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 7.1 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.

Windows Media Audio 9 Professional
Windows Media Audio 9 Professional (WMA9 Pro) is a
discrete surround format developed by Microsoft
Corporation.
WMA9 Pro can support up to 5.1/7.1 channel playback
with sampling rates up to 24-bit/96 kHz. Using the unique
WMA compression techniques, WMA9 Pro can deliver
multichannel music and soundtracks over high-speed
internet networks at low bit rates with minimal audio
degradation. Playback may be enjoyed with the Windows
Media Player 9 Series (or above) and other third-party
media players on a personal computer, or with an AV
amplifier with on-board WMA9 Pro decoding.
