Dolby 3 Stereo
Uses front left, centre and right speakers of a home cinema TV to create an enhanced sound stage without using rear speakers.

Dolby 3D Surround
Using Dolby processing to create cinema surround without cables or rear speakers.

Dolby Digital
Dolby Digital produces 5 discrete (perfectly separated) sound channels and a dedicated LFE (Low Frequency Effects) subwoofer channel. For this reason it is known as a 5.1 channel system (the .1 indicating the subwoofer channel that has limited frequency for just the low audio frequencies) Dolby Digital has all the benefits of an all digital system in terms of clear sound without distortion and noise. Compared to Dolby Pro Logic, the sonic improvement almost corresponds to stepping up from cassette tape to CD Dolby Digital is used in a variety of video/audio formats world wide including. DVD, Laserdisc, Computer Games, Radio and TV broadcasting. Dolby Digital was originally known as AC-3, this is still the name of the encoding used.

Dolby Digital 5.1
Offers true cinema surround sound when using a digital source such as DVD. Utilising two front speakers, one front dialogue speaker, two rear effects speakers and a subwoofer for low frequency effects.

Dolby Digital Decoder
Dolby Digital Decoder built in.

Dolby Digital EX
Dolby Digital EX adds a centre-surround channel to the existing 5.1 set-up... Dolby Digital EX is the mixing of mono content from the two stereo rear speakers into the rear surround channel in a similar way to DTS-ES Matrixed However it is not discrete so not a true 6.1 system like DTS-ES Discrete

Dolby HX Pro
Dolby HX Pro makes it possible to record loud musical passages with fewer high-frequency losses and less distortion.

Dolby Pro-Logic
The most widely used Home Entertainment process. Produces a surrounding sound field with Dolby Surround or Dolby Stereo encoded software. This includes practically all major films from the late seventies and onwards available on VHS videotape, laserdisc, DVD or from stereo TV. It has 4 perceivable channels of sound all derived from a stereo sound track, (Left Front, Centre, Front Right and Rear Surround) This is achieved by redirecting out of phase information (Normally deliberately encoded in to the stereo tracks) to the rear speakers. Information going to the centre channel (Pro-Logic) processes and mixes all information that is lacking in any stereo content Dolby Pro Logic 2 is the updated version of Pro-Logic that gives stereo surround speaker channels.

Dolby Pro-Logic 2
Pro Logic II decoding reproduces 5.1-channel surround sound from any 2-channel sources: DVD, VHS, television broadcasts, radio, and CDs. Dolby Pro Logic II uses matrix decoding technology that has been dramatically improved over ordinary Pro Logic. With Pro Logic II, for instance, the Surround (Rear) channels are in stereo (only mono with Pro Logic) and playback covers the full frequency range (only up to 7 kHz with Pro Logic). These improvements let you enjoy a wide variety of 2-channel sources with the exciting effects of 5.1- channel surround sound. It's not as good as discrete (Separate independent channel) formats like Dolby Digital and DTS, but it's more involving than ordinary stereo and a much better home cinema experience than Dolby Pro Logic.

dpi Resolution
Number of Dots Per sq Inch.

DTS
Digital Theatre System. An alternative to Dolby Digital, DTS encodes six-channel digital surround sound and is used in some cinemas and on some DVD's.

DTS
DTS produces 5 discrete (perfectly separated) sound channels and a dedicated LFE (Low Frequency Effects) subwoofer channel. For this reason it is known as a 5.1 channel system (the .1 indicating the subwoofer channel that has limited frequency for just the low audio frequencies) DTS has all the benefits of an all digital system in terms of clear sound without distortion and noise. DTS is used in a variety of video/audio formats world wide including. DVD, Laserdisc, Computer Games, Radio and TV broadcasting. DTS boasts a higher bit rate than its competing format Dolby Digital and therefore can provide higher sound quality (Due to there being less compression).

DTS-ES
DTS Extended Surround adds a centre-surround channel to the existing 5.1- channel set-up. DTS-ES brings these soundtracks into the home in DTS quality and is the only home format that can deliver all 6.1-channels discretely. All sounds will be heard, whether played back as discrete, matrix or on a 5.1 system. It is compatible with all DVD-Video players and is accessible through the digital output. The DTS coding system has a "core + extension" structure. The "core" represents the DTS data as has been known since the first home decoders. The "extension" can carry data for future applications or enhancements of any sort. All DTS decoders recognize and use the core data. Basic decoders ignore the extension data, while advanced decoders can make use of it. The extension for DTS-ES Discrete carries the additional 6th channel and is totally independent of the other channels. DTS-ES Matrixed is the mixing of mono content from the two stereo rear speakers into the rear surround channel in a similar way to Dolby Digital EX.

DTS-ES Discrete 6.1 / DTS-ES Matrix 6.1
A new 6.1 channel surround sound format. The extra channel is intended to drive one or more 'back surround' or centre rear speakers located between the left and right ones. The sixth channel with be 'ignored' by the regular 5.1 DTS decoders, hence the need fir DTS ES Matrix 6.1 This Format like Dolby Digital EX encodes the back surround channel via an analogue matrix, and delivers it via the rear channels.

DTS-Neo:6 Cinema
DTS Neo:6 is an advanced matrix decoder. It will take any two-channel source and expand it into five or six channels, depending on the equipment used and speakers connected. Two-channel sources include VHS tapes, broadcast television, stereo CDs and DVDs. DTS Neo:6 provide separate, optimized modes for stereo music materials and matrix surround motion picture soundtracks. DTS Neo:6 also decodes a centre-surround channel from DTS-ES Extended Surround matrix soundtracks. DTS Neo:6 works along the same lines as the rival decoding technology Dolby Pro-Logic 2

Dual Screen Plus
