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.

2.0 out of 5 stars For electronics experts only!, May 27, 1999

By A Customer

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.

5.0 out of 5 stars Great book for analog scrambling., February 10, 1999

By	[e-mail] (Fortaleza, Brazil) - See all my reviews

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.

4.0 out of 5 stars The ultimate reference book on the subject, April 2, 1997

By A Customer

This review is from: Video Scrambling & Descrambling: for Satellite & Cable TV (Paperback)

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
