A curated path from “what is a signal?” to designing, commissioning and supporting conference rooms, AV-over-IP and control systems. No prior knowledge assumed.

The mental model every AV professional carries: sources, transport, processing, destinations — and the units used to measure all of it.
Pixels, frames and color — and how they multiply into the bandwidth figures that decide which cable, switcher or extender you can use.
HDMI, DisplayPort and USB-C — plus the two invisible conversations (EDID and HDCP) behind most “no picture” service calls.
Choosing, sizing and lighting the screen — LCD, OLED, direct-view LED and projection, and the room they live in.
Sound in the air and sound on a wire — frequency, levels and cabling.
Capturing speech, delivering it evenly, and shaping it in between.
Getting any source to any screen — matrix switchers, scalers and extenders.
Enough networking to design, commission and defend an AV system on a corporate LAN.
Encoders, decoders and networked audio — the architecture replacing fixed matrices.
One button that turns on the room — and everything that makes it reliable.
