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.”

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.
