AACS
“Advanced Access Content System” is a
specification 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.
BD-J application
The BD-ROM format supports Java for
interactive functions.
“BD-J” offers content providers almost
unlimited functionality when creating
interactive BD-ROM titles.
BD-R (page 86)
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 (page 86)
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-ROM (page 86)
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,
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/DVD players.
Blu-ray Disc (BD) (page 86)
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.
Deep Colour (page 68)
These are video signals for which the colour
depth of signals passing through an HDMI
jack have been enhanced. With a Non-Deep
Colour-compatible player, the number of
colours 1 pixel can express is 24 bits
(16,777,216 colours). However, with a Deep
Colour-compatible player, 1 pixel can
express more bits, such as 36 bits. With more
bits, the gradation of colour depth can be
expressed more finely, and continuous colour
changes will be displayed more smoothly.
Dolby Digital Plus (page 89)
Developed as an extension to Dolby Digital,
the audio coding technology supports 7.1
multi-channel surround sound.
Dolby TrueHD (page 89)
Dolby TrueHD is a lossless coding
technology 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-for-bit.
DTS (page 89)
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 High Resolution Audio (page 89)
Developed as an extension to DTS Digital
Surround format. It supports a maximum
sampling frequency of 96 kHz, and 7.1 multi-
channel surround.
DTS-HD High Resolution Audio has a
maximum transmission rate of 6 Mbps, with
lossy compression (Lossy).
