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 text of this guide itself. Further information can be obtained by referring to other commercially- available publications.

Aspect ratio

The 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.

 

 

Colour

The temperature of an object which is emitting light. If the colour

temperature

temperature is high, the colours tend to take on a bluish tinge. If the

 

colour temperature is lower, the colours tend to take on a reddish tinge.

 

 

Component

Video signals which have the video brightness signals and colour

video

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

Video signals which have the video brightness signals and colour

video

signals mixed together. The type of signals commonly used by

 

household video equipment (NTSC, PAL and SECAM formats).

 

The carrier signal Y (luminance signal) and chroma (colour) signal

 

which are contained in the colour bar are overlapped to form a single

 

signal.

 

 

Contrast

The 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-down

The cooling process for the projector's lamp unit continues even after

 

the [Power] button on the projector's control panel or the remote control

 

has been pressed to turn off the lamp. After the lamp turns off, the

 

cooling fan continues operating, but all button operations are disabled.

 

The length of time that this is happening is called the "cool-down

 

period". The cool-down period lasts for about 20 seconds. The actual

 

time will vary depending on the external air temperature.

 

 

Dolby Digital

A 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.

 

 

HDTV

An abbreviation for High-Definition Television. It refers to high-

 

definition systems which satisfy the following conditions.

 

• Vertical resolution of 750p or 1125i or greater (p = progressive

 

scanning , i = interlaced scanning )

 

• Screen aspect ratio of 16:9

 

• Dolby Digital audio reception and playback (or output)
