IP Routing Terminology
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.
SMPTE 2110 A standard for an extensible RTP IP streams (essence streams,
including uncompressed video) referenced to a common clock.
Includes support for a variable raster size (up to 32Kx32K pixels), HDR,
and a variety of color sampling schemes, bit depths and frame-rates.
Source Originator of one or more flows. Source spigot.
Spigot A generic term for a source or a destination of one or more flows.
Stream Term usually associated with delivery of constant, real-time media
(e.g. Audio, Video) over IP networks with a stream of data packets.
TR-03 A Video Services Forum (VSF) Technical Recommendation concerning
the transport of time-related uncompressed media over IP.
Carriage of video, audio and ancillary data in separate elementary
streams to provide greater flexibility in the production of media.
TR-04 A Video Services Forum (VSF) Technical Recommendation concerning
the transport of media streams and elementary streams over a
network.
