Reference glossary of video-wall, control-room, and ProAV terminology — what each term means, how it relates to a software video wall, and where to read more.
- Video wall — A coordinated array of displays driven by a single processor so that any source can occupy any region of the combined canvas.
- 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.
- 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.
- 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.
- NOC (Network Operations Center) — A facility where operators monitor and manage telecom networks, IT infrastructure, and connected services 24/7.
- SOC (Security Operations Center) — A facility focused on detecting, investigating, and responding to cybersecurity threats across an organisation in real time.
- 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.
- SCADA (Supervisory Control and Data Acquisition) — An industrial control architecture for monitoring and remotely commanding physical equipment — power grids, pipelines, water systems, manufacturing lines.
- 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.
- Video wall controller — The hardware appliance or software platform that drives a video wall — composing sources, managing layouts, and surviving failures.
