    							Glossary47
    Appendix: Glossary
    ANSI LUMENS —A standard for measuring the brightness. It is calculated by 
    dividing a square meter image into nine equal rectangles, measuring the lux (or 
    brightness) reading at the center of each rectangle, and averaging these nine 
    points.
    A
    SPECT RATIO —The most popular aspect ratio is 4:3 (4 by 3). Early television and 
    computer video formats are in a 4:3 aspect ratio, which means that the width of 
    the image is 4/3 times the height.
    Brightness— The amount of light emitting from a display or projection display or 
    projection device. The brightness of projector is measured by ANSI lumens.
    Color Temperature— The color appearance of white light.  Low color 
    temperature implies warmer (more yellow/red) light while high color temperature 
    implies a colder (more blue) light.  The standard unit for color temperature is 
    Kelvin (K).
    Component Video—A method of delivering quality video in a format that 
    consists of the luminance signal and two separate chrominance signals and are 
    defined as YPbPr for analog component and YCbCr for digital component. 
    Component video is available on DVD players.
    Composite Video — A video signal that combines the luma (brightness), chroma 
    (color), burst (color reference), and sync (horizontal and vertical synchronizing 
    signals) into a signal waveform carried on a single wire pair. There are three kind of 
    formats, namely, NTSC, PAL and SECAM.
    Compressed Resolution— If the input images are of higher resolution than the 
    native resolution of the projector, the resulting image will be scaled to fit the 
    native resolution of the projector.  The nature of compression in a digital device 
    means that some image content is lost.
    Contrast Ratio— Range of light and dark values in a picture, or the ratio between 
    their maximum and minimum values. There are two methods used by the 
    projection industry to measure the ratio:
    1Full  On/Off — measures the ratio of the light output of an all white image (full 
    on) and the light output of an all black (full off) image. 
    2ANSI — measures a pattern of 16 alternating black and white rectangles. The 
    average light output from the white rectangles is divided by the average light 
    output of the black rectangles to determine the 
    ANSI contrast ratio. 
    Full On/Off contrast is always a larger number than ANSI contrast for the same 
    projector. 
    						
    							48Glossary
    dB— decibel—A unit used to express relative difference in power or intensity, 
    usually between two acoustic or electric signals, equal to ten times the common 
    logarithm of the ratio of the two levels. 
    Diagonal Screen— A method of measuring the size of a screen or a projected 
    image. It measures from one corner to the opposite corner. A 9FT high, 12FT 
    wide, screen has a diagonal of 15FT. This document assumes that the diagonal 
    dimensions are for the traditional 4:3 ratio of a computer image as per the example 
    above. 
    DLP
    ®— Digital Light Processing™—Reflective display technology developed by 
    Texas Instruments, using small manipulated mirrors. Light passes through a color 
    filter is sent to the DLP mirrors which arrange the RGB colors into a picture 
    projected onto screen, also known as DMD.
    DMD— digital Micro- Mirror Device— Each DMD consists of thousands of 
    tilting, microscopic aluminum alloy mirrors mounted on a hidden yoke.  
    DVI-D— Digital Visual Interface-Digital connector.
    Focal Length— The distance from the surface of a lens to its focal point.
    Frequency— It is the rate of repetition in cycles per seconds of electrical signals. 
    Measured in Hz (Hertz). 
    Hz (Hertz)— Unit of frequency.
    Keystone Correction— Device that will correct an image of the distortion 
    (usually a wide-top narrow-bottom effect) of a projected image caused by 
    improper projector to screen angle.
    Maximum Distance— The distance from a screen the projector can be to cast an 
    image that is usable (bright enough) in a fully darkened room. 
    Maximum Image Size— The largest image a projector can throw in a darkened 
    room. This is usually limited by focal range of the optics. 
    Minimum Distance— The closest position that a projector can focus an image 
    onto a screen.
    NTSC— National Television Standards Committee.  North American standard for 
    video and broadcasting, with a video format of 525 lines at 30 frames per second.
    PAL— Phase Alternating Line.  A European broadcast standard for video and 
    broadcasting, with a video format of 625 lines at 25 frames per second.
    Reverse Image— Feature that allows you to flip the image horizontally. When 
    used in a normal forward projection environment text, graphics, etc, are 
    backwards. Reverse image is used for rear projection.
    RGB— Red, Green, Blue— typically used to describe a monitor that requires 
    separate signals for each of the three colors. 
    						
    							Glossary49
    S-Video—A video transmission standard that uses a 4-pin mini-DIN connector to 
    send video information on two signal wires called luminance (brightness, Y) and 
    chrominance (color, C). S-Video is also referred to as Y/C.
    SECAM— A French and international broadcast standard for video and 
    broadcasting, closely related to PAL but with a different method of sending color 
    information.
    SVGA— Super Video Graphics Array— 800 x 600 pixels count.
    SXGA— Super Extended Graphics Array,—1280 x 1024 pixels count.
    UXGA— Ultra Extended Graphics Array—1600 x 1200 pixels count.
    VGA— Video Graphics Array—640 x 480 pixels count.
    XGA— Extended Video Graphics Array— 1024 x 768 pixels count.
    Zoom Lens— Lens with a variable focal length that allows operator to move the 
    view in or out making the image smaller or larger. 
    Zoom Lens Ratio— Is the ratio between the smallest and largest image a lens can 
    projector from a fixed distance. For example, a 1.4:1 zoom lens ratio means that a 
    10 foot image without zoom would be a 14 foot image with full zoom.
