Video wall
A coordinated array of displays driven by a single processor so that any source can occupy any region of the combined canvas.
Leer → - N
NDI (Network Device Interface)
An IP-based protocol from NewTek/Vizrt for transporting low-latency, frame-accurate video and audio between devices on a standard Ethernet network.
Leer → - K
KVM (Keyboard, Video, Mouse) over IP
A switching technology that lets one operator console reach the keyboard, video, and mouse of remote machines over an IP network — central to modern control rooms.
Leer → - M
Multiviewer
A device or software that combines many video sources into a single composite output for monitoring on one screen — historically a broadcast tool, now common in NOCs and AV.
Leer → - N
NOC (Network Operations Center)
A facility where operators monitor and manage telecom networks, IT infrastructure, and connected services 24/7.
Leer → - S
SOC (Security Operations Center)
A facility focused on detecting, investigating, and responding to cybersecurity threats across an organisation in real time.
Leer → - S
Situation room (situation centre)
A purpose-built facility for cross-functional decision-making during emergencies or large-scale operations — the operational descendant of military command rooms.
Leer → - S
SCADA (Supervisory Control and Data Acquisition)
An industrial control architecture for monitoring and remotely commanding physical equipment — power grids, pipelines, water systems, manufacturing lines.
Leer → - A
AV over IP
The general practice of carrying audio and video signals over IP networks instead of dedicated cabling — the foundation of every modern control room and broadcast facility.
Leer → - V
Video wall controller
The hardware appliance or software platform that drives a video wall — composing sources, managing layouts, and surviving failures.
Leer → - I
IPMX
Open AV-over-IP standard built on SMPTE ST 2110 but adapted for ProAV: JPEG-XS compression, optional PTP, native HDCP, NMOS management.
Leer → - N
NMOS
Open suite of specifications for discovering and managing networked media devices: IS-04 for discovery, IS-05 for connection control.
Leer → - S
SMPTE ST 2110
Broadcast-grade family of standards for carrying uncompressed video, audio and ancillary data over IP networks, with PTP-locked timing.
Leer → - S
SDVoE
Software Defined Video over Ethernet — uncompressed AV-over-IP standard built around 10 GbE and the Aquantia / Marvell AQrate chipset.
Leer → - I
IP-KVM
Keyboard, video and mouse signals carried over an IP network instead of dedicated KVM cabling, letting any operator desk reach any source PC.
Leer → - E
Edge AI for video walls
On-prem machine-learning inference inside the video wall pipeline: anomaly detection, automatic source promotion, face / plate counting — without sending feeds to the cloud.
Leer → - W
WebGPU
Browser-native GPU API that replaces WebGL with Vulkan/Metal-class semantics: compute shaders, multi-threaded command encoding, two-orders-of-magnitude performance gain.
Leer → - M
MicroLED
Direct-view LED display technology with sub-millimetre pixel pitch, 96% BT.2020 colour gamut, ~100,000 hour lifetime — the successor to fine-pitch LCD for control-room walls.
Leer → - D
dvLED (direct-view LED)
Display technology where each pixel is a directly visible LED diode — no LCD layer, no projection. Encompasses fine-pitch LED video walls used in control rooms, broadcast studios, and high-end signage.
Leer → - N
NDI HX
High-efficiency NDI variant. Uses H.264 or H.265 compression instead of full NDI's lightly-compressed visually-lossless format — fits NDI signals onto low-bandwidth networks like Wi-Fi at the cost of slightly higher latency and CPU/GPU decode overhead.
Leer → - D
Dante AV
Audinate's AV-over-IP transport. Started as Dante audio (the dominant pro-audio networked-audio standard), extended to networked video. Competes with SDVoE for low-latency AV-over-IP at the operator-control tier.
Leer → - S
SRT (Secure Reliable Transport)
Open-source streaming protocol developed by Haivision. Delivers low-latency video over unpredictable public-internet links with packet-loss recovery and AES encryption — the standard for contribution feeds and remote-production backhaul.
Leer → - P
Pixel pitch
The centre-to-centre distance between adjacent pixels on a display, in millimetres — the single number that drives minimum viewing distance for a direct-view LED video wall.
Leer → - B
Bezel correction
The display-driver technique that hides the physical bezel between LCD panels in a video wall by offsetting the image so straight lines and moving objects appear continuous across the seam.
Leer → - P
PSIM (Physical Security Information Management)
Software that aggregates feeds from access control, intrusion detection, CCTV, alarms, and other physical-security subsystems into a single operational view for security operations centres.
Leer → - E
EOC (Emergency Operations Centre)
A facility from which multi-agency emergency response is coordinated during an activation — distinct from a NOC by being activation-driven, multi-agency, and command-and-control structured.
Leer → - P
PTP (Precision Time Protocol, IEEE 1588)
An IEEE-standardised network protocol that distributes a common clock across Ethernet endpoints to sub-microsecond accuracy — the timing backbone for uncompressed AV-over-IP standards like SMPTE ST 2110.
