 

259M signal using a Serial Digital Input Module or input an SMPTE-272M signal

 

from a Digital HDTV Serial Input Module.

DMD' Digital Micromirror Devicesused in this projector for processing red, green, and

 

blue color data.

Decoder

' Located at INPUT 3 and INPUT 4, this device converts NTSC 3.58, NTSC 4.4, PAL,

 

PAL-N, PAL-M, or SECAM to RGB video.

Detail

' The sharpness of a display from a video source.

Diffused Screen

' A type of rear-projection screen which spreads the light striking it. Screen gain is less

 

than 1 but audience viewing angles are increased.

Display Setting

' An adjustment that affects the display of an image. Such display settings include

 

contrast, brightness, tint, blanking, size, offsets, and others.
