ADSL
Abbreviation of Asymmetric
Digital Subscriber Line. ADSL is
one kind of broadband line. It relies
on the conventional copper wires
of telephone lines but supports
transmission of large amounts of
data by using the high-frequency
bandwidth separate from audio
signals. The upstream rate of
communication (for data sent
from the user's terminal) is slower
than the downstream rate (sent
from the provider to the user's
terminal), hence the description
"asymmetric". Transmission speeds
vary depending on the contracted
service.
ATRAC AD
Abbreviation for ATRAC Audio
Device. A general term for devices
that can play audio data in the
ATRAC format.
ATRAC3
One of the "ATRAC" audio
compression technologies
developed by Sony which
realizes high sound quality with
approximately 10 times the
compression rate of audio CDs.
ATRAC3plus
ATRAC3plus is an enhanced
version of ATRAC3. It realizes
20 times the compression ratio
of audio CDs, but with no loss in
sound quality.
Bit rate
The bit rate is a measure of data
volume expressed in bits per
second (bps).
1
GB
Broadband
General name for communication
lines that use a broad frequency
bandwidth for sending and
receiving large amounts of video
or audio data at high speed.
Currently, ADSL, CATV, FTTH
and other systems are identified as
broadband.
Broadband router
For Internet connections through
ADSL or a cable TV line, devices
called ADSL modems or cable
modems are used. However, for
Internet access from multiple
terminals connected at once, a
broadband router is used.
Byte
One of the fundamental units
used to express digitized data
in computers. Digitized data is
commonly expressed in binary
digits (zeros and ones). A single
unit of data is one bit. One byte
consists of eight bits.
CD TEXT
CD TEXT refers to an audio CD
with text information, including
disc name, artist names and track
names.
Condensation
Condensation occurs inside the
unit during where there is a quick
rise in temperature, as when a
heater is turned on. If condensation
occurs, keep the unit turned off
until the moisture evaporates.
DHCP
Abbreviation of Dynamic Host
Configuration Protocol. A system
for automatically allocating
configuration data required for an
Internet connection.
DLNA
Abbreviation of Digital Living
Network Alliance. The DLNA
is a nonprofit organization that
establishes design guidelines
for digital content shared over
networks.

DMPORT
DMPORT (DIGITAL MEDIA
PORT) allows the connection of a
DIGITAL MEDIA PORT adapter
which lets you directly connect and
listen to compatible digital media
players.
DNS
Abbreviation of Domain Name
System. A server that translates
domain names to IP addresses, or
IP addresses to domain names. A
DNS is identified by an IP address.
Also called a "DNS server".
Ethernet
A method of networking
computers in a Local Area Network
(LAN). Developed by Xerox
Corporation, Ethernet has become
a very popular means of creating
LANs.
Hard Disk
A high-volume, digitally encoded
storage device used in computers
and other digital devices. By
combining a magnetic disk and
drive mechanism into an integrated
unit, hard disks are capable of
very fast data writing and reading
and boast superb data search
capabilities.
