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.

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.
