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.
NAT Network Address Translation is a system for forwarding data packets to different
private IP network addresses that reside behind a single public IP address.
NMOS Networked Media Open Specifications (NMOS) delivering Discovery and
Registration to ensure that parts of a networked media system can find each
other. NMOS also provides connection management and audio channel
mapping to device I/O channels.
Packet A formatted unit of data carried over packet-switched networks.
PAT Port Address Translation is 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
POTS Plain old telephone system: copper phone network infrastructure
Primary Leader
Clock The primary source of synchronization for clock distribution via PTP.
PSTN Public switched telephone network which is another term for POTS (see
previous)
PSU Power Supply Unit
PTP The general class clock distribution protocol standardized in IEEE 1588-2002,
IEEE 1588-2008 and IEEE 802.1AS-2011. PTP syncing requires a leader clock
source (often an installed PTP primary leader clocking device) with clocking
replicated on synced devices.
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 to use
over WANs.
RTP A standardized packet format using UDP/IP networking for sending audio and
video data streams and ensures consistency in the delivery order of voice data
packets.
RTP stream An RTP stream is a sequence of RTP packets with media data sent at regular
interval. A stream may contain multiple channels. There may be multiple media
streams per RTP session.
Runtime (edits) Configuration changes which have not yet been saved, e.g. Matrix Editor edits.
SAP SAP (Session Announcement Protocol) is used to distribute SDP descriptions
to receivers, enabling simplified connection management for multicast
streaming.
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 is a common protocol which works with a myriad of other protocols to
establish connections with other devices to provide interoperability
SIP URI A SIP URI is a URI used by SIP to identify user agents. SIP URI take the form
sip:<user>@<domain> or sips:<user>@<domain>.
SLA Service Level Agreements (SLAs) a contractual agreement between an ISP and
a customer defining expected performance levels over a network
SmartStream
PLUS Tieline implementation of redundant IP streaming.
SNMP Simple Network Management Protocol: Simple Network Management Protocol:
a protocol used mostly in network management systems to monitor devices for
conditions that warrant administrative attention.
