AAC
Abbreviation for Advanced Audio
Coding. It is a standard for audio file
compression determined by the
MPEG (Motion Picture Experts
Group), an ISO (International
Organization for Standardization)/
IEC (International Electrotechnical
Commission) working group.
Bit rate
The bit rate is a measure of data
volume expressed in bits per second
(bps).
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.
Condensation
Condensation can occur in the unit
when there is a rapid rise in
temperature, as when a heater is
turned on. If condensation occurs,
keep the unit turned off until the
moisture evaporates.
DHCP
Abbreviation for Dynamic Host
Configuration Protocol. A system for
automatically allocating
configuration data required for an
Internet connection.
DLNA
Abbreviation for Digital Living
Network Alliance. The DLNA is a
nonprofit organization that
establishes design guidelines for
digital content shared over networks.

DNS
Abbreviation for 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."
HE-AAC
Abbreviation for High-Efficiency
Advanced Audio Coding. Compare
to AAC, it realizes high sound
quality with low bit rate.
Internet Service Provider
A company that offers a connection
service to the Internet.
IP address
IP addresses usually consist of four
groups of up to three digits each,
separated by a period (such as
192.168.239.1). All devices on a
network must have an IP address.
LAN
Abbreviation for Local Area
Network.
LAN is a general name for networks
set up for communication among
devices including computers,
printers, and fax machines in
relatively small areas such as offices
or buildings.
MAC address
Abbreviation for Media Access
Control address. It is an
identification name assigned to all
network devices. Each device has its
own address and there are no
duplicate addresses. A MAC address
may be necessary when identifying
the unit separately from other
devices (such as a DLNA server).
MP3
Abbreviation for MPEG-1 Audio
Layer3. It is a standard for audio file
compression determined by the
MPEG (Motion Picture Experts
Group), an ISO (International
Organization for Standardization)
working group. It enables
compression of audio files to about
1/10 of the data size of a standard
compact disc. Since the MP3
encoding algorithm is disclosed,
there are various encoders/decoders
that are compliant with this standard.
The MP3 standard is therefore
widely used in the computer field.
Network key (security key)
An encryption key used to limit the
devices with which communication
can occur. It is used to provide
higher security for devices
communicating via a wireless LAN
router/access point.
Proxy
A program or a server that provides
Internet access to computers within a
firewall or quicker downloading of
web pages.
Router
A device that bridges networks,
converting the protocols and
addresses of each network. When
connecting multiple network devices
to the Internet, a router is necessary.
The term "router" by itself may refer
to any of these devices.
SSID
Abbreviation for Service Set
IDentifier. It is a name that identifies
a particular access point within an
IEEE 802.11 wireless LAN. To
connect with an access point, a client
device must be set with the same
SSID. SSIDs can be up to 32
characters long. For higher security,
a network key is normally also used.
In this case, connection cannot occur
unless the SSID matches the network
key.
