[. . . ] 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. Backlit (Backlight)--Refers to a remote control, or a projector control panel, that has buttons and controls that are illuminated. Bandwidth-- The number of cycles per second (Hertz) expressing the difference between the lower and upper limiting frequencies of a frequency band; also, the width of a band of frequencies. 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-- A method of measuring the whiteness of a light source. Metal halide lamps have a higher temperature compared to halogen or incandescent lights. Component Video--A method of delivering quality video in a format that contains all the components of the original image. These components are referred to as luma and chroma and are defined as Y'Pb'Pr' for analog component and Y'Cb'Cr' for digital component. Component video is available on DVD players and projectors. Composite Video -- The combined picture signal, including vertical and horizontal blanking and synchronizing signals. Compression-- A function that deletes resolution lines from the image to fit in the display area. Compressed SVGA-- To project an 800x600 image to a VGA projector, the original 800x600 signal must be compressed down. The data displays all the information with only two thirds of the pixels (307, 000 vs 480, 000). The resulting image is SVGA page size but sacrifices some of the image quality. If you are using an SVGA computers, connecting VGA to a VGA projector. Compressed SXGA-- Found on XGA projectors, compressed SXGA handling allows these projectors to handle up to 1280x1024 SXGA resolution. Compressed XGA-- Found on SVGA projectors, compressed XGA handling allows these projectors to handle 1024x768 XGA resolution. Glossary 63 www. dell. com | support. dell. com 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: 1 Full 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. 2 ANSI -- 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. [. . . ] · · · : DLP : 3400MP/DELL : Dell Inc.
