video server products, proposed for standardization by SMPTE and as a primary

component of MXF. Initially implemented on Fibre Channel using FTP with TCP/IP

but extensible to XTP or other protocols. Previously called GXF: General Exchange

Format.

High-bandwidth Digital Content Protection protocol of keys and encryption helps

prevent DVI source material from being copied.

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.

The Intelligent Lens System

™ describes the ability of Christie projectors having a

motorized lens mount to automatically return to lens settings previously defined for a

particular channel. Not available in cinema projectors such as CP2000.

A physical connection route for a source signal, described by a 2-digit number

representing 1) its switcher/projector location and 2) its slot in the switcher/projector.

Signal sent from a source device to the projector.

An optional device such as a 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:
