| This book is intended for use by engineers, technicians, students, and anyone interested in acquiring a working knowledge of the principles behind digital television and digital radio broadcasting. It assumes that the reader already has some knowledge of modern color television engineering. It treats in detail the European digital television standards, however, as it describes the universally accepted digital encoding practices, it will have general appeal. It also details the digital broadcasting systems adopted by the United States and other countries. The book begins in Chapter 1 with a general overview of the recent developments within digital television (DTV), and a review of some of the more important organizations working in this field. It also introduces the concepts of compression and redundancy, which are used in subsequent chapters dealing with encoding within studios.
It is intended to give the reader an in-depth understanding of the more important issues related to digital television engineering. The subject matter is backed up by the usage of references to more detailed information sources. Also, the topics are supported by the usage of diagrams and schematics, which give functional descriptions and help to illustrate the principles. It is not the purpose of the book to illustrate digital television techniques mathematically and hence this has been kept to a minimum. It is clear that at the time of writing this book great advances in digital signal processing (DSP) are having a profound effect in driving this technology forward. This will also yield improvements in equipment performance, and with very large scale integration (VLSI) of chip circuitry, the cost of this equipment will be reduced. |
