Dolby Digital Plus delivers multi-channel audio programs of
up to 7.1 channels (*) and supports multiple programs in a
single encoded bitstream with the maximum bit rate
potential of up to 6 Mbps and the maximum bit rate
performance of up to 3 Mbps on HD DVD and 1.7 Mbps on
Blu-ray Disc, and it outputs Dolby Digital bitstreams for
playback on existing Dolby Digital systems. Dolby Digital
Plus can accurately reproduce the sound originally intended
by directors and producers.
It also features multi-channel sound with discrete channel
output, interactive mixing and streaming capability in
advanced systems. Supported by High-Definition Media
Interface (HDMI), a single-cable digital connection is
possible for high-definition audio and video.
Dolby TrueHD
Dolby TrueHD is the next-generation lossless encoding
technology developed for high-definition optical discs in the
upcoming era. Dolby TrueHD delivers tantalizing sound that
is bit-for-bit identical to the studio master, unlocking the true
high-definition entertainment experience on high-definition
optical discs in the next generation. When coupled with
high-definition video, Dolby TrueHD offers an
unprecedented home theater experience with stunning
sound and high-definition picture.
It supports bit rates of up to 18 Mbps and records up to 8 full-
range channels (*) individually with 24-bit/96 kHz audio. It
also features extensive metadata including dialogue
normalization and dynamic range control. Supported by
High-Definition Media Interface (HDMI), a single-cable
digital connection is possible for high-definition audio and
video.
* HD DVD and Blu-ray Disc standards currently limit their
maximum number of audio channels to eight, whereas
Dolby Digital Plus and Dolby TrueHD support more than
eight audio channels.

DTS
The DTS technologies are explained below. See
www.dtstech.com for more detailed information.
DTS Digital Surround
DTS Digital Surround is a 5.1-channel audio coding system
from DTS Inc. now widely used for DVD-Video, DVD-Audio,
5.1 music discs, digital broadcasts, and video games. It can
deliver up to six discrete audio channels, comprising five full
range channels, including an LFE channel. Higher sound
quality is achieved through the use of a low compression
rate, and high rates of transmittance during playback.
DTS-ES
DTS-ES (the ES stands for Extended Surround) is a decoder
that is capable of decoding both DTS-ES Discrete 6.1 and
DTS-ES Matrix 6.1 encoded sources. DTS-ES Discrete 6.1
gives ‘true’ 6.1 channel sound, with a completely separate
(discrete) surround back channel. DTS-ES Matrix 6.1 has a
surround back channel matrixed into the surround left/right
channels. Both sources are also compatible with a
conventional DTS 5.1 channel decoder.
DTS Neo:6
DTS Neo:6 can generate 6.1 channel surround sound from
any matrixed stereo source (such as video or TV) and from
5.1 channel sources. It uses both the channel information
already encoded into the source, as well as its own
processing to determine channel localization (with two
channel sources, the “.1” subwoofer channel is generated by
bass management in the receiver). Two modes (Cinema and
Music) are available using DTS Neo:6 with two channel
sources.
DTS 96/24
DTS 96/24 is an extension of the original DTS Digital
Surround which offers high quality 96 kHz/24-bit audio using
a DTS 96/24 decoder. This format is also fully backward
compatible with all existing decoders. This means that DVD
players can play this software using a conventional DTS 5.1
channel decoder.
DTS-EXPRESS
DTS-EXPRESS
is a low-bitrate encoding technology
supporting up to 5.1 channels with fixed data transfer rates.
This format is incorporated with sub audio on HD DVD and
secondary audio on Blu-ray Disc while boasting the potential
applicability to upcoming broadcasts and memory audio
contents.
DTS-HD Master Audio
DTS-HD Master Audio is a technology that delivers master
audio sources recorded in a professional studio to listeners
without any loss of data, preserving audio quality. DTS-HD
Master Audio adopts variable data transfer rates, facilitating
data transfer to the maximum rate of 24.5 Mbps in the
Blu-ray disc format, 18.0 Mbps in the HD-DVD format, which
by far exceeds that of a standard DVD. These high data
transfer rates enable lossless transmission of 96 kHz/24-bit
7.1-channel audio sources without deteriorating the quality
of the original sound. DTS-HD Master Audio is an
irreplaceable technology that can reproduce sound faithfully
as intended by the creator of music or movies.
