The signal representing the color information (hue and saturation) when the image is
represented as separate chrominance and
luminance . Same as “chroma”.
The fraction of a motion picture frame image that is intended to be viewed by the
audience. The clean aperture is subjectively free of edge artifacts and lies within the
screen area framed by curtains in a cinema. Aspect ratio is often referenced to the
clean aperture.
The range of colors allowed in a specific system, as defined within a triangular area
located on the CIE color locus diagram whose corners are the three primaries of the
system. Same as color space.
A change in the tint of a white field across an image.
The coloration (reddish, white, bluish, greenish, etc.) of white in an image, measured
using the Kelvin (degrees K) temperature scale. Higher temperatures output more
light.
See YCbCr or YPbPr.
The output of video tape players and some computers, characterized by
synchronization, luminance and color signals combined on one output cable.
The degree of difference between the lightest and darkest areas of the image.
The alignment of the red, green, and blue light elements of a projected image so that
they appear as a single element. In this projector, convergence can be adjusted by
Christie service personnel only.
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
°
. Curved screens are not recommended for use with this projector.
Digital Cinema Distribution Master. A file or collection of files formatted for
exhibition and comprised of all the components of the
title . A reference size of about
200 GB per title is likely.
The Display Data Channel VESA standard enables communication between PCs and
monitors, and is based on E-EDID protocol.
Digital Micromirror Devices  used in this projector for processing red, green, and
blue color data.
Dynamic Host Configuration Protocol is a commonly used client-server networking
protocol. It enables a DHCP server to allocate valid IP addresses to projectors
detected on a local network.
NOTE: Not supported in this projector.
Digital Source Master. A title’s native source files in acquisition format, edited to
create the distribution master and for reformatting for NTSC, HDTV, DVD, etc., and
potentially archived.
The Digital Visual Interface standard signal supplies digital RGB, sync, I
2
C, and
clock information to the single-link DVI-1 or DVI-2 ports on the projection head.
