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 AC-3 is a technology developed by Dolby Laboratories that allows us to store much more CD-quality audio in much less space than traditional CD-audio. Dolby Digital also allows us to present soundtracks in the home that offer a complete surround sound experience, just like at the movie theatre, with left, centre, and right channels, stereo surround channels and a subwoofer.

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.

Dolby Digital (AC-3) is a digital sound compression technique developed by the Dolby Laboratories Licensing Corporation. Supporting 5.1-channel surround sound, as well as stereo (2-channel) sound, this technique enables a large quantity of sound data to be efficiently recorded on a disc. However, nowadays, the understanding has become to be Dolby Digital (AC-3) = Dolby Surround = Dolby Digital 5.1.

Dish Network currently only provides Dolby Digital soundtracks on their ‘home theater’ Pay-Per-View channels 512-513 on the 119 satellite and PPV channels 520-525 on the 110 satellite. You can look for the “DD” symbol in the Electronic Program Guide (EPG) to see if the movie is broadcasted in Dolby Digital. These channels also show some movies in their original letterbox format. DISH Network will expand their DD offerings through time.

Dolby Pro Logic takes its information from a two-track-stereo format. When a movie is recorded in Dolby surround, the Stereo soundtrack is recorded on the tape. Certain sounds (the surround-channel information) are encoded. Inside the Dolby Pro Logic receiver, the Pro Logic circuitry decodes the surround information and sends it to the rear channels. The center channel is derived by removing what is equal or nearly equal in the left and right channels and sending it to the center.

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.

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.

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.

Most DVD-Video discs contain Dolby Digital soundtracks. However, it's not required. Some discs, especially those containing only audio, have PCM tracks. It's also possible for a 625/50 (PAL) disc to contain only MPEG audio, but so far MPEG audio is not widely used. Don't assume that the "Dolby Digital" label is a guarantee of 5.1 channels. A Dolby Digital soundtrack can be mono, dual mono, stereo, Dolby Surround stereo, etc.

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.

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

Yes, there are several others that have been tried over the years but haven't been widely accepted for one reason or another. These are: Ambisonics - Ambisonics is the work of a group of British academics, most notably Michael Gerzon, who built on the previous work of famed audio pioneer Alan Blumlein.

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.

Yes, DVD-V200K does have a built-in decoder with Dolby Digital (Surround) (AC-3) processing; however, the output is only 2-channel stereo. No, from the modem day definition/understanding of a so-called built-in AC-3 decoder. Regardless, you can attach the DVD-V200K to a Dolby Digital-ready (i.e., 5.1-ready) A/V receiver/processor/amplifier to enjoy the benefits of 5.1 channel surround sound audio.

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.

One of the technical specifications of DVD states that every disc must use at least one PCM or Dolby Digital soundtrack to ensure the medium's high quality throughout all its publications. Dolby Digital is a sound format that allows to have up to six different channels of sound, making for a full surround experience of your movies. One of the most common used versions of Dolby Digital is its 5.1 channel implementation.

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.

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....
