Dolby Digital
Dolby Digital is the standard audio format for DVDs and for digital television broadcasting in the United States.
A Dolby Digital 2.0 soundtrack is a digital 2- channel recording of a matrix encoded Dolby Surround soundtrack. To play a Dolby Digi- tal 2.0 recording, use Dolby Pro Logic II de- coding as previously described.
A Dolby Digital 5.1 soundtrack has six dis- crete channels: front left, front center, front right, surround left, surround right, and a Low Fre- quency Effects (LFE) channel containing bass signals intended for a subwoofer.
Decoding of Dolby Digital 5.1 sound- tracks is automatic.
NOTE: Many DVDs have a Dolby Digital 2.0 matrix soundtrack as the default. The Dolby Digital 5.1 soundtrack may have to be se- lected as an option from the setup menus at the beginning of the DVD.
DTS 5.1
DTS® (Digital Theater Systems) is an alterna- tive digital format competing with Dolby Digital in both movie theaters and home theater markets. The basic functions of the DTS sys- tem are similar to those of Dolby Digital (for example, 5.1 discrete channels), however the technical details of the compression and de- coding processes differ somewhat.
Like Dolby Digital, DTS can only be used on a digital recording and, therefore, is only available for home use on LaserDiscs, DVDs, or other digital formats.
Detection and proper decoding of DTS 5.1 signals is automatic.
NOTE: DVDs with a DTS soundtrack almost always have it configured as an option to the standard matrix Dolby Surround format. To use DTS, you may have to go to the setup menus at the beginning of the DVD and se- lect “DTS 5.1” instead of “Dolby Surround” or “Dolby Digital 5.1”.
