with Dolby Digital program material, "Dolby Digital" on a component such as a DVD player indicates that it incorporates Dolby Digital decoding, but not the number of channels. Many program sources, including all DVD players and digital cable set-top boxes, provide a built-in, two-channel Dolby Digital decoder with analog stereo outputs (see question 7). For 5.

Dolby Digital programs can deliver surround sound with up to five discrete full-range channels: Left, Center, Right, Left Surround, Right Surround-plus a sixth channel for powerful low-frequency effects. As it needs only about one-tenth the bandwidth of the others, the LFE channel is referred to as a ".1" channel (and sometimes erroneously as the "subwoofer" channel).

The technology behind 5.1-channel Dolby Digital provides two surround channels, instead of the one from Dolby Surround, for more precise localization of sounds and a more convincing, realistic ambience. Also, Dolby Digital's surround channels cover the entire audible range (20 Hz-20,000 Hz), whereas the range of Dolby Surround's single surround channel is limited (100 Hz-7,000 Hz). The increased range of Dolby Digital further heightens realism and gives sound mixers more creative freedom.

No. Dolby Digital soundtracks can provide anything from mono to full 5.1-channel surround sound. DVDs of movies can even carry multiple versions of the soundtrack that differ in number of channels. A disc might contain a 5.1-channel sound mix with the dialogue in one language, a two-channel mix encoded in Dolby Surround in another language, and a mono track with the director's comments or other supplementary information.

To receive the 5.1-channel soundtrack on programs such as the Dolby Digital-encoded theatrical films broadcast by DIRECTV on its pay-per-view channels, you need a new satellite receiver that provides a Dolby Digital output (the "Digital" output on conventional satellite receivers does not handle Dolby Digital signals). As with other Dolby Digital components, you connect the Dolby Digital coaxial or optical output to a digital input on your Dolby Digital decoder unit.

Dolby Digital audio is available via laser discs, DVD-Video discs, DVD-ROM discs for computers, digital cable systems, direct broadcast satellite (DBS) systems, and digital broadcast TV (DTV). They are usually identified with the Dolby Digital logo.

Dolby Digital is a system capable of multi channel digital audio, coded using technology previously known as AC-3, often abbreviated as DD.

Nobody is more enthusiastic about multichannel sound than Dolby Laboratories. However, we also recognize the importance of standardization, compatibility, and the reluctance of producers to release, and retailers to stock, more than one version of a given program. As a result we will not release CDs with Dolby Digital soundtracks, or encourage others to do so. channel music CDs, such as those released by DTS, are non-standard; they don't provide the PCM audio specified by the CD "Red Book.

Dolby technologies put you in the center of your movie-going experience. You will hear five full-range discreet channels, plus a subwoofer channel that coves the bottom one-tenth of the audible range - these are the technologies that create the experience. The dynamic range (the ratio of the loudest sounds to the softest) is significant and the full-range surround channels make lifelike special effects possible-think helicopters flying overhead.

Dolby® Digital technology is an advanced form of digital audio coding that makes it possible to store and transmit high-quality digital sound far more efficiently than was previously possible. First used in movie theaters in 1992, Dolby Digital technology is the result of decades spent by Dolby Laboratories developing signal-processing systems that exploit the characteristics of human hearing.

Discs in countries such as the US that use the NTSC broadcast TV standard must provide at least one soundtrack in either of two formats: Dolby Digital or PCM (the format used on CDs). In countries using the PAL TV standard, including much of Europe, the discs must include at least one soundtrack in any one of three formats: Dolby Digital, PCM, or MPEG. Due to these requirements and the options they permit, not all discs may have Dolby Digital soundtracks.

Dolby digital is a sound format featuring six-channel sound with separate left and right sounds and a low frequency-effects channel. Dolby digital is a standard when it comes to sound formats for DVDs, set-top boxes, etc.

Yes. We support the latest Dolby Digital technology. Customers will need a Dolby Digital receiver with a coaxial digital input.

That depends on the computer's configuration and its DVD/audio card, so check the specifications carefully to be sure you get the audio capability you want. Most PCs can be connected to external playback equipment ranging from amplified stereo speakers to a full 5.1-channel playback system. The latter include not only full home theater systems, but compact, multichannel PC speaker systems incorporating amplifiers and Dolby Digital and/or Dolby Surround Pro Logic decoding.

is a generic description of a multi-channel sound system. All of these surround sound types use 5.1 channel decoding to provide surround sound....

Make sure you are using an S/PDIF connection, and that, in the Settings category, you select Dolby Digital under Audio Output

Consumer grade DVD recorders all have the ability to play back all Dolby Digital and DTS source material, when used with an AV receiver. However, DVD recorders only have analog stereo audio inputs for recording audio, which is then encoded into two-channel Dolby Digital. The output of the recorded audio can be accessed either through the analog stereo outputs or the digital audio outputs of the DVD recorder. Although, DVD recorders cannot record in 5.

Dolby Digital can be enjoyed via DVDs, DVD recordable and playback discs for computers, laser discs, digital cable systems, direct broadcast satellite (DBS) and direct-to-home (DTH) systems, and digital broadcast television (DTV/DVB). Sources are usually identified with the Dolby Digital logo.

Digital cable television systems can provide you with another source of programming for Dolby Digital playback. The number of channels with Dolby Digital cable transmissions varies as with DTV broadcasts and other Dolby Digital program sources.
