Glossary
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 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.
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.
ID3
ID3 is information (such as the
track name or artist name) that is
recorded in an MP3 file. The ID3 tag
is used by this unit to display track
information for MP3 files.
ISO9660
A standard of the International
Organization for Standardization
(ISO) that defines the file system of
CD-ROM media.
MP3
Abbreviation of 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.
Sampling frequency
When audio sources are converted
from analog to digital data, they
must be changed into numbers
(digitized). This process is called
sampling, and the sampling
frequency refers to the number of
times per second that the signals are
measured for the recording.
Music CDs are sampled at 44,100
times per second, so the sampling
frequency is expressed as 44.1 kHz.
Generally, the higher the sampling
frequency, the higher the fidelity of
the recording.
WMA
Abbreviation of Windows Media
Audio. WMA is the audio
compression technology developed
by Microsoft Corporation that allows
audio files to be compressed to about
1/22 of the data size of a standard
compact disc.
WM-PORT
A port designated for connecting a
“WALKMAN”.
DAB (Digital Audio
Broadcasting)-related
terms (UK model only)
Dynamic label segment
The text data transmitted for each
channel or service.
Ensemble label
In DAB, multiple digital radio
channels are transmitted using
a single radio transmission or
frequency. A group of channels sent
this way is called an “ensemble” and
“ensemble label” is the name of such
a group.
Service label
The name of an individual digital
radio channel or service.
