Analog audio
An electrical signal that directly represents sound. Compare this to
digital audio which can also be an electrical signal, but is an indirect
representation of sound. See also
Digital audio
.
Aspect ratio
The width of a TV screen relative to its height. Conventional TVs are
4:3 (in other words, the screen is almost square); widescreen
models are 16:9 (the screen is almost twice as wide as it is high).
BD-J
BD-J is the Java specification for BD-ROM, allowing content
providers to put interactive material linked to specific titles on the
disc.
BDAV
BDAV is one of the application formats used by writable Blu-ray
Discs (BD-R or BD-RE). It corresponds to the VR mode of the DVD
standard.
BDMV
BDMV is one of the Blu-ray Disc standards (application standard for
BD-ROM). It corresponds to the Video mode of the DVD standard.
Default Gateway
Default Gateway is a node on a computer network that serves as an
access point to another network. A default gateway (such as a
computer and router) is used to forward all traffic that is not
addressed to a station within the local subnet.
DHCP (Dynamic Host Configuration Protocol) Server
A DHCP server is a server that allocates IP addresses to hosts
(network devices). In most cases, a broadband router serves as a
DHCP server in a home network.
Digital audio
An indirect representation of sound by numbers. During recording,
the sound is measured at discrete intervals by an analog-to-digital
converter, generating a stream of numbers. On playback, a
digital-to-analog converter generates an analog signal based on
these numbers. See also
Sampling frequency

Dolby Digital Plus
Dolby Digital Plus is the next-generation audio technology for all
high-definition programming and media. It combines the efficiency
to meet future broadcast demands with the power and flexibility to
realize the full audio potential expected in the upcoming high-
definition era. Built on Dolby Digital, the multi-channel audio
standard for BD and DVD, Dolby Digital Plus has been designed for
the next-generation AV Systems (amplifier or AV receiver) but
remains fully compatible with all current AV Systems.
Dolby Digital Plus delivers multi-channel audio programs of up to
7.1 channels and supports multiple programs in a single encoded
bitstream with the maximum bit rate potential of 6 Mbps and the
maximum bit rate performance of 1.7 Mbps on BD, and it outputs
Dolby Digital bitstreams for playback on existing Dolby Digital
systems. Dolby Digital Plus can accurately reproduce the sound
originally intended by directors and producers.
It also features multi-channel sound with discrete channel output,
interactive mixing and streaming capability in advanced systems.
Supported by HDMI (High-Definition Multimedia Interface), a single-
cable digital connection is possible for high-definition audio and
video.
Dolby TrueHD
Dolby TrueHD is the next-generation lossless encoding technology
developed for high-definition optical discs in the upcoming era.
Dolby TrueHD delivers tantalizing sound that is bit-for-bit identical to
the studio master, unlocking the true high-definition entertainment
experience on high-definition optical discs in the next generation.
When coupled with high-definition video, Dolby TrueHD offers an
unprecedented home theater experience with stunning sound and
high-definition picture.
It supports bit rates of up to 18 Mbps and records up to 8 full-range
channels individually with 24-bit/96 kHz audio. It also features
extensive metadata including dialogue normalization and dynamic
range control. Supported by HDMI (High-Definition Multimedia
Interface), a single-cable digital connection is possible for high-
definition audio and video. BD standards currently limit their
maximum number of audio channels to eight, whereas Dolby Digital
Plus and Dolby TrueHD support more than eight audio channels.
DRM (Digital Rights Management)
DRM is one of several technologies that controls access to and use
of digital data, such as music, movies and other copyrighted
contents.
On hybrid discs with BD and CD layers,
the CD layer cannot be played back.
• Change the
Set hybrid disc playback layer
to
CD
(page 43).
When the
Set hybrid disc playback layer
is set to
DVD
and you insert a hybrid disc
with BD and CD layers, the BD layer is
played back.
• When the layer set to playback at S
et hybrid disc playback layer
is not present on an inserted hybrid
disc, the BD layer is played back.
The
Set hybrid disc playback layer
setting cannot be changed (it is grayed
out).
• You cannot change the
Set hybrid disc playback layer
when a disc is inserted. Eject the disc to
make changes.
A ‘
’ appears in the file name.
• A character that cannot be displayed on this unit is included in the file name. Use only
alphanumeric characters if you want file names to be displayed correctly on this player.
The power automatically turns on.
• This unit’s power may be turned on when you control this unit from a connected plasma
display
. If
you do not want this unit to be turned on in this way, set this unit’s
HDMI Control
to
Off
(page 43).
