Glossary
 
Analog audio
 
An electrical signal that directly represents sound. Com-
pare this to digital audio which can be an electrical sig-
nal, but is an indirect representation of sound. See also 
“Digital audio.”
 
Aspect ratio
 
The width of a TV screen relative to its height. Conven-
tional TVs are 4:3 (in other words, the screen is almost 
square); widescreen models are 16:9 (the screen is 
almost twice as wide as it is high).
 
Digital audio
 
An indirect representation of sound by numbers. During 
recording, the sound is measured at discrete intervals 
(44,100 times a second for CD audio) by an analog-to-
digital converter, generating a stream of numbers.
On playback, a digital-to-analog converter generates an 
analog signal based on these numbers. See also “Sam-
pling frequency” and “Analog audio.”
 
DivX

DivX is a media technology created by DivX, 
Inc. DivX media files contain compressed video. DivX

Dynamic range

lost in noise).
Dolby Digital and DTS soundtracks are capable of a very 
wide dynamic range, delivering dramatic cinema-like 
effects.

A tag added to the end of a filename to indicate the type 
of file. For example, “.mp3” indicates an MP3 file.

encrypted video.
