Dolby Digital
Dolby Digital is a digital audio format which mainly provides
high-quality multi-channel audio for sound tracks of movies. It
provides us up to independent 6 channels compatible with the
6 speaker configuration: Left main, right main, center, left
surround, right surround and subwoofer. It stores a large
volume of digital sound signals (as data) into a laserdisc, DVD,
etc. with a high level data-compression technology.
DTS
DTS (Digital Theater Systems) is also a multi-channel digital
audio format. It provides us up to 6 channels. DTS encodes
high-quality, 20-bit audio onto laserdiscs, compact discs and
DVDs with less data-compression.
Linear PCM
A basic digital audio format used in CDs. It is based on Pulse
Code Modulation (PCM), an analog-to-digital conversion
technology. No compression is applied to the data.

the MPEG (Moving Picture Expert Group) 1 format, a data
compression technology.

A digital audio format mainly used in Europe, Australia, etc. It
provides us high-quality multi-channel audio up to 8 channels
in the same way as Dolby Digital and DTS. It is based on the
MPEG 2 format, a data compression technology improved
more than MPEG 1.
