ö
A number that uniquely identifies a specific channel retained in projector
memory. The projector can retain up to 99 channels.
ö
A menu item that indicates whether an option is currently in effect (checked) or
not (unchecked).
ö
A change in the tint of a white field across an image.
ö
The coloration (reddish, white, bluish, greenish, etc.) of white in an image,
measured using the Kelvin (K) temperature scale. Higher temperatures output
more light.
ö
See YUV Video.
ö
The output of video tape players and some computers, characterized by
synchronization, luminance and color signals combined on one output cable.
ö
The degree of difference between the lightest and darkest areas of the image.
ö
The alignment of the red, green, and blue elements of a projected image.
ö
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
ö
'',
Direct Digital Interface signal, supplied on the projector via the optional Vista
Digital Interface. This signal is more commonly called a serial digital 4:2:2
component video (YCrCb) signal.

ö
'HWDLO
The sharpness of a display from a video source.
ö
A type of rear-projection screen which spreads the light striking it. Screen gain is
less than 1 but audience viewing angles are increased.
ö
An adjustment that affects the display of an image. Such display settings include
contrast, brightness, tint, blanking, focus, offsets, etc.
ö
A very rapid variation in image brightness caused by a frame rate that is too
slow. (See Interlace.)
ö
The frequency at which complete images are generated. For non-interlaced
signals, the frame rate is identical to the vertical frequency. For interlaced
signals, the frame rate is one half of vertical frequency.
ö
The intensity of visible light per square foot.
ö
The luminance (brightness) which results from one foot-candle of illumination
falling on a perfectly diffuse surface.
