This appendix defines terms used in this manual as they apply to this projector.
'
The time, inside one horizontal scan line, during which video is generated.
'
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.
The video output of most computers and videotape machines. Analog video can
'
generate a large number of colors.
'
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.
The American National Standards Institute is the organization that denotes the
'
measurement standard for lamp brightness.
'
An Ethernet communication protocol that was developed by Artistic Licence. It is
used for controlling lighting/staging equipment from a lighting console or PC
application.
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.
The ability of the projector to automatically recognize and synchronize to the
'
horizontal and vertical scan frequencies of an input signal for proper display.
'
The frequency range of the projector's video amplifier.
'
The speed (bits-per-second) at which serial communications travel from their origin.
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.
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.
'
Unit of measure for measuring intensity of light.
A collection of measurements stored by the projector for a given input source,
'
including frequencies, pulse width, polarity, syncs, channel number and location,
