3 Glossary of Terms
AES/EBU Digital audio standard used to carry digital audio signals between devices.
AES3 Official term for the audio standard referred to often as AES/EBU.
DNS The Domain Name System (DNS) is used to assign domain names to IP
addresses over the World-Wide Web.
DSCP The Differentiated Services Code Point is a field in an IP packet header for
prioritising data when traversing IP networks
Fail over Method of switching to an alternative audio stream if the primary connection is
lost.
GUI Acronym for Graphic User Interface
ISP Internet Service Providers (ISPs) are companies that offer customers access to
the internet
IP Internet Protocol; used for sending data across packet-switched networks.
LAN Local Area Network; a group of computers and associated devices sharing a
common communications link
Latency Delay associated with IP networks and caused by algorithmic, transport and
buffering delays.
Multicast Efficient one to many streaming of IP audio using multicast IP addressing.
Multi-unicast A multi-unicast program (also known as multiple unicast) can transmit a single
audio stream with common connection settings to a number of different
destinations.
Network Address
Translation
(NAT) A system for forwarding data packets to different private IP network addresses
that reside behind a single public IP address.
Packet A formatted unit of data carried over packet-switched networks.
Port Address
Translation
(PAT)
Related to NAT; a feature of a network device that allows IP packets to be
routed to specific ports of devices communicating between public and private IP
networks.
PSU Power Supply Unit
QoS (Quality of
Service) Priority given to different users or data flows across managed IP networks. This
generally requires a Service Level Agreement (SLA) with a Telco or ISP.
RTP A standardized packet format for sending audio and video data streams and
ensures consistency in the delivery order of voice data packets.
SDP SDP defines the type of audio coding used within an RTP media stream. It
works with a number of other protocols to establishes a device’s location,
determines its availability, negotiates call features and participants and adjusts
session management features.
SIP SIP works with a myriad of other protocols to establish connections with other
devices. It is used to find call participants and devices and is the method used
by most broadcast codecs to connect to competing brands of codec for
interoperability.
SLA Service Level Agreements (SLAs) a contractual agreement between an ISP and
a customer defining expected performance levels over a network
STL Studio to transmitter link for program audio feeds.
TCP TCP protocol ensures reliable in-order delivery of data packets between a
sender and a receiver. Its two functions include controlling the transmission
rate of data and ensuring reliable transmission occurs. Generally not well-
suited to streaming live audio because buffering (latency) is employed to
ensure data packets are received in order
TTL Time-to-Live is the setting used in multicast servers to ensure data packets
have a finite life and don't cause congestion over networks.
