Aspect Ratios
Understanding video aspect ratios, letterboxing, pillarboxing, and conversion issues in AV systems.
Digital Signage and CMS
Digital signage system architecture, media player hardware tiers, CMS platform comparison, content strategy, network requirements, and emergency override integration for commercial AV installations.
dvLED — Direct-View LED Displays
Direct-view LED (dvLED) display technology where each pixel is an individual LED, delivering seamless, high-brightness video walls for boardrooms, lobbies, broadcast studios, and outdoor signage.
EDID Management
EDID (Extended Display Identification Data) governs source output resolution and audio format — misconfigured EDID is the leading cause of black screens, wrong resolutions, and audio failures in HDMI systems.
Flat-Panel Displays — Commercial vs. Consumer, LCD, OLED, and LED
Selecting, specifying, and installing flat-panel displays for AV — commercial vs. consumer tiers, LCD/OLED/direct-view LED technologies, brightness, viewing angles, and control integration.
HDBaseT
Extended-distance HDMI transmission standard using Category 5e/6 cabling — architecture, specifications, versions, and comparison with proprietary alternatives.
HDCP — High-bandwidth Digital Content Protection
HDCP authenticates every link in an HDMI or DisplayPort signal chain to prevent unauthorized copying — understanding its version requirements, repeater chain limits, and failure modes is essential for reliable 4K AV system design.
HDMI vs DisplayPort
Comparison of HDMI and DisplayPort protocols for AV applications, including version history, bandwidth, compatibility, audio, and use cases.
LED Wall Sizing and Viewing Distance
Engineering formulas and practical guidelines for sizing direct-view LED walls — pixel pitch selection, minimum and maximum viewing distances, screen dimensions for content type, and room geometry calculations.
Projection Basics
Projector light engine technologies, laser vs. lamp, interchangeable lenses, throw ratio math, screen selection, brightness requirements, stacking, and product tier guidance for commercial AV installations.
PTZ Cameras — Selection, Mounting, and Control
PTZ (Pan-Tilt-Zoom) cameras are the primary video capture device in AV conferencing systems — selection, mounting position, control protocols (VISCA, ONVIF, NDI), and platform comparisons for installed AV.
UC Platforms — Microsoft Teams Rooms and Zoom Rooms
Certified hardware selection, compute options, licensing, room configuration, and interoperability for Microsoft Teams Rooms and Zoom Rooms deployments in commercial AV integration.
Video Conferencing Room Design
Comprehensive guide to designing effective video conferencing spaces covering display sizing, camera placement, microphone coverage, acoustic requirements, and network infrastructure.
Video Resolution Standards
Overview of video resolution standards from SD through 8K, including aspect ratios, frame rates, and practical AV requirements.
Video Switching and Matrix Routing
Comprehensive guide to AV matrix switchers, presentation switchers, auto-switching, and signal routing — the backbone of nearly every installed AV system.
Video Switching vs. Routing
Differences between video switching and routing architectures, including matrices, scalers, and signal management strategies.
Video Walls
Multi-display arrays using tiled LCD panels, rear-projection cubes, or direct-view LED for large-format, seamless visual presentations in control rooms, lobbies, and collaboration spaces.
Wireless Presentation Systems
Comparison and configuration of wireless content sharing platforms — Crestron AirMedia, Barco ClickShare, Mersive Solstice, and UC-native wireless — for BYOD conference rooms and collaboration spaces.
