Dolby Pro-Logic
|
| Dolby Lab’s basic 4-channel format, widely used in ordinary theaters and for home videos. |
|
Dolby Pro Logic II
 |
| Improved version of Dolby Pro-Logic for music and movies. With a more intelligent matrix decoder, it is suitable for both stereo and surround-encoded sources. It offers “bass management” as well as the option of incorporating “width,” “dimension” and “panorama” controls. |
|
Dolby Pro Logic IIx
 |
| Dolby Pro Logic IIx is an extension of Dolby Pro Logic II. This algorithm processes native stereo and 5.1-channel content to produce 6.1 or 7.1 output channels. Dolby Pro Logic IIx expands choice in playback system configuration (allowing 5.1, 6.1 or 7.1 playback channels) and, when incorporated into an A/V amplifier or receiver, allows a convenient upgrade path from a traditional 5.1-channel sound system to 7.1 output channels. |
|
Dolby Digital
 |
| The most popular 5.1-channel home theater sound system. An improvement over Dolby Pro-Logic in that it offers: 1) Full frequency response in all channels (3Hz — 20kHz), 2) discrete surround channels, and 3) a separate track for bass only, called the Low Frequency Effects channel. |
|
Dolby Digital EX
|
| Dolby's latest surround format, this is Dolby Digital with an added center rear channel. The rear center channel is actually matrixed into the two rear channels, and is extracted upon playback. (Formerly called Dolby Digital Surround EX, or Dolby Digital Matrix 6.1.) |
|
DTS™ Digital Surround
 |
| The basic DTS 5.1 channel sound format. Uses a higher data rate than Dolby Digital. |
|
DTS™ Neo:6®
 |
| Provides 5.1 or 6.1 channels of matrix decoding from stereo matrix material. Also decodes Extended Surround matrix sound tracks and has a Music mode to expand stereo non-matrix recordings to 5.1 or 6.1 channels. |
|
DTS™ Neo:6® 96/24
 |
| Delivers 96kHz/24-bit high resolution audio for 5.1-channel/6.1-channel surround sound on DVD discs. The benefits are greater bit depths for extended dynamic range and high sampling rates for wider frequency response. |
|
DTS™ Neo:6® 96/24 ES®
 |
|
| |
|
DTS™ Digital Out
 |
| DVD player equipped with dts surround optical-digital and coaxial-digital output. |
|
DTS-ES Matrix 6.1
|
| DTS-ES uses its large bandwidth to provide a fully discrete rear center channel, as opposed to a matrixed one. |
|
DTS-ES
Discrete 6.1 |
| In this format, the back surround channel is
matrix encoded into the left and right surround channels. For playback, the three
channels are separately decoded. |
|
THX
 |
| Created by Lucasfilm, THX is a certification standard designed to determine the audio components and acoustics needed to accomplish the most accurate movie audio play back. For full effect in a home theater, the THX decoding process requires a 7.1 speaker configuration with two back-surround speakers. |
|
MP3
 |
| Short for MPEG-1 layer 3 audio, MP3 is a compression process used to shrink audio files by filtering out all noise that is not detectable to the human ear. MP3 is considered near CD-quality, but the file itself occupies approximately one tenth to one twelfth the space of the original CD format, making it the perfect medium for today’s smaller, memory based portable media players. |
|
DivX
 |
| DivX is the video compression codec developed by DivX Networks and based on the MPEG-4 compression format. Its balance of high video quality and low bit rate has made it very popular and quickly established it as the best home video format thus far. The ability to play it on newer DVD models continues to add to its popularity as DivX Networks advances its support to many new household products. This compression technology has the potential for expanding the ways we view video media in much the way MP3 has given us many new ways to listen to music. |
|
DCDi™
 |
| Invented and patented by Faroudja, Directional Correlational De interlacing (DCDi), virtually alleviates jagged oblique lines that appear when standard interlaced video is viewed on progressive scan displays, enabling the reproduction of beautiful, natural-looking moving images. |
|
HDMI
 |
Only one cable is required to carry picture and sound.
HDMI (High Definition Multimedia Interface)
can carry more than one type of media,
namely audio and video, in a single digital
interface. Yamaha AV Receivers equipped with
HDMI provide the most advanced method of
delivering high quality video signals to a home
Theater system to enable the reproduction of
DVD and satellite TV sources with HD quality.
It can also decode digital audio signals from
sources such as DVD-Audio, CD, Dolby Digital
and DTS. |
