4.0 out of 5 stars Imperfect, but useful reference 11 Mar 2012
By Dr Mike - Published on Amazon.com
Format:Hardcover|Vine Customer Review of Free Product (What's this?)
I was interested in this book mainly because of the content dealing with vision and less on the technical aspects. I've been involved in ISO and ANSI vision standards as part of my profession, including color standards. I think a reference book that combines visual and technical aspects of imagery fills an important niche in vision science and optical engineering. With that in mind, I was impressed with how much information was covered in this reference book. I will be using it for my work.

Unfortunately, I think the parts of the book that deal with vision are the weakest parts of the book. Clearly the author doesn't have formal training in this area and is not up to date on what takes place in vision science and color science. However he does have a rudimentary understanding and that is perhaps enough for the primary readership he is reaching. As an example, he mentions that researchers in the United States do not use SI units. That is completely false and has been false for well over 30 years. All vision scientists such as myself have been using international units for decades. For someone who is supposedly an expert to make such a blatently untrue statement seems odd to me.

The authors gets some things incorrect about psychophysical testing and makes assumptions that aren't true. He clearly has read some older texts on the subject and thinks these methods are still practiced, when they are not. It is a pity that he didn't invite a co-author who was a vision scientist or a color scientist to help write the book, or at least bring it up to date. Anyone reading the sections on vision and physiological aspects of color should take the information in the book with a grain of salt. It is good as an introduction, but shouldn't be used as a complete or even accurate reference on the subject.

I did notice some errors in some of the figures. Some even gave me a chuckle, but such things do happen when you have one author and apparently no professional editorial assistance to find such errors before printing. The errors I found were not serious, but there are technical portions of the book that are not in my area of expertise and I can't speak for errors in those sections.

One of the most frustrating aspects of the book is that it is so poorly referenced. I took off a star for that alone. This is supposed to be a reference book, but there are very few references and the ones that are there, are thrown in on the margins as kind of an afterthought. There is no citation of these back to the text, plus there are important sections in the text that beg to be cited. The references are also not listed in order at the end of each chapter. This is a shame and I'm sure it happened because the author has no formal scientific training to understand the importance of citing his sources so the reader can research a topic in greater detail from the original source.

Despite the weaknesses of the book, I will keep it and hope to use it occasionally or refer others to it. I think it fills an important void. It would have been a better book if it included input from a vision scientist and if the author had correctly cited his source material.

5.0 out of 5 stars The BIBLE for all things Digital Video! 15 Mar 2012
By Paulo Leite - Published on Amazon.com
Format:Hardcover|Vine Customer Review of Free Product (What's this?)
This is an impressive book. It goes over all aspects regarding Digital Video. Really, it leaves no stone unturned - to a point where from a certain chapter on, you must have some technical education and experience to keep on reading. This is not a book for a casual reader who only cares about knowing a thing or two about HD formats. Instead, this is a book for those who REALLY work with HD equipment on an everyday basis... or someone considering a career in electronic engineering or related areas of expertise. People who work with editing software and digital special effects should also benefit from this book. Not to mention Cinematographers who want to be future-proof and camera crews - for those it's a MUST have it.

I was expecting a much simpler book... but since I do work with film/video (I'm not new to the subject), I found the book amazing. It trully explains everything you might want to know about HD video. HD video is a subject that is ever evolving... so it is certain that this will not be the only book you'll need... but right now, it is one that you must have.

RECOMMENDED!

4.0 out of 5 stars Great reference, some shortcomings 22 April 2012
By E. Weber - Published on Amazon.com
Format:Hardcover|Vine Customer Review of Free Product (What's this?)
This is overall a great book on topic of digital video and cover a lot of aspects from basic concepts of digital filtering all the way to compression technology.

A lot of subjects are discussed but the depth of the discussion is very dependent on the topic.
For example you will find all the technical details related to PAL, NTSC or HDTV, historical views etc but only high level discussion on video compression.

