Digital Audio Signals

The DIRECTV

®

HD 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 sending 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

®

audio, formally known as Audio Coding 3rd Generation is a

coding technique that can provide up to five independent, 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.
