An Introduction to Video and Audio Measurement, 3rd Edition

Book Description

What do we measure and why? Peter Hodges explains the answer to this question in approachable language and with clear illustrations. Newcomers to the video industry, as well as those already established, will find this uniquely readable guide to the basics of a complex subject. Building on the success of the two previous editions of this popular title and covering both analog and digital video, the third edition includes new sections on audio measurement, high definition video, and innovative techniques of test and measurement.
