Following is an explanation of some of the terms used in this guide which may be unfamiliar or which were not explained in the text of this guide itself.
Further information can be obtained by referring to other commercially-available publications.
3-2 pull-down
function
This function directly converts image sources that have been recorded in the same 24-frame format used for movies into 60-frame progressive signals.
This allows data such as DVD software that has been recorded in 24-frame format to be played back on large screens with more natural and accurate
reproduction, without any loss of image quality from the original movie.
Aspect ratioThe ratio between an image's length and its height. HDTV images have an aspect ratio of 16:9 and appear elongated. The aspect ratio for standard
images is 4:3.
Authentication
server
This is a server that centrally manages user authentication. By using an authentication server, management of user information and user authentication
tasks can be centralised. In addition, many authentication servers use high-level authentication methods and so they also tend to be highly secure.
CCXAbbreviation for Cisco Compatible Extensions. This is a security technology for wireless LANs developed by Cisco Systems, Inc. It uses RADIUS
serversg for authentication. Several authentication methods are available for CCX, and this projector uses LEAPg authentication.
ChannelCommunication speeds will drop if there are too many devices performing wireless communication using the same frequency. In this case, it is
possible to avoid interference from other wireless LANs by setting a wireless channel for each wireless LAN network.
Colour
temperature
A characteristic that determines the colour tones of images. When the colour temperature is high, colour tones appear bluish, and when the colour
temperature is low, images appear reddish.
Component
video
Video signals which have the video brightness signals and colour signals separated, in order to provide better image quality.
In high-definition TV (HDTV), it refers to images which consist of three independent signals: Y (luminance signal), and Pb and Pr (colour difference
signals).
Composite videoVideo signals which have the video brightness signals and colour signals mixed together. The type of signals commonly used by household video
equipment (NTSC, PAL and SECAM formats).
The signals consist of the carrier signal Y (luminance signal) and the chroma (colour) signal which are contained in the colour bar signal.
ContrastThe relative brightness of the light and dark areas of an image can be increased or decreased in order to make text and graphics stand out more clearly,
or to make them appear softer. Adjusting this particular property of an image is called "contrast adjustment".
Cool-downUse this procedure to cool a projector lamp that is hot from use. Cool- down happens automatically when the [Power] button is pressed on the
projector or on the remote control to turn the projector off.
DFPAbbreviation for Digital Flat Panel. Refers to a standard method for digital transmission of video signals.
DHCPAbbreviation of Dynamic Host Configuration Protocol. This protocol automatically assigns an IP address to a computer connected to a network.
Dolby DigitalA sound format developed by Dolby Laboratories. Normal stereo is a 2-channel format which uses two speakers. Dolby Digital is a 6-channel (5.1-
channel) system which adds to this a centre speaker, two rear speakers and a sub-woofer.
DPOFAbbreviation of Digital Print Order Format, which is a format used to record infomation concerning the printing of photographs taken with a digital
camera (which images to print, how many copies, etc.) to recordable media, such as a memory card.
DVIAbbreviation for Digital Visual Interface. Refers to a standard method for digital transmission of video signals.
DVI is a standard which has also been applied to digital household electronic equipment other than computers. It allows images to be transmitted at
higher resolutions than for DFP, and also includes a digital signal encoding function.
