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 multi-channel digital signal format developed by Dolby
Laboratories.
A total of 5.1-channels are played: 3 front channels (“FL”, “FR” and “C”), 2
surround channels (“SL” and “SR”) and the “LFE” channel for low
frequency effects.
Because of this, there is no crosstalk between channels and a realistic
sound field with a “three-dimensional” feeling (sense of distance,
movement and positioning) is achieved. This delivers a thrilling surround
sound experience in the home.
Dolby Digital Plus
Dolby Digital Plus is an improved Dolby Digital signal format that is
compatible with up to 7.1-channels of discrete digital sound and also
improves sound quality thanks to extra data bit rate performance. It is
upwardly compatible with conventional Dolby Digital, so it offers greater
flexibility in response to the source signal and the conditions of the
playback device.
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.
