Video Demystified - A Handbook for the Digital Engineer, 4th Edition

 

 

To begin with, the 4th edition of this book was released in autumn 2004, so all reviews earlier than that are referring to previous editions. I think that too many people buy this book and are expecting either "Video Algorithms Demystified" or "Video Processing Demystified". That is entirely understandable since "Video Demystified" could be talking about one or several areas of video and until you purchase the book you don't really know which one. This book should probably be relabeled as "Video Systems Demystified" to cause a minimum of confusion.

This book is most suitable for electrical engineers that are interested in video signals and their diagrams, video interfaces, connectors and their pin-outs, voltage levels, and digital data and video formats. There are many diagrams showing, for example, typical scrambler and descrambler circuits. The chapters on the video standards (MPEG-1,2,4) do a pretty good job of detailing the format of the video data as it is encoded, including all of the possible header fields, but there is virtually no discussion on any of the compression and motion estimation algorithms that do the actual encoding. There is one chapter on video signal processing, and it is very superficial.

The CD-ROM contains a large variety of color test images useful to video engineers trying to determine if their video system has any problems, and if so, produce a diagnosis. The one item in this book of particular interest to people with more of a computer science/algorithm interest in video would be the source code for MPEG-1, MPEG-2, H.261, and H.263 video encoders and decoders present on the CD. However, I have not tried out these decoders myself, so I cannot speak to their functionality.

In summary, if you are an electrical/electronics engineer involved in video electronics I highly recommend this book. If you are a programmer or someone interested in the algorithms of video processing, this book will probably be only moderately (3 stars) helpful. Thus, I split the difference for a 4 star rating. I notice that Amazon only shows the content for the 3rd edition, so I show the table of contents for the 4th edition next:
