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 files can
also include advanced media features like menus, subti-
tles, and alternate audio tracks.
Dolby Digital
Using a maximum of 5.1 channels of audio, this high
quality surround system is used in many of the finer
movie theaters around the world.
The display shows which channels are active, for exam-
ple showing 3/2.1. The 3 being the two front channels
and the center channel; the 2 being the surround chan-
nels, and the .1 being the LFE channel.
Down Mix
Down mixing reduces the number of surround-sound
channels and mixes the multi-channel audio that is used
in Dolby Digital and DTS so that the audio matches the
number of speakers and other elements of the output
environment.
DRM
DRM (digital rights management) is a type of server
software developed to enable secure distribution of paid
content over the web, recently incorporated by WMA
(Windows Media Audio).
DTS
DTS stands for Digital Theater Systems. DTS is a sur-
round system different from Dolby Digital that has
become a popular surround sound format for movies.
