A-2 RPMSP & CSP70-D100U User’s Manual
A number that uniquely identifies a specific channel retained in projector memory.
The projector can retain up to 50 channels.
A menu item that indicates whether an option is currently in effect (checked) or not
(unchecked).
The signal representing the color information (hue and saturation) when the image is
represented as separate chrominance and luminance. Same as “chroma”.
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 defined
in the system. Also known 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 elements of a projected image so that they
appear as a single element.
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.
The Display Data Channel VESA standard enables communication between PCs and
monitors, and is based on E-EDID protocol.
A “direct digital interface” signal can be supplied to the projector via an optional
digital input module installed in
INPUT 5. For example, you can input an SMPTE-
259M signal using a Serial Digital Input Module or input an SMPTE-272M signal
from a Digital HDTV Serial Input Module.
Digital Micromirror Devices
used in this projector for processing red, green, and
blue color data.
Located at
INPUT 3 and INPUT 4, this device converts NTSC 3.58, NTSC 4.4, PAL,
PAL-N, PAL-M, or SECAM to RGB video.
The sharpness of a display from a video source.
A type of rear-projection screen which spreads the light striking it. Screen gain is less
than 1 but audience viewing angles are increased.
An adjustment that affects the display of an image. Such display settings include
contrast, brightness, tint, blanking, size, offsets, and others.
