■ Dolby Surround
Dolby Surround uses a 4-channel analog recording system to 
reproduce realistic and dynamic sound effects: 2 front left and right 
channels (stereo), a center channel for dialog (monaural), and a 
surround channel for special sound effects (monaural). The 
surround channel reproduces sound within a narrow frequency 
range. Dolby Surround is widely used with nearly all video tapes 
and laser discs, and in many TV and cable broadcasts as well. The 
Dolby Pro Logic decoder built into this unit employs a digital signal 
processing system that automatically stabilizes the volume on each 
channel to enhance moving sound effects and directionality.
■ Dolby TrueHD
Dolby TrueHD 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 HD DVD and 
as an optional audio standard for 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, Dolby TrueHD can carry up to 8 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, Dolby TrueHD also remains fully 
compatible with the existing multichannel audio systems and retains 
the metadata capability of Dolby Digital, allowing dialog 
normalization and dynamic range control.
■ DSD
Direct Stream Digital (DSD) technology stores audio signals on 
digital storage media, such as Super Audio CDs. Using DSD, 
signals are stored as single bit values at a high-frequency sampling 
rate of 2.8224 MHz, while noise shaping and oversampling are used 
to reduce distortion, a common occurrence with very high 
quantization of audio signals. Due to the high sampling rate, better 
audio quality can be achieved than that offered by the PCM format 
used for normal audio CDs.
■ DTS 96/24
DTS 96/24 offers an unprecedented level of audio quality for multi-
channel sound on DVD video, and is fully backward-compatible 
with all DTS decoders. “96” refers to a 96 kHz sampling rate 
compared to the typical 48 kHz sampling rate. “24” refers to 24-bit 
word length. 
DTS 96/24 offers sound quality transparent to the original 96/24 
master, and 96/24 5.1-channel sound with full-quality full-motion 
video for music programs and motion picture soundtracks on DVD 
video.
■ DTS Digital Surround
DTS digital surround was developed to replace the analog 
soundtracks of movies with a 6.1-channel digital sound track, and is 
now rapidly gaining popularity in movie theaters around the world. 
DTS, Inc. has developed a home theater system so that you can 
enjoy the depth of sound and natural spatial representation of DTS 
digital surround in your home. This system produces practically 
distortion-free 6-channel sound (technically, front left and right, 
center, surround left and right, and LFE 0.1 (subwoofer) channels 
for a total of 5.1 channels). This unit incorporates a DTS-ES 
decoder that enables 6.1-channel reproduction by adding the 
surround back channel to the existing 5.1-channel format.
■ 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 “http://www.hdmi.org/”.
