SDI
SDI (Serial Digital Interface) is a standard way of sending high-quality video signals in professional TV and broadcast settings. Think of it like a special type of cable and connection system that TV stations and production studios use to move video from cameras to control rooms, or between different pieces of video equipment. It's similar to how HDMI works in home electronics, but SDI is made for professional broadcasting needs. When you see this term in resumes, it usually means the person has experience working with professional broadcast equipment and understands how to set up and troubleshoot professional video connections.
