Product Description
Video Scrambling and Descrambling for Satellite & Cable TV provides the "how and why" of encoding and decoding video signals. Most of the currently used methods are discussed, with the necessary technical background. Since digital scrambling methods will undoubtedly supplant analog methods, information on analog/digital conversion, phase-locked loops, digital techniques, and IC data sheets are included.

In this new edition the authors incorporate the many developments in this field since 1986. They elaborate the basic information on scrambling given in the first edition, and discuss current scrambling systems such as Tri-mode, SSAVI, and Videocipher II. Looking back at the "gloom and doom" predictions made in the 80s, they discuss which have proven correct, which have yet to be realized, and which have been wrong. Their discussion of basic circuitry now includes some new IC devices, and the section on political, legal and consumer aspects of scrambling has been completely updated. New digitization techniques and construction data, decoder circuitry, audio scrambling techniques, manufacturers' data sheets, US Patents, and current developments such as digital audio are also covered in this updated version.

CUSTOMER REVIEWS (Average Customer Rating: 3.0 based on 4 reviews)

50% Useful; 50% Useless

Half of the book's pages are regarding the topic but the rest are descriptions of various ICs(Integrated Chips) that are used. These information are useless unless they are intended to describe specific ICs being used in a circuit project. These information are normally taken from Chip Manufacturer Circuit Manuals which are called "Databooks"

Having or not having these IC information in this book will have no difference.

This book will suit electronics engineers and physicists as this book is heavy on theory and measurements. It is not intended for electronic experimenters or enthusiasts who are more interested on the practical side of electronics and physics.

If you are the type who wants to put electronics into action or is the type who wanted to use eletronics knowledge to build a working circuit on Video Scrambling, etc. DON'T BUY THIS BOOK. This is not for you.

But if you are the type of person who loves the Theoretical side of Electronics being applied on Video Scrambling, then BUY THIS BOOK! I'm sure you'll love all the explanations backed by quantitative measurements this book covers on Video Scrambling and Descrambling.

For electronics experts only!

This book is geared towards electronics engineers. Unless you own at least an ocilloscope and a lot of other electronics equipment, this book will be useless to you.

Great book for analog scrambling.

Personally, I liked this book so much. It brings many information and classical circuits and patented for scrambling of video signals. The approach, however, is for systems NTSC. It also brings information on digital coding.

The ultimate reference book on the subject

I have been using this book for a little while now, and I had to just buy my own copy (some "friends" I have :) ). If you have some signal processing background, this is the book for you, but it is probably too technical for the average electronics tinkerer or computer geek. It provides great explinations and useful circuits that let you dive into the world of cable scrambling and descrambling. The theorys presented in this book can also be used to scramble signals on other kinds of systems for semi-safe transmission
