Hi,
The “Instant Access” motto makes 100% sense for this book: all information that you need is provided there, very easy to find and digest. It is not a book on algorithm design or DSP implementation, but is certainly a good reference on terminology, concepts, and explanations of technical matters related to Digital Video. It is certainly a reference book for an engineer to find “Instant Access” information to any topic related to Video. Personally, I’d liked it had more “How-To” information, but overall is a nice-to-have reference.
Regards.
