AVCHD
AVCHD
is
a new format (standard) for high definition video cameras
that can
be
used
to
record and play high-resolution
HD
images.
BD-J
Some BD-Video discs contain Java applications, and these
applications are called BD-J.
You
can
enjoy various interactive
features
in
addition
to
playing normal video.
BD-Live
This
is
aBO-Video (BD-ROM Profile
2)
that supports the new
functions such as Internet connection, etc.
in
addition
to
the
BONUSVIEW function
Bitstream
This
is
the digital form of multi-channel audio data (e.g.,
5.1
channel)
before
it
is
decoded into its various channels.
BONUSVIEW (Final Standard Profile)
This
is
aBO-Video (BD-ROM Profile 1 version 1.1) that supports the
new functions such as Picture-in-picture, Secondary Audio, etc.
Deep
Color
Deep Color
is
a name for device that can reproduce greater color
gradation (4096 steps) when connected
to
a TV that supports the
Deep Color with HDMI cable.
You
can enjoy exceptionally rich,
natural-looking colors, with smooth, detailed gradation and minimal
color banding. [A lower color gradation (256 steps), without Deep
Color, will be reproduced if connected
to
a TV which does not support
Deep Color. The unit will automatically set appropriate output
to
suit
the connected
TV]
DivX
Ls1Ilio
DivX
is
a popular media technology created
by
DivX, Inc. DivX media
files contain highly compressed video with high visual quality that
maintains a relatively small file size.
DNS Server
A server which acts like a telephone directory and translates Internet
domain names into IP addresses.
Dolby
Digital
This
is
a method of coding digital signals developed
by
Dolby
Laboratories. Apart from stereo (2-channel) audio, these signals can
also be multi-channel audio.
Dolby
Digital
Plus
Multi-channel audio and higher audio quality
is
made possible using
Dolby Digital Plus. BD-Video supports up
to
7.1
channel output.
Dolby
TrueHD
Dolby TrueHD
is
a very high quality audio format that reproduces the
studio master audio. BD-Video supports up
to
7.1
channel output.
Down-mixing
This
is
the process of remixing the multi-channel audio found
on
some discs into fewer channels.
DTS (Digital Theater
Systems)
This surround system
is
used
in
many movie theaters. There
is
good
separation between the channels. so realistic sound effects are
possible.
DTS-HD
DTS-HD
is
a high-quality, sophisticated audio format used
in
movie
theaters. Previous DTS Digital Surround-compatible equipment can
play DTS-HD as DTS Digital Surround audio. BD-Video supports
up
to
7.1
channel output.
DTS-HD High
Resolution
Audio
This
is
a signal format achieved
by
improving the previous DTS,
DTS-ES and DTS96/24 formats.
It
is compatible with sampling
frequency 96 kHz/48 kHz. BD-Video supports
up
to
7.1
channel
output.
DTS-HD
Master
Audio
This
is
a lossless audio format and compatible with 96 kHz/7.1ch or
less.
In
addition, faithful reproduction of the master audio is enabled
using lossless audio encoding technology. BD-Video supports
up
to
7.1
channel output.
Dynamic
range
Dynamic range
is
the difference between the lowest level of sound
that can
be
heard above the noise of the equipment and the highest
level of sound before distortion occurs.
Dynamic range compression means reducing the gap between the
loudest and softest sounds. This means you can listen at low
volumes but still hear dialog clearly.
Film and
video
DVD-Video are recorded using either film or video. This unit can
determine which type has been used, then uses the most suitable
method of progressive output.
Film: Recorded at
24
frames per second. (Recorded at 30
frames per second as well). Generally appropriate for
motion picture films.
Video: Recorded at
30
frames/60 fields per second. Generally
appropriate for TV drama programs or animation.
Frames and
fields
Frames refer
to
the single images that constitute the video you see
on
your television. Each frame consists of two fields.
Frame Field Field
eA
frame still shows two fields,
so
there may
be
some blurring, but
picture quality is generally better.
eA
field still shows less picture information
so
it
may
be
rougher, but
there
is
no blurring.
Gateway
IP
address of the electronic device providing Internet access.
Usually called a router
IP
address. (e.g., 192.168.0.1)
HDMI (High-Definition
Multimedia
Interface)
HDMI
is
a digital interface for consumer electronic products. Unlike
conventional connections, it transmits uncompressed digital video
and audio signals
on
a single cable.
Hub
Used for connecting more than one device
to
the network.
IP address
A set of numbers which distinguish each device
on
the network when,
for example, connected
to
the Internet. When using a
PC
in
a LAN
to
access a
PC
or device that is not included
in
the LAN, the IP address
is
called the 10cailP address. (e.g., 192.168.0.10)
JPEG
(Joint
Photographic
Experts
Group)
This
is
a system used for compressing/decoding color still pictures. If
you select JPEG
as
the storage system
on
digital cameras, etc., the
data will be compressed
to
1/10-1/100 of
its
original size. The benefit
of JPEG
is
less deterioration
in
picture quality considering the degree
of compression.
LAN (Local Area
Network)
A group of linked devices
in
a company, school or home.
Indicates the boundaries of a particular network.
Local storage
This storage area
is
used as a destination for sub contents for playing
BD-Live
on
BD-Video.
LPCM
(Linear
PCM)
These are a kind of PCM format.
These are uncompressed digital signals, similar
to
those found
on
CDs.
MPEG2 (Moving
Picture
Experts Group)
A standard for efficiently compressing and expanding color video.
MPEG2
is
a compression standard used for
DVD
and satellite based
digital broadcasting.
MP3 (MPEG
Audio
Layer
3)
An
audio compression method that compresses audio
to
approximately one tenth of its size without any significant loss of
audio quality.
