Glossary
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.
ATRAC
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.
ATRACplus
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).
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.
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.
