ANSI
Abbreviations of the American National Standards Institute
ANSI Lumen
Unit of brightness as defined by the American National Standards Institute. This value is determined as follows: project
light onto a 40-inch screen, divide the screen into 9 rectangles and measure the average brightness of each of the
rectangles. Since the brightness at the center is generally different from that of the edges, ANSI Lumen provides a more
precise measure of the projector brightness than LUX.
AV Receiver
An AV Receiver provides a number of input and output interfaces for audio and video so as to enable the user to
connect and use various input and output devices.
Backwards Compatible
Backwards compatibility for previous computer models. The SVGA (800*600) projector provides backwards
compatibility for SVGA and VGA (640*480) computers.
Compression Mode
A mode that displays video in a zoomed out format.
Contrast Ratio
The ratio of the brightest and dimmest points that can be displayed on the screen.
Convergence
The alignment of the Red, Green and Blue video signals on the projected picture on the screen.
Display Size
The Display Size is determined by the diagonal length of the LCD panel.
DVD (Digital Versatile Disc)
Digital media developed to provide the advantages of CD and LD. DVD provides high quality video and audio.
DLP (Digital Light Processing)
DLP is a digital display technology using a DMD panel developed by TI (Texas Instruments) of the United States.
DLP HD2, DC2, DC3
This is a grade of DMD panel.
DMD (Digital Micromirror Device)
A DMD panel is an implementation of DLP technology. It consists of microscopic mirrors where each mirror represents
a pixel.
EGA
Enhanced Graphics Array. EGA provides enhanced graphics quality in IBM PC, XT and AT as a CGA card. (640x350
pixels for all modes)
Hz (kHz, MHz)
Hertz (Kilohertz, Megahertz). Frequency per second. (Kilo: 1,000, Mega: 1 million) Hz is used to represent the frequency
of electric signals.
NTSC
National Television Standards Committee. A TV and video signal transmission standard developed in North America in
1953. 525lines / 60 Hz
PAL
Phase Alternate Line. A method to transmit and receive color line by line. PAL is widely used in Western European
countries. 625lines / 50 Hz
SECAM
Sequential Couleur Avec Memorie. A method developed in France to transmit and receive the color TV broadcasting.
SECAM is mainly used in France and Eastern European countries. 625 lines / 50 Hz
Super VGA (SVGA)
SVGA provides a graphics resolution of 800x600 pixels. This standard includes a vertical frequency version.
VGA
Video Graphics Array. Standard output interface for IBM PS/ 2. An analog graphics card developed by IBM that supports
720x400 pixels resolution in text mode and 640x480 pixels for graphics mode. (Other graphics cards process digital
data.)
Video
The picture projection capability of a PC with a VCR, Laser disk or CD-ROM drive.
