CHAPTER 1
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
you will need a Dolby Digital 5.1 compatible A/V receiver connected to the DIRECTV
Receiver through the Dolby Digital Optical jack or the Dolby Digital Coaxial jack.
