USB Video Interface
USB video interfaces cannot support the high data rates required for professional video
use, so they are not commonly used. USB video interfaces are usually used for
converting analog video sources to a digital signal for capture.
Video Signals and Connectors
When you capture and output, the type of video signal you use to connect your
equipment is a critical factor that goes into determining the quality of your video.
Video camcorders, decks, and monitors can use different types of signals, depending
on the environment they are intended for. Consumer equipment usually has limited
video signal choices; professional equipment gives you the greatest range of options.
Here are the most common video signals used on today’s video devices:
