IPRC
IP Router Controller, a functional block within an IP-RSC.
The IPRC presents the IP routing system as a traditional video router to
the outside world.
LLDP
Local Link Discovery Protocol:
An open IP protocol used to advertise an edge device’s identity,
capabilities, and other connected devices within the same IP network.
Media network
A high-capacity network dedicated to carrying high bit rate media.
Multicast Stream
A one-to-many IP stream. Devices receiving the stream subscribe to
the multicast stream’s IP address.
Network
A group of two or more ethernet-enabled systems linked together via IP.
In the case of broadcast video IP network, a local area network
optimized for the transfer and broadcast of real-time, high bandwidth
video IP streams
Northbound
Describes Control network data packet traffic.
Out-of-Band
Control
Method of sending control messages for an IP routing system in a
separate control network.
RFC-4175
TR-03 uses Internet Engineering Task Force’s (IETF) RFC-4175 to
pack (uncompressed) active video lines into an RTP IP stream.
RollCall
SAM control and monitoring system.
RollCallv3
Traditional SAM RollCall messages in the SAM RollCall control and
monitoring system product.
R
New extension to SAM RollCall.
Uses R Domains to separate data flow types.
Used in MV-8 series Multiviewers and in IP Routing control and
configuration.
RTP
Real-time Transport Protocol.
An IP standard which specifies a way to manage the real-time
transmission of multimedia data over a network.
SDI
Serial Digital Interface.
A method for packing real-time media (uncompressed video, audio and
metadata essences) into a digital serial bit stream and sending it over a
low-latency, point-to-point electrical link (typically a coaxial cable).
SMPTE 2022-6
A transport protocol for the real time transport of high bit-rate
video/audio data over IP networks, where the entire payload of the SDI
signal is encapsulated as one IP stream.
Designed to be applied to television transport for broadcast production
and is not intended for emission purposes.
SMPTE 2022-7
A standard for the seamless reconstruction of a stream from the
transmission of two streams of identical content over potentially diverse
paths.
Enables cost-effective redundant network operation. Two network are
used and a full stream is sent on each network. A receiving device can
switch between two received streams and recover the content of the
original full stream.