I own both editions of the book and in my opinion the second edition doesn't add much. The preface of the second edition highlight the convergence of TV and Internet but almost no new content related to Internet delivery of video is present in the book.

4.0 out of 5 stars absolutely detailed and full of nuances 22 Feb 2012
By W Boudville - Published on Amazon.com
Format:Hardcover|Vine Customer Review of Free Product (What's this?)
Poynton provides an absolutely detailed discussion of the main methods used in digital video. His book goes beyond the level of discourse typically found in other books. Nuances elided over in those texts are delved into here.

One example is this. He talks about representing digital numbers in two's complement. If you have studied electrical engineering or computer science, you should know what the latter is. But there is one aspect of two's complement that standard texts only sometimes mention. Wrap around. Where suppose you fix the number of bits. Then take the largest positive number that can be represented in two's complement, and add 1 to it. You get the smallest negative number. So what, you might say? Well in video algorithms for signal processing, this is disasterous. You can't have a noise generated lowest order bit trigger this wrap around. So saturating integer arithmetic has to be used. At the very lowest level of computation. The closest comparison in standard CS texts is the Hamming cliff property of standard binary encoding.

If you ever wanted to know all the gory details of NTSC and PAL, and the differences between these standards, or about the MPEG standards, the book furnishes them. The discussion includes historical perspective on how those arose and on related but not obsolete ideas like SECAM. You need enough maths background to understand the discrete cosine transform if you want to follow the MPEG and JPEG explanations.

What is entertaining and instructive are Poynton's musings on metadata. Most other discussions of metadata give examples to the effect that "this [thing1] is metadata relative to that [thing2] which is data". Poynton reminds us that there is no inherent absolute distinction. What is considered metadata might be by convention or relative to a given use context. If the use changes, so might what is considered metadata.

For practical uses of the book, the later section on the colour standards of RGB, CMYK etc and how to convert between these can be very handy.

You might also look at the chapter on timecodes. The equivalent in importance of the primary key in relational databases, and the basis for all correct audio and video recordings. The book also explains how for TV signals, this timecode changed out of necessity when there was the transition from black and white to colour TV.

4.0 out of 5 stars Great text on digital video 6 May 2012
By Jon Norris - Published on Amazon.com
Format:Hardcover|Vine Customer Review of Free Product (What's this?)
This is a full blown, high level textbook on digital video and high definition. It is not for those who want to know how to post their phone cam videos on YoutTube or Facebook. (Although I'll admit there might be some overlap there...)

This is hardcore, math intensive, belly of the beast technology information, well written and presented in a high quality textbook.

While it is about digital video, there is also quite a bit of information about analog video, and how that differs from digital. As someone who has worked in professional analog video for over 30 years, I found that grounding in the historical information to make the text far more useful and accessible.

It also cemented the author's understanding and knowledge of video in my mind. Many people today gloss over the historical roots which are essential to understanding many conventions in video. This author integrates that information very well.

I found the author's writing style transparent, clear and detailed, without the excessively florid prose one finds all too often in textbooks or academic works. While much of the topic is highly technical and deeply math laden, the author is able to communicate this information clearly and concisely, which is a refreshing break from most such texts. The ability to convey complex information in such a manner is rare and not as well appreciated as it should be.

The material covered ranges from a definition of raster and pixel displays to High Definition color coding and signal processing. Topics include; video compression, filtering and sampling, digitization and reconstruction, perception and visual acuity, luminance and color science, gamma, component video, timecode, interlacing, signal processing, JPEG and motion JPEG, and much, much more.

The concepts are explained clearly with diagrams and graphs when needed, and the associated math is well presented.

While the material is far more detailed and in-depth than anything I would use in my daily work, I nevertheless found much interesting material and clarification of topics which do impact my routine video use.

Highly recommended to anyone interested in the deeper technology behind video today.
