Section 1: Introduction
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. Refer to 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 called 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 optional device that converts NTSC 3.58, NTSC 4.4, PAL, PAL-N, PAL-M or SECAM to RGB video. Not
applicable to CP2000 XB.
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.
