AACS
"Advanced Access Cotltetlt System" is a
specifcation for managing digital
entertainment contents stored on the next
generation of prerecorded and recorded
optical media. The specification enables
consumers to enjoy digital entertainment
content, including high-definition
content.
AVCHD(page 7)
The AVCHD fonnat is :t high definition
digital video camera format used to
record SD (standard defnition) or HD
(high definition) signals of either the
1080i specification *1 or the 720p
..... 9
specification _- 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.

BD-J application
The BD-ROM format supports Java I\_r
interactix, e functions.
"BD-J" offers content providers almost
unlimited fimctionality when creating
interactive BD-ROM titles.
BD-R (page 7)
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 calmot be overwritten, a
BD-R can be used to archive valuable
data or storing and distributing video
material.
BD-RE(page 7')
BD-RE (Bin-ray Disc Rewritable) is a
recordable and rewritable Bin-ray Disc,
available in the same capacities as the
BD below. The re-recordable feature
makes extensive editing and time-
shifting applications possible
BD-ROM(page 6)
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, metal operations
using pop-up menns (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, t_r playback on Blu-
ray Disc players.
Blu-rayDisc (BD) (page 6)
A disc format developed for recording/
playing lfigh-definition (HD) video (l\_r
HDTV, etc.), and for storing large
amounts of data. A single layer Bin-ray
Disc holds up to 25 GB, and a dual-layer
Blu-ray Disc holds up to 50 GB of data.
Chapter (page 26)
Sections of a picture or a nmsic feature
that are smaller than titles. A title is
composed of several chapters.
Depending on the disc, no chapters may
be recorded.
CPRM
"Content Protection for Recordable
Media" is a technology for protecting
digital entertainment content on
recordable media.
DolbyDigital (page 47)
Digital audio compression technology
developed by Dolby Laboratories. This
technology conforms to nmlti-channel
surround sound. The rear chalmel is
stereo and there is a discrete subwoofer
channel in this format. Dolby Digital
provides the same discrete channels of
high quality digital audio l\mnd 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.
DolbyDigital Plus (page 48)
Developed as an extension to Dolby
Digital, the audio coding teclmology
supports 7.1 multi-channel surround
sound. Since this player can convert
multi-channel surround sound signals to
5.1 channel, conventional AV amplifiers
(receivers) with a Dolby Digital decoder
can deliver the sound.
DolbySurround (Pro Logic)
(page 47)
Audio signal processing technology that
Dolby Laboratories developed for
surronnd sound. When the input signal
contains a surround component, the Pro
Logic process outputs the front, center
and rear signals. The rear channel is
monanral.
DolbyTrueHD (page 48)
Dolby TrueHD is a lossless coding
tectmology that supports up to 8
channels of multi-channel surround
sound for the next generation optical
discs. The reproduced sound is true to
the original source bit-l\)r-bit.
DTS (page 47)
Digital audio compression technology
that Digital Theater Systems, 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 47)
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 nmnber of discrete
surround sound channels. While 7.1ch
surround sound is planned for Bin-ray
Discs the audio signals can be
downmixed to 5.1 or 2 channels for
backward compatibility, and the
reproduced audio quality can either be at
the bit rate of DTS Digital Surround or
the lossless mode.
DVD VIDEO(page 6)
A disc format that contains up to eight
hours of moving pictures on a disc the
same diameter as a CD. A single-layer
single sided DVD holds up to 4.7 GB; a
double layer single-sided DVD, 8.5 GB;
a single layer double-sided DVD, 9.4
GB; double-layer double-sided DVD, 17
GB. The MPEG 2 format is adopted for
the efficient video data compression.
The variable rate coding technology that
changes the data to be allocated
according to the status of the picture is
adopted t_r reproducing high-quality
pictures. Audio information is recorded
in a multi-channel t_rmat, such as Dolby
Digital, allowing for a realistic audio
presence.
