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 is a system for forwarding data packets to different
private IP network addresses that reside behind a single public IP address.
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.
A formatted unit of data carried over packet-switched networks.
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
Plain old telephone system: copper phone network infrastructure
The primary source of synchronization for clock distribution via PTP.
Public switched telephone network which is another term for POTS (see
previous)
Power Supply Unit
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.
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.
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.
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.
Configuration changes which have not yet been saved, e.g. Matrix Editor edits.
SAP (Session Announcement Protocol) is used to distribute SDP descriptions
to receivers, enabling simplified connection management for multicast
streaming.
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 is a common protocol which works with a myriad of other protocols to
establish connections with other devices to provide interoperability
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>.
Service Level Agreements (SLAs) a contractual agreement between an ISP and
a customer defining expected performance levels over a network
Tieline implementation of redundant IP streaming.
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.
