Complex terms used in this book, or terms not explained in the body of the text, will be briefly explained here. For further explanation, please consult commercially available reference texts.

5BNC

A type of connector used to input analog video

 

signals.

 

 

Aspect ratio

The ratio between an image's length and its height.

 

Images which have an aspect ratio of 16:9 are called

 

Widescreen. The aspect ratio for standard images is

 

4:3.

 

 

Color

The temperature of an object which is emitting light.

Temperature

When the colour temperature is high, colours tend to

 

take on a bluish tinge; when the colour temperature

 

is low, colours tend to take on a reddish tinge.

 

 

Component

A type of video signal which has the video

Video

brightness and colour signal information 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

The standard home video signal (NTSC, PAL,

 

SECAM) which has the video brightness and colour

 

signal information mixed together. Composite video

 

consists of the carrier signal Y (luminance signal)

 

and the chroma (colour) signal, combined within the

 

colour bar 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, or appear softer.

 

Adjusting this particular property of an image is

 

called "contrast adjustment".

Cool-down

The process used to cool down 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. Do

 

not unplug the projector power cable whilst it is

 

cooling down. If cool-down is interrupted, heat from

 

the lamp gets trapped inside the projector, potentially

 

shortening the life of the lamp and causing projector

 

failure.

 

 

 

Dolby

An audio format developed by Dolby Laboratories.

digital

Normal stereo is a 2-channel format which uses two

 

speakers, whereas Dolby Digital is a 6-channel (5.1-

 

channel) system which adds 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 scanningg, i=Interlaced scanningg)

 

• Screen aspect ratio of 16:9

 

Dolby digitalgl audio reception and playback (or

 

output)

 

 

 

Interlaced

Each screen is divided into fine horizontal lines

scanning

which are displayed in sequence starting from left to

 

right and then from top to bottom. This method of

 

image scanning, whereby even numbered lines and

 

odd numbered lines are displayed alternately, is

 

called Interlaced scanning.

 

 

 

Progressive

A method of image scanning whereby the image data

scanning

from a single image is scanned sequentially from top

 

to bottom to create a single image.
