Technical overview

Dolby® Digital 5.1

Just as the ATSC has specified 1080i or 720p as the video formats required for HDTV, they have also specified a recommended audio format: Dolby Digital 5.1.

Dolby Digital 5.1 provides 5 discrete channels of digital audio information for use by A/V receivers capable of decoding the 5.1 channel signal.

The audio signals are broken into left-front, center, right-front, left-rear, right-rear and a low-frequency effects channel (designed for subwoofers).

The result when connected to a compatible Dolby Digital 5.1 channel A/V receiver and speaker setup is a home theater experience that provides much of the dynamic range, 360-degree imaging, and sonic excitement of a real theater.

Not all Digital TV programming is broadcast using Dolby Digital 5.1.

For DIRECTV® programming, you can see which programs are broadcast using this high-quality audio standard by checking the Info Banners and Program Guides for the

Dolby Digital icon ( ).

To take full advantage of the Dolby Digital 5.1 capabilities of the DIRECTV® HD Receiver, you will need a Dolby Digital 5.1 compatible A/V receiver connected to the DIRECTV® HD Receiver through the Dolby Digital Optical jack or the Dolby Digital Coaxial jack.
