DHCP - Dynamic Host Configuration Protocol - A network protocol that enables a server to automatically assign a TCP/IP address to a device. DLP® - Digital Light Processing™ - Reflective display technology developed by Texas Instruments, using small manipulated mirrors. Light passing 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. 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). HDCP - High-Bandwidth Digital-Content Protection - A specification developed by Intel™ Corporation to protect digital entertainment across digital interface, such as DVI, HDMI. HDMI - High-Definition Multimedia Interface - HDMI carries both uncompressed high definition video along with digital audio and device control data in a single connector. Hz (Hertz) - Unit of frequency. Keystone Correction - Device that will correct an image of the distortion (usually a wide-top narrowbottom 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. 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. 56
