DirecTV H10 manual Recommended audio format for Hdtv is Dolby Digital

Introduction

12Defining High-Definition

Dolby® Digital 5.1

The recommended audio format for HDTV is Dolby® Digital 5.1.

This format offers five discrete channels of mid- and high-range digital audio, plus one channel of low-frequency (subwoofer) audio for use by A/V receivers capable of decoding the

5.1channel signal. The audio signals are broken into left-front, center, right-front, left-rear, right-rear and low-frequency. The result, when your DIRECTV HD Receiver is connected to a compatible Dolby Digital 5.1 channel A/V receiver and speaker setup, is an experience that gives you much of the dynamic range, 360-degree imaging and sonic excitement of a real theater.

Not all TV programs are broadcast using Dolby Digital 5.1. For DIRECTV programming, shows broadcast using this high-quality audio standard are indicated by the words Dolby Digital in the Channel Banner (see page 41) and Program Guide (see page 43).

If you are using the Digital Audio Output (Optical, Coax or HDMI) from your DIRECTV HD Receiver to a digital audio (A/V) receiver or TV, you can set your preference by going here:

1)While in Live TV press MENU.

2)From the Quick Menu, SELECT Settings.

3)Scroll down to Setup and press SELECT.

4)Scroll down to Audio, and press SELECT.

5)Scroll up to the tabs and scroll over to Digital Audio and press SELECT.

6)Scroll to Dolby Digital and SELECT On or Off. If you set this to “Off”, then the audio on the Digital Outputs will always be in PCM (L/R Stereo).

7)If you set the Dolby Digital to “On”, then you should also setup the Digital Output.

8)Scroll to Digital Output and presse SELECT:

—Dolby Digital: if you want programs to be heard in Dolby Digital when available

—PCM if you want programs (with and without Dolby Digital) to be heard in L/R stereo only.
