High-definition Television (1035, 1080 and 1125 lines interlace, and 720 and 1080
line progressive formats with a 16:9 (i.e. 1.77) aspect ratio.
A display of help information regarding the current task or presentation. Not
available in CP2000.
The frequency at which scan lines are generated, which varies amongst sources. Also
called horizontal scan rate or line rate.
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 to one side of the lens center without degrading the
image quality.
A circular area of a screen where the image appears brighter than elsewhere on the
screen. A hot spot appears along the line of sight and "moves" with the line of sight.
High gain screens and rear screens designed for slide or movie projection usually
have a hot spot.

motorized lens mount to automatically return to lens settings previously defined for a
particular channel. Not available in cinema projectors such as CP2000.

representing 1) its switcher/projector location and 2) its slot in the switcher/projector.
Signal sent from a source device to the projector.
A device, such as the Serial Digital Input Module, that accepts an input signal for
display by the projector. Interfaces are not used with the CP2000.
A method used by video tape players and some computers to double the vertical
resolution without increasing the horizontal line rate. If the resulting frame/field rate
is too low, the image may flicker depending on the image content.
A distortion of the image which occurs when the top and bottom borders of the image
are unequal in length. Side borders both slant in or out, producing a "keyhole" shaped
image. It is caused when the lens surface is not parallel to the screen.


A Christie software feature where samples of output light from a projector guide the
precise position of the lamp along 3 axes—vertical, horizontal and distance to lens—
so that lamp performance and output is maximized.
A safety control system integrated into the HVAC, fire alarm, and other
infrastructure components of the theatre as well as the presentation system.
Comment: In the event of a fire, for example, the life safety system may turn on the
auditorium lighting to full intensity, cancel the presentation audio and replace it with
a PA microphone or pre-recorded announcement, turn the lamp off, flash warning
lights, and so forth. Every jurisdiction may have different statutory requirements for
life safety systems.
The reproduction of the horizontal and vertical size of characters and/or shapes over
