Glossary of audio decoding format
This is a glossary of the technical terms related to audio decoding format used in this
manual.
Dolby Atmos
Introduced first in the cinema, Dolby Atmos brings a revolutionary sense of dimension and
immersion to the Home Theater experience. Dolby Atmos is an adaptable and scalable object
based format that reproduces audio as independent sounds (or objects) that can be accurately
positioned and move dynamically throughout the 3 dimensional listening space during playback.
A key ingredient of Dolby Atmos is the introduction of a height plane of sound above the listener.
Dolby Atmos Stream
Dolby Atmos content will be delivered to your Dolby Atmos enabled AV receiver via Dolby Digital
Plus or Dolby TrueHD on Blu-ray Disc, downloadable files and streaming media. A Dolby Atmos
stream contains special metadata that describes the positioning of sounds within the room. This
object audio data is decoded by a Dolby Atmos AV receiver and scaled for optimum playback
through Home Theater speaker systems of every size and configuration.
Dolby Digital
Dolby Digital is a compressed digital audio format developed by Dolby Laboratories, Inc. that
supports 5.1-channel audio. This technology is used for audio on most DVD disc.
Dolby Digital Plus
Dolby Digital Plus is a compressed digital audio format developed by Dolby Laboratories, Inc. that
supports 7.1-channel audio. Dolby Digital Plus remains fully compatible with the existing
multichannel audio systems that support Dolby Digital. This technology is used for audio
streaming services on the Internet and audio on BD (Blu-ray Disc).
Dolby Surround
Dolby surround is a next generation surround technology that intelligently up mixes stereo; 5.1
and 7.1 content for playback through your surround speaker system. Dolby surround is
compatible with traditional speaker layouts, as well as Dolby Atmos enabled playback systems
that employ in-ceiling speakers or products with Dolby speaker technology.
Dolby TrueHD
Dolby TrueHD is an advanced lossless audio format developed by Dolby Laboratories, Inc. to
offer a high-definition home theater experience with the quality of the studio master. Dolby TrueHD
can carry up to eight channels of 96 kHz/24-bit audio (up to six channels of 192 kHz/24-bit audio)
simultaneously. This technology is used for audio on BD (Blu-ray Disc).
DTS 96/24
DTS 96/24 is a compressed digital audio format that supports 5.1-channel and 96 kHz/24-bit
audio. This format remains fully compatible with the existing multichannel audio systems that
support DTS Digital Surround. This technology is used for music DVDs, etc.
DTS Dialog Control
DTS Dialog Control allows you to boost the dialog. This can be useful in noisy environments to
help make the dialog more intelligible. People with impaired hearing may also benefit. Note that
the content creator may disable the use of this feature in the mix, so that DTS Dialog Control may
not always be available. Note that updates to your AVR may add more functionality to DTS Dialog
Control or increase the range of the feature.
DTS Digital Surround
DTS Digital Surround is a compressed digital audio format developed by DTS, Inc. that supports
5.1-channel audio. This technology is used for audio on most DVD discs.
DTS-ES
DTS-ES creates total 6.1-channel audio from 5.1-channel sources that are recorded with DTS-ES.
This decoder adds a surround back sound to the original 5.1-channel sound. In the DTS-ES Matrix
6.1 format, a surround back sound is recorded in the surround channels, and in the DTS-ES
Discrete 6.1 format, a discrete surround back channel is recorded.
DTS Express
DTS Express is a compressed digital audio format that supports 5.1-channel audio and allows a
higher compression rate than the DTS Digital Surround format developed by DTS, Inc. This
technology is developed for audio streaming services on the Internet and secondary audio on BD
(Blu-ray Disc).
DTS-HD High Resolution Audio
DTS-HD High Resolution Audio is a compressed digital audio format developed by DTS, Inc. that
supports 7.1-channel and 96 kHz/24-bit audio. DTS-HD High Resolution Audio remains fully

DTS Neo: 6
DTS Neo: 6 enables 6-channel playback from 2-channel sources. There are two modes available:
"Music mode" for music sources and "Cinema mode" for movie sources. This technology provides
discrete full-bandwidth matrix channels of surround sound.
DTS:X
DTS:X is the next generation object-based, multi-dimensional audio technology from DTS.
Unbound from channels, DTS:X conveys the fluid movement of sound to create an incredibly rich,
realistic and immersive soundscape - in front of, behind, beside and above the audience - more
accurately than ever before. DTS:X offers the ability to automatically adapt the audio to the
speaker layout that best fits the space, from a television's built-in speakers to a home surround
theater system to a dozen or more speakers in a commercial cinema. Immerse yourself at
