GLOSSARY OF TERMS

AAC - • Advanced Audio Coding. This is a standardised encoding system for

digital audio. Designed to be the successor of the MP3 format, AAC generally

achieves better sound quality than MP3.

AAC’s best known use is as the default audio format of Apple’s iPhone, iPod,

iTunes, and the format used for all iTunes Store audio.

DAB - • Digital Audio Broadcasting. This is a digital radio technology for

broadcasting radio stations, used in several countries, particularly in the UK and

Europe. As of 2006, approximately 1,000 stations worldwide broadcast in the

DAB format.

The standard offers several beneﬁts over existing analogue FM radio, such as

more stations in the same broadcast spectrum, and increased resistance to

noise, multipath, fading, and co-channel interference.

DHCP - • Dynamic Host Conﬁguration Protocol (DHCP) is a network application

protocol used by devices to obtain conﬁguration information for operation in

an Internet Protocol network. This protocol reduces system administration

workload, allowing devices to be added to the network with little or no manual

intervention.

Dynamic Host Conﬁguration Protocol automates network parameter assignment

to network devices from one or multiple, fault-tolerant DHCP servers. Even in

small networks, DHCP is useful because it can make it easy to add new machines

to the network.

EQ - • Equaliser. This is used to change the characteristics of the sound output by

the AirStream10. The changes can included accentuated bass, treble or voices.

These are all preset curves that cannot be altered.

Frontier Silicon - • Established in 2001 as a privately-funded fabless semiconductor

company, Frontier Silicon has rapidly become the world’s leading supplier of

innovative semiconductor, module and software solutions for digital radio and

connected audio systems.

Headquartered in Watford, on the northwest outskirts of London, Frontier Silicon

has around 120 staff, 70% engineers, with R&D centres in several locations

including Cambridge, Dublin, Shannon and Hong Kong

Their multimode connected audio platforms support over 10,000 Internet radio

stations through the Frontier Silicon on-line radio portal. Innovative on-line music

services are driving forward our platforms to support more sophisticated displays

and graphical user interfaces as we move from mono to rich full colour UI’s.

IP Address - • An Internet Protocol address is a numerical identiﬁcation that is

assigned to devices participating in a computer network utilising the Internet

Protocol for communication between its nodes. Although IP addresses are stored

as binary numbers, they are usually displayed in human-readable notations, such

as 192.168.68.1

The original designers of TCP/IP deﬁned an IP address as a 32-bit number and

this system, is still in use today.

Media Streaming - • Streaming media is media that is constantly transferred

between devices contained on a network.

MP3 - • MP3, is a digital audio encoding format using a form of lossy data

compression. It is a common audio format for consumer audio storage, as well

as a de facto standard encoding for the transfer and playback of music on digital

audio players.

Podcast - • A podcast is a series of audio or video digital media ﬁles which are

distributed over the Internet, through web feeds, to portable media players and

personal computers. Though the same content may also be made available by

direct download or streaming, a podcast is distinguished from most other digital

media formats by its ability to be syndicated, subscribed to, and downloaded

automatically when new content is added. Like the term broadcast, podcast

can refer either to the series of content itself or to the method by which it is

syndicated; the latter is also called podcasting.

RDS - • Radio Data System, is a communications protocol standard from the

European Broadcasting Union for sending small amounts of digital information

using conventional FM radio broadcasts. The RDS system standardises several

types of information transmitted, including time, track/artist info and station

identiﬁcation. RDS has been standard in Europe and Latin America since the

early 1990s, but less so in North America.

Radio Broadcast Data System is the ofﬁcial name used for the U.S. version of

RDS, though the “RDS” name seems to be at least as common in usage. The

two standards are nearly identical, with only slight differences, mainly in which

numbers are assigned to each of 31 musical and other program formats the

RBDS system can identify. RBDS was approved by the NRSC, RDS by the

EBU.
