Video Basics

How a picture gets from a source to a screen, and what breaks on the way

Most video problems on a live job are not mysterious, and almost none of them are solved by guessing. This book covers what a picture actually is, pixels, resolution, aspect ratio, frame rate and colour, how it travels as a signal, which connector carries what, what a switcher and a scaler actually do, how projectors, panels and LED walls differ, and how to trace a video chain when nothing appears on the screen.
