If you plan to connect the DVD player to a surround-sound receiver that is Dolby Digital ready, then a built-in decoder is necessary. If the receiver has a built-in decoder, the DVD player only needs to have the Dolby Digital passthrough.

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.

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 six-channel surround sound system found on many DVDs, sending discrete audio information to speakers at front left/right, surround left/right, centre and the subwoofer.

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.

While you won't get the same experience listening to Dolby Digital 5.1 audio on a Dolby Pro Logic system, you will notice a dramatic difference between listening in Dolby 5.1 and 2.0. Of course to take the fullest advantage of 5.1 you'd need a Dolby Digital receiver. Put simply, in order to fit all the information on one side of the DVD, the technology utilizes two layers of information. That delay is the laser reaching the end of layer 1 and finding layer 2.

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.

DD is a surround system using the digital audio compression technology. It is a six channel configuration and reproduces sound through a speaker system including front (L&R), rear (L&R), centre and sub-woofer speakers. Because the sub-woofer in the system is an auxiliary speaker, the system is called "5.1 channel system". In a Digital Versatile Disc, the surround audio data is recorded digitally in a bit-stream.

Dolby Digital 5.1 is a new format that has become more popular with the coming of DVD. This audio format offers any number of dedicated channels up to five main channels and one low frequency effect channel. Dolby Digital is the most popular current decoding method for DVDs and offers the following improvements on movie soundtracks: In most ways, all DVD players are Dolby Digital compatible. Most DVDs are compatible with DVD players without a Dolby Digital encoder.

No. You can get started with just a DVD player. DVD players have regular right and left stereo analog output jacks. Simply connect them to an A/V receiver with Dolby Pro Logic or Dolby Surround for surround sound. Also, many DVD players come with Virtual Surround, which creates surround sound with just your 2 speakers, and they don't even need Dolby Pro Logic or surround. The best part is, when you decide to go digital, you can easily upgrade to a Dolby Digital decoder and 6-speaker package.

long as the program is being broadcast in Dolby Digital audio, the PVR will record the digital audio. A Dolbly Digital indicator will appear on the Flip Bar and Program Information screen for programs that provide it.

Firstly, confirm that your digital connection (optical or coaxial) is securely made between your DVD player and 5.1 channel receiver. The Dolby Digital 5.1 signal is only transmitted out from the digital outputs on the back of the DVD player as shown below. You will not receive the Dolby Digital 5.1 signal if you are using a standard stereo RCA cable connected to the analog audio outputs on the back of the DVD player as shown below.

The The ProtecTV does not support optical or digital audio. It will support DVD players and Home Theater systems with the standard A/V cables.

We are able to offer some movies with Dolby 5.1. If your audio visual equipment supports and is set up for Dolby Digital, you will be able to hear those movies in 5.1 surround sound.

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).

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....

long as the program is being broadcast in Digital Audio, the DVR will record the digital audio portion. A Dolby Digital indicator will appear on the Flip Bar for programs broadcast in Dolby Audio.

Dolby Digital is a surround sound format that supports up to 5.1 channels of discrete multi-channel sound. Since Dolby Digital is part of the DVD standard, all DVD players support Dolby Digital in at least one of two ways. First, DVD players with digital audio output(s) allow you to connect the output of the "raw" digital audio signal to an outboard decoder, typically a function of a receiver or pre-amplifier. Second, DVD players may optionally have a built-in Dolby Digital decoder.

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.

Because the surround speakers in a home theater system are usually closer to viewers than the front speakers, both Dolby Digital and Dolby Surround Pro Logic playback require a split-second electronic delay of the surround channels. In the case of Dolby Digital, the delay ensures that the viewer hears sound from the surround and front speakers simultaneously.

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.
