Appendix A

Glossary

This appendix defines the specific terms used in this manual as they apply to this projector. Also included are other general terms commonly used in the projection industry.

Active Line Time

' The time, inside one horizontal scan line, during which video is generated.

Ambient Light Rejection

' The ability of a screen to reflect ambient light in a direction away from the "line of

 

best viewing". Curved screens usually have good ambient light rejection. Flat screens

 

usually have less ambient light rejection.

Analog Video

' The video output of most computers and videotape machines. Analog video can

 

generate a large number of colors.

Anamorphic

' Having or requiring a linear distortion, generally in the horizontal direction.

 

Anamorphic lenses can restore a ‘scope’ (CinemaScope) or ‘flat’ format film frame to

 

the correct wide-screen appearance by increasing its horizontal proportion.

ANSI

' The American National Standards Institute is the organization that denotes the

 

measurement standard for lamp brightness.

Aspect Ratio

' The ratio of the width of an image to its height, such as the 4:3 aspect ratio common in

 

video output. Can also be expressed as a decimal number, such as 1.77, 1.85 or 2.39.

 

The larger the ratio or decimal, the wider and “less square” the image.

Auto Source

' The ability of the projector to automatically recognize and synchronize to the

 

horizontal and vertical scan frequencies of an input signal for proper display.

Bandwidth

' The frequency range of the projector's video amplifier.

Baud Rate

' The speed (bits-per-second) at which serial communications travel from their origin.

Blanking Time

' The time inside one scan line during which video is not generated. The blanking time

 

of the input signal must be equal to or greater than the retrace time of the projector.

Brightness

' In projection, brightness usually describes the amount of light emitted from a surface

 

such as a screen. It is measured in foot-lamberts or candelas per square meter.

Candela or Candle

' Unit of measure for measuring intensity of light.

Channel

' A collection of measurements stored by the projector for a given input source,

 

including frequencies, pulse width, polarity, syncs, channel number and location, user-

 

adjustable display settings, etc. Use channels to switch between a variety of setups

 

quickly, automatically recalling previously defined display parameters.

Channel List

' A list/menu of previously-defined channels available in projector memory.
