DTS Express
DTS Express is an advanced audio technology for the
optional feature on Blu-ray Disc or HD DVD, which
offers high-quality, low bit rate audio optimized for
network streaming, and Internet applications. DTS
Express is used for the Secondary Audio feature of Blu-
ray Disc or the Sub Audio feature of HD DVD. These
features deliver audio commentaries (for example, the
additional commentaries made by the director of a film)
on demand by the users via the Internet, etc. DTS Express
signals are mixed down with the main audio stream on the
player component, and the component sends the mixed
audio stream to the AV receivers/amplifiers via digital
coaxial, digital optical, or analog connections.

DTS-HD Master Audio
DTS-HD Master Audio is an advanced lossless audio
technology developed for high-definition disc-based
media including HD DVD and Blu-ray Disc. Selected as a
mandatory audio standard for both HD DVD and Blu-ray
Disc, this technology delivers sound that is bit-for-bit
identical to the studio master, offering a high-definition
home theater experience. Supporting bitrates up to 18.0
Mbps for HD DVD and up to 24.5 Mbps for Blu-ray Disc,
DTS-HD Master Audio can carry up to 7.1 discrete
channels of 24-bit/96 kHz audio simultaneously.
Supported by HDMI version 1.3 and designed for the
optical disc players and AV receivers/amplifiers of the
future, DTS-HD Master Audio also remains fully
compatible with the existing multichannel audio systems
that incorporate DTS Digital Surround.
■
DTS-HD High Resolution Audio
DTS-HD High Resolution Audio is an high resolution
audio technology developed for high-definition disc-based
media including HD DVD and Blu-ray Disc. Selected as
an optional audio standard for both HD DVD and Blu-ray
Disc, this technology delivers sound that is virtually
indistinguishable from the original, offering a high-
definition home theater experience. Supporting bitrates up
to 3.0 Mbps for HD DVD and 6.0 Mbps for Blu-ray Disc,
DTS-HD High Resolution Audio can carry up to 7.1
discrete channels of 24-bit/96 kHz audio simultaneously.
Supported by HDMI version 1.3 and designed for the
optical disc players and AV receivers/amplifiers of the
future, DTS-HD High Resolution Audio also remains
fully compatible with the existing multichannel audio
systems that incorporate DTS Digital Surround.

HDMI
HDMI (High-Definition Multimedia Interface) is the first
industry-supported, uncompressed, all-digital audio/video
interface. Providing an interface between any source (such
as a set-top box or AV receiver) and an audio/video
monitor (such as a digital television), HDMI supports
standard, enhanced or high-definition video as well as
multi-channel digital audio using a single cable. HDMI
transmits all ATSC HDTV standards and supports 8-
channel digital audio, with bandwidth to spare to
accommodate future enhancements and requirements.
When used in combination with HDCP (High-bandwidth
Digital Content Protection), HDMI provides a secure
audio/video interface that meets the security requirements
of content providers and system operators. For further
information on HDMI, visit the HDMI website at

LFE 0.1 channel
This channel reproduces low-frequency signals. The
frequency range of this channel is from 20 Hz to 120 Hz.
This channel is counted as 0.1 because it only enforces a
low-frequency range compared to the full-range
reproduced by the other 5/6 channels in Dolby Digital or
DTS 5.1/6.1-channel systems.
■
MP3
One of the audio compression methods used by MPEG. It
employs the irreversible compression method, which
achieves a high compression rate by thinning out the data
of hardly audible part to the human ears. It is said to be
capable of compressing the data quantity by about 1/11
(128 kbps) while maintaining a similar audio quality to
music CD.
■
Neo:6
Neo:6 decodes the conventional 2-channel sources for 6-
channel playback by the specific decoder. It enables
playback with the full-range channels with higher
separation just like digital discrete signal playback. There
are two modes available: “Music mode” for music sources
and “Cinema mode” for movie sources.
