GLOSSARY
Unicode 
The Unicode method of encoding produces a very large character set typically
required for ASCII messaging in non-Western languages such as Chinese, Russian,
etc. In unicode, every number (code) is unique to a single character. A limited
number of TPC functions can be executed remotely via unicode or non-unicode
(default) messaging—this is auto-detected. See also non-unicode.
Variable Scan 
The ability of a projector to synchronize to inputs with frequencies within a specified
range.
Vertical Frequency 
The frequency at which images are generated. Vertical frequencies vary amongst
sources. Also known as vertical scan rate.
Vertical Offset 
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 above or below the lens center without degrading
the image quality. All CP2000 lenses have the same vertical offset range.
VESA 
The Video Electronic Standards Association establishes standards of communication
between electronic components to help ensure universal compatibility.
Video 
The signal that is used by display devices (such as projectors) to generate an image.
This term also refers to the output of video tape/disk players and computers.
Video Decoder 
An interface module that converts NTSC 3.58, NTSC 4.4, PAL, PAL-N, PAL-M or
SECAM to RGB video. Not applicable to CP2000.
Video Standard 
A specific type of video signal, such as NTSC, PAL, SECAM.
Viewing Angle 
Screens do not reflect equally in all directions. Instead, most light is reflected in a
conical volume centered around the "line of best viewing". Maximum brightness is
perceived if you are within the viewing cone defined by the horizontal and vertical
viewing angles.
Watermark 
Data embedded in essence that serve different purposes and that are either
imperceptible or obvious, robust or fragile. Their usual purpose is for legal support of
copyright, and they may also be components of copy control schemes.
White Balance 
The color temperature of white used by the projector.
White Field 
The area of an image that is white only. For example, a full white field is an image
that is white everywhere. A 10% white field is a white area (usually rectangular) that
occupies 10% of the image; the remaining 90% is black.
YCbCr 
A high-end digital component video signal.
YPbPr 
A high-end analog component video signal. Sometimes called YUV, Component, or
Y, R-Y, B-Y, the YPbPr signal by-passes video decoding.
YUV 
See YPbPr.
Zoom 
The adjustment of image size by means of a zoom lens.
