Introduction to Digital Video, 2nd Edition

Book Description

Covers the essential fundamentals of digital video: from video principles, to conversion, compression, coding, interfaces and output.

Written for television professionals needing to apply digital video systems, equipment and techniques to multimedia and /or digital TV applications, as well as for computer system designers, engineers, programmers, or technicians needing to learn how to apply digital video to computer systems and applications. The text is based on the acclaimed industry `bible' The Art of Digital Video, but covers only the essential parts of this larger reference work.

It starts right from the basics from what a digital signal is to the how digital video can be applied.

John Watkinson is an international consultant in Audio, Video and Data Recording. He is a fellow of the AES, a member of the British Computer Society and Chartered Information Systems Practitioner. He presents lectures, seminars, conference papers and training courses worldwide.
