GLOSSARY

4:3 – See “Aspect ratio.”

16:9 – See “Aspect ratio.”

Analog audio – The sounds that we hear with our

ears, unlike digital audio that is encoded as bits of

information.

Aspect ratio – An expression for the width of the

picture relative to the height. For example, if the aspect

ratio is 4:3 (considered a normal screen), the shape of

that picture is 4 units wide by 3 units high. The

standard TV aspect ratios are 4:3 and 16:9 (called

widescreen).

CD – The abbreviation for a compact disc that stores

digitally encoded music that is read by the laser beam

in a compact disc player. This provides high-quality

playback.

Chapter – A main division of contents in a DVD title.

Coaxial cable – Can carry digital audio signals

between a source device and the 3•2•1

system.

Component video – Also called YPbPr for its three-

part video signals that include luminance and two color

signals. Component video requires the use of a

Component cable. This provides considerably better

resolution than is possible from either Composite or

S-Video signals.

Composite video – The simplest of video signals,

which combines black and white with color information.

Its low- resolution signal is compatible with the

broadest range of televisions and other video

components and requires a simple RCA video cable.
