“Advanced Audio Coding” is a digital
audio codec adapted for digital
broadcast. It features a high compression
rate and high quality audio comparable
to music CDs.
ATRAC (page 52)
“ATRAC Advanced Lossless” is a
lossless audio compression technology
that compresses and expands CD audio
data completely, thus reproducing the
original CD quality audio.
ATSC (page 56)
A technical standard for digital
broadcasts in the U.S. The specification
adapts MPEG-2 for video compression,
and AC-3 for audio compression.
The AVCHD format is a high definition
digital video camera format used to
record SD (standard definition) or HD
(high definition) signals of either the
1080i specification*
1
or the 720p
specification*
2
on DVDs, using efficient
data compression coding technology.
The MPEG-4 AVC/H.264 format is
adopted to compress video data, and the
Dolby Digital or Linear PCM is used to
compress audio data. The MPEG-4
AVC/H.264 format is capable of
compressing images at higher efficiency
than that of the conventional image
compression format. The MPEG-4
AVC/ H.264 format enables a high
definition (HD) video signal shot on a
digital video camera recorder to be
recorded on DVDs in the same way as
for a standard definition (SD) television
signal.
*
1
A high definition specification that
utilizes1080 effective scanning lines and
the interlace format.
*
2
A high definition specification that utilizes
720 effective scanning lines and the
progressive format.
BD-R (Blu-ray Disc Recordable) is a
recordable, write-once Blu-ray Disc,
available in the same capacities as the
BD below. Since contents can be
recorded and cannot be overwritten, a
BD-R can be used to archive valuable
data or storing and distributing video
material.
BD-RE (Blu-ray Disc Rewritable) is a
recordable and rewritable Blu-ray Disc,
available in the same capacities as the
BD below. The re-recordable feature
makes extensive editing and time-
shifting applications possible.
BD-ROMs (Blu-ray Disc Read-Only
Memory) are commercially produced
discs and are available in the same
capacities as the BD below. Other than
conventional movie and video contents,
these discs have enhanced features such
as interactive content, menu operations
using pop-up menus (see below),
selection of subtitle display, and
slideshow. Although a BD-ROM may
contain any form of data, most BD ROM
discs will contain movies in High
Definition format, for playback on Blu-
ray Disc players.
Blu-ray Disc (BD) (page 11)
A disc format developed for recording/
playing high-definition (HD) video (for
HDTV, etc.), and for storing large
amounts of data. A single layer Blu-ray
Disc holds up to 25 GB, and a dual-layer
Blu-ray Disc holds up to 50 GB of data.
Sections of a picture or a music feature
that are smaller than titles. A title is
composed of several chapters.
Depending on the disc, no chapters may
be recorded.
Copy protection signals (page 98)
Copy restriction set by copyright
owners, etc.
These signals are included in some
software or TV programs and restrict
recording.
The artwork displayed on the front cover
of pre-recorded CD, DVD, and Blu-Ray
discs.
CPRM (page 98)
“Content Protection for Recordable
Media” is a technology for protecting
digital entertainment content on
recordable media.
Downmix (page 119)
A process in which surround sounds are
converted to have fewer channels than
the original source.
DHCP (Dynamic Host Configuration
Protocol) (page 121)
A set of rules to automatically assign
settings necessary for network
communication.
Usually the router or the Internet service
provider’s server functions as the DHCP
server.
DLNA (Digital Living Network
Alliance) (page 74)
An association that formulates audio/
photo/video distribution among PCs and
other digital devices in a home network
environment, or the format itself.
DLNA certified devices are
interoperable with each other, thus
making them easy to communicate on
the network.
Dolby Digital (page 114)
Digital audio compression technology
developed by Dolby Laboratories. This
technology conforms to multi-channel
surround sound. The rear channel is
stereo and there is a discrete subwoofer
channel in this format. Dolby Digital
provides the same discrete channels of
high quality digital audio found in
“Dolby Digital” theater surround sound
systems. Good channel separation is
realized because all of the channel data is
recorded discretely and little
deterioration occurs because all channel
data processing is digital.
Dolby Surround (Pro Logic)
(page 119)
Audio signal processing technology that
Dolby Laboratories developed for
surround sound. When the input signal
contains a surround component, the Pro
Logic process outputs the front, center
and rear signals. The rear channel is
monaural.
DRM (Digital Rights Management)
(page 53)
Technologies for protecting the
copyright of digital content, mainly by
limiting its usages and copying.
DTS (page 114)
Digital audio compression technology
that DTS, Inc. developed. This
technology conforms to multi-channel
surround sound. The rear channel is
stereo and there is a discrete subwoofer
channel in this format. DTS provides the
same discrete channels of high quality
digital audio.
Good channel separation is realized
because all of the channel data is
recorded discretely and little
deterioration occurs because all channel
data processing is digital.
DTS-HD (page 59)
DTS-HD is an extended format of the
Coherent Acoustics audio coding
system, which also encompasses DTS
Digital Surround, DTS-ES, and DTS 96/
24. DTS-HD is highly flexible in
supporting the number of discrete
surround sound channels. While 7.1ch
