Additional Information
surround sound is planned for Blu-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 11, 149)
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 for reproducing high-quality
pictures. Audio information is recorded
in a multi-channel format, such as Dolby
Digital, allowing for a realistic audio
presence.
DVD-R (page 11, 148)
A DVD-R is a recordable disc that is the
same size as a DVD VIDEO. Contents
can be recorded only once to a DVD-R,
and will have the same format as a DVD
VIDEO. The DVD-R has two different
modes: VR mode and Video mode.
DVDs created in Video mode have the
same format as a DVD VIDEO, while
discs created in VR (Video Recording)
mode allow the contents to be
programmed or edited.
DVD-RW (page 11, 148)
A DVD-RW is a recordable and
rewritable disc that is the same size as a
DVD VIDEO. The DVD-RW has two
different modes: VR mode and Video
mode. DVDs created in Video mode
have the same format as a DVD VIDEO,
while discs created in VR (Video
Recording) mode allow the contents to
be programmed or edited.
DVD+R (page 11, 148)
A DVD+R (read “plus R”) is a
recordable disc that is the same size as a
DVD VIDEO. Contents can be recorded
only once to a DVD+R, and will have the
same format as a DVD VIDEO.
DVD+RW (page 11, 148)
A DVD+RW (read “plus RW”) is a
recordable and rewritable disc.
DVD+RWs use a recording format that
is comparable to the DVD VIDEO
format.
Film-based software, Video-based
software (page 112)
DVDs can be classified as Film-based or
Video-based software. Film-based
DVDs contain the same images (24
frames per second) that are shown at
movie theaters. Video-based DVDs,
such as television dramas or sitcoms,
display images at 30 frames (or 60
fields) per second.
Frame (page 113)
Images that comprise moving pictures.
The moving pictures consist of 30
frames per second.
Hard disk drive (page 5, 11)
A hard disk drive is a whole mechanical
system that consists of disks and drive.
Disks are flat, circular, rigid plates
coated with a thin magnetic media.
Magnetic heads record data on the
rapidly spinning disks, and this enables
the speedy and efficient reading and
writing of data.
HDMI (High-Definition Multimedia
Interface) (page 23, 102, 105)
HDMI is an interface that supports both
video and audio on a single digital
connection. The HDMI connection
carries standard to high definition video
signals and multi-channel audio signals
to AV components such as HDMI
equipped TVs, in digital form without
degradation.
The HDMI specification supports HDCP
(High-bandwidth Digital Contents
Protection), a copy protection
technology for digital entertainment
contents for HDMI.
HDV (HDV format) (page 39)
A video format developed for DV
cassettes to record and play high-
definition pictures.
The server supports Interlace format
signals of 1080 effective scanning lines
(1080i).
When a compatible digital video camera
is connected, the server can record the
imported pictures on the HDD or a BD in
the original high-definition picture
quality.
Interlace format (page 101, 103)
Interlace format shows every other line
of an image as a single “field” and is the
standard method for displaying images
on television. The even number field
shows the even numbered lines of an
image, and the odd numbered field
shows the odd numbered lines of an
image.
IP Address (page 121)
Device ID information used according to
TCP/IP (Transmission Control Protocol/
Internet Protocol) on the network. IP
addresses are expressed as a sequence of
numbers in one to three digits separated
by dots (e.g., 192.168.0.2).
LPCM (Linear PCM) (page 52, 114)
A digital audio format that does not
cause deterioration in data compression
and expansion.
MAC Address (Media Access
Control Address) (page 117)
Unique numbers assigned to each LAN
terminal to identify devices connected to
the network.
You can check the server’s MAC
address in [Settings] – [Device
Information].
Metadata (page 137)
Content information that the AMG
database service provides in the Internet
(e.g., title names of music CDs and BD/
DVD movies). Metadata contains artist
names, genres, credits, copyright info,
product numbers, etc.
Modem (page 26)
Device used for Internet connection.
Modems are usually connected to a
router in a home environment. Either a
DSL Modem or a cable modem can be
used, depending on the line connecting
to the Internet service provider.
MPEG-2 (page 55)
One of the video data compression
schemes established by the Moving
Picture Experts Group (MPEG), which is
adopted for DVD VIDEOs and digital
broadcasts worldwide. The scheme
specifies MPEG-2 PS (Program Stream)
for recordable media such as a DVD
VIDEO, and MPEG-2 TS (Transport
Stream) for digital broadcasts and other
communications.
MP3 (page 52, 111)
An audio file format that compresses
PCM signals into 1/10 of its original
size.
Parental Control (page 118)
A function of BD-ROMs/DVD VIDEOs
to limit playback of the disc by the age of
the users according to the limitation level
in each country or area. The limitation
varies from disc to disc; when it is
activated, playback is completely
prohibited, violent scenes are skipped or
replaced with other scenes and so on.
PCM (page 114)
Pulse Code Modulation is one of the
methods for converting analog signals to
digital data. The analog signal is
sampled regularly at uniform intervals,
and then quantized to a series of symbols
in a digital code. The quality of data is
determined by the sampling frequency
per second, and the quantization bit rate.
