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.

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.

In Mono, the original sound is picked up by one ( or more ) microphone(s). Only one signal is recorded, regardless the number of microphones that have been used, i.e. only one signal is involved in the playback stage. Disc phonographs, television, motion picture and radio all use monophonic system. 2 Channel encodes a left and right signal (this is refered to as stereo sound). Channel sound is refered to as Dolby Surround.

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.

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 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.

Xflowsion was created using cutting-edge cinematography and surround sound technology, including Dolby Digital 5.1 surround sound. If your entertainment system has a surround system, simply click on the 5.1 icon on the DVD menu to activate this feature. If you don't have a surround sound system, just click on the stereo icon. Either way, you'll be blown away by the acoustic experience.

No, the HDMI outputs on the Movie Player and the Movie Player 2 carry video and PCM stereo audio only. When using HDMI for video, you can use digital coaxial, digital optical, or analog stereo outputs for audio. No. The DVD CCA License does not permit the use of RGBHV video output during DVD playback. The Kaleidescape Movie Player 2 supports both HDMI and component video (YPbPr) for high-quality video output.

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....

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.

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 is a matrix decoder that decodes the four channels of surround sound that have been encoded onto the stereo soundtracks of Dolby Surround program material such as VHS movies and TV shows. Dolby Surround (or Dolby matrix!) is a matrix encoding process that in essence "folds" Left, Center, Right, and Surround channels onto stereo soundtracks. A Pro Logic decoder "unfolds" the four channels on playback (without a Pro Logic decoder, the encoded program plays in regular stereo).

Surround sound systems require a number of additional speakers arranged around the room. Discs are formatted so that different speakers play different sounds from a variety of sound “channels” resulting in a surround effect. Those without multiple speaker sound systems shouldn’t have a problem playing any encoded discs, although the benefits will not necessarily be apparent without the correct equipment.

Using the "Bass Management System" on your surround processor, set the front Left and Right speakers to "large" (full range). Connect the Left and Right outputs on the processor to the Left and Right inputs on the Bag End Infrasub-18, respectively. Now, connect the Left and Right hi pass outputs on the Bag End Infrasub-18 to the Left and Right inputs on your amplifier (which powers the front Left and Right speakers), respectively.

Indeed it will. DOOM 3 will have the latest in Dolby 5.1 audio surround sound for full gaming experience!

DVRs with HDTV recording capability can record multichannel audio information. Currently there are only a few HD-capable DVRs. Keep in mind, though, that even if your DVR can't record in 5.1, an A/V receiver with Dolby® Pro Logic® II or Dolby Pro Logic IIx can expand any 2-channel signal into convincing 5.1, 6.1, or even 7.1 surround sound.

A bay is essentially a curved inlet of the sea enclosed by a coastline such as the Chesapeake Bay. A sound is a broad channel between an island and the mainland, such as the Pamlico, Albemarle, and Currituck Sounds.

No. Digital Sound Projector does not merely utilize 42 speakers, but 42 speakers individually powered by 42 individual digital amplifiers and individually controlled by a special DSP chip. They are not 42 speakers sending out the same signal, but 42 speakers sending 42 different signals to achieve true multi-channel surround-sound enjoyment from a single component.
