Bit rate
e 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 o
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 le. e ID3
tag is used by this unit to display
track information for MP3 les.
ISO9660
A standard of the International
Organization for Standardization
(ISO) that denes the le system of
CD-ROM media.
MP3
Abbreviation of MPEG-1 Audio
Layer3. It is a standard for audio
le compression determined by the
MPEG (Motion Picture Experts
Group), an ISO (International
Organization for Standardization)
working group. It enables
compression of audio les 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. e MP3 standard
is therefore widely used in the
computer eld.
Sampling frequency
When audio sources are converted
from analog to digital data, they
must be changed into numbers
(digitized). is 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 delity of
the recording.
DAB (Digital Audio
Broadcasting)-related
terms (UK model only)
Dynamic label segment
e 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
e name of an individual digital
radio channel or service.
