AEC — Acoustic Echo Cancellation
DSP algorithm that removes room reflections and far-end voice echo from microphone signals to enable full-duplex conferencing.
Beamforming — Steered Microphone Arrays
Beamforming uses an array of microphone capsules with DSP spatial filtering to steer a directional pickup pattern toward active speakers, rejecting off-axis noise — the technology behind MXA, Parlé, TeamConnect, and Stem ceiling microphones.
BYOD — Bring Your Own Device
Supporting personal laptops, tablets, and phones to connect to room AV systems for presentation and conferencing without fixed infrastructure endpoints.
BYOM — Bring Your Own Meeting
BYOM allows a room's AV infrastructure (camera, microphone, speakers, display) to be used by a video conference running on the user's personal laptop, bridging the gap between dedicated room codecs and unmanaged BYOD rooms.
Codec — Compression/Decompression
A codec encodes and decodes audio or video signals using compression algorithms — understanding codecs determines the quality, latency, and bandwidth trade-offs in video conferencing, AV-over-IP, and streaming systems.
DSP — Digital Signal Processing
Real-time digital manipulation of audio signals using algorithms running on dedicated processor hardware, enabling mixing, routing, EQ, dynamics, and conferencing functions in AV systems.
Latency and Jitter — AV Network Timing
Latency is the delay from source to destination; jitter is the variation in that delay — both critically affect live audio, video conferencing, and AV-over-IP systems.
LPCM — Linear Pulse Code Modulation and Audio Formats
LPCM is the uncompressed digital audio standard carried over HDMI and AES3 — understanding LPCM vs. compressed formats (Dolby Digital, DTS, Atmos) determines what a system can de-embed, process, and distribute.
MTR — Meeting Transformation Room
Premium hybrid collaboration spaces with certified hardware, AI-driven audio/video, and deep UCC platform integration for Teams, Zoom, and Webex.
PTZ — Pan/Tilt/Zoom Camera
Motorized camera with independent pan, tilt, and optical zoom motors for remote framing control in conference rooms, lecture halls, and broadcast studios.
SIP — Session Initiation Protocol
SIP is the signaling protocol for VoIP and video conferencing — understanding SIP is essential for integrating telephone interfaces, paging systems, and SIP-based video conferencing endpoints with AV systems.
STI — Speech Transmission Index
STI is the standard objective measure of speech intelligibility in a room — a value from 0 to 1 that predicts how clearly spoken words will be understood by listeners, accounting for reverberation, noise, and system distortion.
UCC — Unified Communications and Collaboration
Integrated platforms combining video conferencing, voice, messaging, and content sharing for seamless hybrid communication — Teams, Zoom, Webex, and Google Meet.
VISCA — Video System Control Architecture
VISCA is the dominant PTZ camera control protocol — a binary command set sent over RS-232 or UDP/TCP that commands pan, tilt, zoom, focus, iris, and preset recall on virtually every professional PTZ camera.
