Glossary
Following is an explanation of some of the terms used in this guide which may be unfamiliar or which were not explained in the manual itself. Further information can be obtained by referring to other commercially- available publications.
Component | Video signals which have the video brightness signals and color signals separated, in order to provide | |
video | better image quality. | |
| In | |
| (luminance signal), and Pb and Pr (color difference signals). | |
|
| |
Composite | Video signals which have the video brightness signals and color signals mixed together. The type of | |
video | signals commonly used by household video equipment (NTSC , PAL and SECAM formats). | |
| Video signals which consist of a carrier signal Y (luminance signal) within the color bar signal, and a | |
| chroma or color signal (CbCr). | |
|
| |
| This is the process by which the projector's lamp is cooled down after it has become hot through use. It | |
| is carried out automatically when the [Power] button on either the remote control or the projector's | |
| control panel has been pressed to the projector off. Do not disconnect the power cord while | |
| is in progress, otherwise the | |
| allowed to finish normally, the projector's lamp and internal components will remain at high | |
| temperatures, and this may shorten the useful life of the lamp or cause problems with the operation of | |
| the projector. The | |
| the external air temperature. | |

| |
DCDi | An abbreviation for Directional Correlational Deinterlacing. Refers to a | |
function | function developed by Faroudja. It incorporates the latest in edge cutting technology to smooth the | |
| jaggedness from the edges of images that have been converted from interlaced to progressive video, in | |
| order to provide more natural images. | |
|
| |
HDMI | An abbreviation for High Definition Multimedia Interface, and refers to a standard for digital | |
| transmission of | |
| HDMI is a standard that is targeted towards household digital equipment and computers that allows | |
| digital signals to be transmitted in their original high quality without compression, and it also includes | |
| a digital signal encryption function. | |
|
| |
HDTV | An abbreviation for | |
| following conditions. | |
| • | Vertical resolution of 720p or 1080i or greater |
|
| (p = progressive, i = interlaced ) |
| • | Screen aspect of 16:9 |
| • | Dolby Digital audio reception and playback (or output) |
|
| |
Interlace | A method of image scanning whereby the signal bandwidth used is approximately half that required for | |
| sequential scanning when images with the same still picture resolution are broadcast. | |
|
| |
NTSC | An abbreviation for National Television Standards Committee, and a format for | |
| color television broadcasts. This format is used in North America, Japan, and Central and South | |
| America. | |
|
| |
PAL | An abbreviation for Phase Alternation by Line, and a format for | |
| television broadcasts. This format is used in Western European countries except France, and also in | |
| Asian countries such as China and in Africa. | |
|
| |
Refresh | The | |
rate | time. Because of this, the image must be scanned many times per second in order to refresh the light | |
| emitting element. The number of refresh operations per second is called the "refresh rate", and is | |
| expressed in hertz (Hz). | |
|
| |
A video signal which has the luminance component and color component separated in order to provide | ||
| better image quality. | |
| It refers to images which consist of two independent signals: Y (luminance signal), and C (color | |
| signal). | |
|
| |
SDTV | An abbreviation for Standard Definition Television. It refers to standard television systems which do | |
| not satisfy the conditions for HDTV . | |
|
| |
SECAM | An abbreviation for Sequential Couleur A Memoire, and a format for | |
| television broadcasts. This format is used in France, Eastern Europe and the former Soviet Union, the | |
| Middle East and Africa. | |
|
| |
sRGB | An international standard for color intervals that was formulated so that colors which are reproduced | |
| by video equipment can be handled easily by computer operating systems (OS) and the Internet. | |
|
| |
SVGA | A type of image signal with a resolution of 800 (horizontal) × 600 (vertical) dots which is used by IBM | |
| PC/ | |
