DTS Express
DTS Express is an audio format supporting low bit
rates (max. 5.1 channels, 24 to 256 kbps).
Manufactured under license under U.S. Patent
#s: 5,451,942; 5,956,674; 5,974,380; 5,978,762;

DTS-HD
This audio technology provides higher sound quality
and enhanced functionality than the conventional
DTS and is adopted as an optional audio for Blu-ray
Disc. This technology supports multi-channel, high
data transfer speed, high sampling frequency, and
lossless audio playback. Maximum 7.1-channels are
supported in Blu-ray Disc.
DTS-HD High Resolution Audio
DTS-HD High Resolution Audio is an improved
version of the conventional DTS, DTS-ES and
DTS 96/24 signals formats, compatible with
sampling frequencies of 96 or 48 kHz and up to
7.1 channels of discrete digital sound. High data
bit rate performance provides high quality sound.
This format is fully compatible with conventional
products, including conventional DTS digital
surround 5.1-channel data.
DTS-HD Master Audio
DTS-HD Master Audio is a lossless audio format
created by Digital Theater System (DTS). This
format provides the facility to support up to 8 audio
channels with a sampling frequency of 96kHz/24bit
resolution and up to 6 audio channels with a
sampling frequency of 192kHz/24bit resolution.
It is fully compatible with conventional products,
including conventional DTS digital surround
5.1-channel data.
Dynamic range
The difference between the maximum undistorted
sound level and the minimum sound level that is
discernible above the noise emitted by the device.
F
Finalise
This is processing that enables playing back of
disc of BD/DVD/CD, which was recorded using a
recorder, by other players.
H
HDCP
When transmitting digital signals between devices,
this copyright protection technology encrypts
the signals to prevent content from being copied
without authorization.
HDMI
This is an abbreviation of High-Definition Multimedia
Interface, which is an AV digital interface that can
be connected to a TV or amplifier. Video signal and
audio signal can be connected using 1 cable.
I
Interlacing (interlaced scanning)
This conventional method used to project images
on a TV displays 1 frame of image in half and half,
respectively as 2 fields.
Interactive audio
Audio such as click sound that is generated during
operation and is recorded in the title of BD-Videos.
J
JPEG (Joint Photo graphic Experts Group)
This is a still picture data compression standard. Its
ability to reduce the size of a file with relatively little
deterioration in image quality means that it is widely
used for storing images in video cameras, etc.
L
Linear PCM
This signal is uncompressed PCM (Pulse Code
Modulation) signal. This is the same system as the
CD audio but this uses 192 kHz, 96 kHz, and 48 kHz
sampling frequencies in Blu-ray Disc or DVD and
provides higher sound quality than CD.
M
MP3 (MPEG Audio Layer-3)
This is an internationally standardized audio data
compression scheme, using the “MPEG-1” video
compression standard. It compresses the data
volume to about one eleventh its original size while
maintaining sound quality equivalent to a music CD.
MPEG (Moving Picture Experts Group), MPEG-2,
MPEG-4
These are the names for digital compression format
standards used for the encoding of video and audio.
Video standards include “MPEG-1 Video”, “MPEG-
2 Video”, “MPEG-4 Visual”, “MPEG-4 AVC”. Audio
standards include “MPEG-1 Audio”, “MPEG-2
Audio”, “MPEG-4 AAC”.
Explanation of terms
P
Picture-in-picture
This BD-Video function allows you to view making
or commentary scenes in the secondary video
while viewing the main story in the primary video.
Popup menu
This menu recorded in Blu-ray Disc software.
While playing back a Blu-ray Disc, this menu can
be displayed on the front of the screen and can be
operated.
Primary audio
This audio signal is recorded in the main story in
BD-Video.
Progressive (sequential scanning)
This is a scanning system of video signal that
displays 1 frame of video as one image. Compared
to the interlace system, this system provides
images with less flickering and bleeding.
Protection circuit
This is a function to prevent damage to components
within the power supply when an abnormality such
as an overload or excess voltage occurs for any
reason.
In this unit, the power indicator blinks and the unit
enters standby mode when an abnormality occurs.
R
Rating
Depending on the age of the viewer, this function
restricts playing back of BD-Video or DVD-Video.
This unit can be set to restrict viewing in 0 to 254
level for BD-Video, and 1 to 8 level for DVD-Video.
Region code
This code indicates country or region where the
Blu-ray Disc or DVD-Video can be played back.
S
Sampling frequency
Sampling involves taking a reading of a sound wave
(analog signal) at regular intervals and expressing
the height of the wave at each reading in digitized
format (producing a digital signal).
The number of readings taken in one second is
called the “sampling frequency”. The larger the
value, the closer the reproduced sound is to the
original.
Secondary audio
This is audio signals of comment of movie director
and other data recorded in the bonus view of
BD-Video.
Speaker impedance
This is an AC resistance value, indicated in Ω
(ohms). Greater power can be obtained with this
value smaller.
T
Title
This is the unit of content that consists of chapters
of Blu-ray Disc or DVD-Video. Some Blu-ray Disc or
DVD-Video may include multiple titles.
V
Virtual Package
For BD-Video discs compatible with Virtual Package,
contents are copied from the discs or internet to
local storage. It is automatically copied to the local
storage prior to playback. You can enjoy a variety
of additional functions including secondary video,
secondary audio, subtitles, movie trailer, etc.
• The playback methods vary depending on the
disc. (For details, refer to the disc manual.)
W
WMA (Windows Media Audio)
This is audio compression technology developed by
Microsoft Corporation.
WMA data can be encoded using Windows
Media® Player Ver.7, 7.1, Windows Media® Player
for Windows® XP and Windows Media® Player 9
Series.
To encode WMA files, only use applications
authorized by Microsoft Corporation. If you use
an unauthorized application, the file may not work
properly.
WMV (Windows Media Video)
A video format developed by Microsoft based on
the video compression standard MPEG-4.
This is one of the formats supported as standard by
Windows Media Player, the standard media player
in the Windows operating system.
It was designed based on the assumption of
network delivery, and has such features as a high
compression rate, support for streaming playback,
and support for DRM (Digital Rights Management
Technology) to control copying.
