Dolby Digital has been selected as the default format for DVD video, standard 2 channel audio playback and HDTV ??Digital broadcasting??. Dolby Digital features two independent surround channels giving same full range as the three front channels. Plus it adds a Low Frequency Effect channel ??LFE??. Dolby Digital accomplishes this by using a technique called compression. Digital Theater Systems ??DTS?? uses the same concept but implements a lower compression rate.

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....

Dolby Digital & DTS (Digital Theatre Systems) are two different sound formats found on DVD (although DTS to a lesser extent, unfortunately). Both formats offer up to 6.1 channels of high quality surround sound but thanks to less compression DTS edges slightly ahead of Dolby Digital in terms of quality. Yes. Selected DVDs contain Dolby Digital &/or DTS soundtracks with an additional centre rear channel ? these are known as Dolby Digital EX & DTS-ES.

The Xbox does support Dolby Digital 5.1 channel surround sound while playing games, as well DTS while playing DVDs. To get DD 5.1 or DTS you will need the official Xbox Advanced AV Pack (which also supports S-video), or the official Xbox High Definition AV Pack.

Dolby Digital is 16 bits of PCM Linear Tracking that is compressed. DTS is 20 bits of Master quality audio that is not compressed. Dolby Digital and DTS are similar in that they are both digital lossy audio coding technologies, which means they use "perceptual" data reduction techniques that are based on the characteristics of human hearing to mask the process, thereby preserving high fidelity sound. This is necessary in order to fit the typical 5.

Yes, all of our systems can perform pass-through via Digital Coax or Optical connection to your reciever. SLI will not improve either the performance or picture quality of HDTV. It provides significant performance increases in playing high-end video games and allows you to play these games in HDTV level resolutions

All of these are methods of creating a more convincing soundfield that seems to "surround" the viewer (at least on Laserdisc, see explanation on Dolby Digital). They require more than 2 speakers. The most widespread surround sound system is Dolby Surround. Dolby surround is an analog system that decodes 2 channels into 4 channels, Left, Right, Center and Surround. The center channel is used to anchor dialog to the screen and the surround channels are used to create ambiance.

This is a BIG question. This one point alone causes much confusion amongst filmmakers. Please take a moment and read this paragraph carefully. If you need more information after that, please contact either Gnome Productions or Magnolia Studios and we will help you out. First, about THX. THX [tm] is not something that you DO to your soundtrack, it is just a set of sound reproduction or mixing conditions that optimize the sound of your film's soundtrack in exhibition.

Both methods are what's known as lossy data compression schemes where some information that is masked by more prominent data is thrown away. This is done in order to fit a lot of data through a small data pipe. Dolby Digital (formerly called AC-3) takes 6 channels of 48kHz/24 bit information and compresses it at about an 11 to 1 ratio to an a maximum bit rate of 640kbps, although 384 is the average data rate used. DTS compresses at about a 3 to 1 ratio at an average data rate of 1.4Mbps.

Dolby Digital-EX and DTS-ES add a rear center channel to the typical 5.1 surround setup to make it 6.1. THX-EX is the processing technique to match the new soundtracks.

The DTS sound track on a DVD will be one of three sound tracks available on the disc. A DTS disc will have a stereo, Dolby Digital and DTS soundtrack to choose from. Most discs have an option menu, which allows you to make certain selections regarding audio, language, and other special features. Under the audio option menu, you will find the various selections for the type of sound track you wish to select.

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.

Many DVDs offer a choice of sound formats including Dolby Digital and DTS (Digital Theater Systems). The sound is encoded on the DVD so you will need a decoder to experience the full surround sound effect. However, all DVD players will deliver conventional stereo sound without a decoder. Once you have reviewed a movie we check that it is a reasonable length of review and suitable for displaying on the website. This may take a few days.

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.

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).

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.

This depends entirely on you sound card or decoder card. If either of these have SP/DIF digital out it should be possible in theory to output a digital signal to an appropriate amplifier. Sound card like the Sound Blaster Live (Full) and some versions of the Vortex 2 cards have suitable SP/DIF out's, as do most dedicated decoder cards such as the Real magic Hollywood + cards. You may need to look in the manuals for your kit for instructions on how to connect things together.

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.

Digital Theater Systems is a surround system that offers 5.1 channels of dynamic digital audio. This system on which some DVD disc record movies, reproduce the soundtrack with dynamic hi-fidelity as would be reproduced in a theater.

Dolby Stereo is a four track analog sound format. It has Left, Center and Right channels behind the screen and one common Surround channel behind and to the side of the audience. However, since conventional film can carry only two tracks of optical sound information, the four Dolby Stereo tracks are encoded into two tracks by a processor in the mixing studio. These two tracks are read by the Dolby Stereo processor in the theatre and converted once again into four tracks.

Almost every DVD contains audio in Dolby Digital format. DTS is an optional audio format that can be added to a disc in addition to Dolby Digital audio. Dolby Digital and DTS can store mono, stereo, and multichannel audio (usually 5.1 channels). Every DVD player in the world has an internal Dolby Digital decoder. The built-in 2-channel decoder turns Dolby Digital into standard analog stereo audio, which can be fed to almost any type of audio equipment (receiver, TV, boombox, etc.

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.

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.
