Digital Audio Signals

The DIRECTV

High-Definition Receiver will be the focal center of your home entertainment system

comprising a variety of components, such as TV, DVD, VCR, etc. and external audio systems. Since

digital programs being broadcast contain digital-quality audio, you can create a home theater by send-

ing audio signals from the DIRECTV HD Receiver to your audio system externally. HD digital signals

use the Dolby Digital audio encoding system - the same digital sound used in many movie theaters, on

DVDs, and in many home theater systems.

When you tune to a channel, the DIRECTV HD Receiver can send signals either to a Dolby Digital

decoder/receiver or to a PCM (normal digital) decoder. (* Refer to Section 3.7 Connection for Audio

for making the required external connections to your system.)

Dolby Digital, formally known as AC-3 for Audio Coding 3rd Generation or

“5.1” channel audio, is a coding technique that can provide up to five inde-

pendent, full frequency response audio channels (three in left, center, and

right, two in rear left and right, and one low frequency effect for a sound

you can feel).
