Preface

The goal of this book is to serve as a comprehensive reference book for readers in the field of electronic engineering with a background in digital signal processing and telecommunications (only fundamentals and not necessarily with advanced knowledge in this area). The target readers include researchers, engineers, service providers, market analyst, policy makers, and IT staff who work in the digital video broadcasting area. The book may serve as a textbook for undergraduate courses of one semester or short courses if the instructor only focuses on the fundamental concepts and as a graduate textbook if details need to be addressed. It can also serve as a continuing education textbook for those in the DTV industry who want to obtain the latest updates.

Chapter 1 introduces the basic concepts of the digital television (DTV) system, including a historical perspective and the constitution of the DTV system with emphasis on the terrestrial broadcasting system. Chapter 2 presents the characteristics of the harsh terrestrial transmission environment for DTV signals, including propagation loss, the “shadow effect” by terrain factors, the multipath effect, and the Doppler effect when transmitters and/or receivers are under mobility. Chapter 3 covers the fundamentals of channel coding, including interleavers that help convert burst errors into random errors for better error correction capability, especially those being adopted in the digital television terrestrial broadcasting (DTTB) system. Chapter 4 mainly introduces the modulation techniques in various DTTB systems. The basic concepts of coded modulation, which jointly optimizes channel coding and digital modulation to best control errors by nonideal effects for transmission are also addressed. Chapter 5 provides information on the frame structure, channel coding, modulation, and major parameters of the existing first-2 generation international standards, especially for the newly developed digital television/terrestrial multimedia broadcasting (DTMB) system. Chapter 6 gives general information on the second generation of the DTTB system, which can provide over 30% increase in data throughput by adopting higher constellation mapping and longer coding length for better error correction capability. Chapter 7 focuses on the design and implementation issues of the DTV receiver, including carrier synchronization, timing recovery, channel estimation, equalization, decoding, and de-interleaving, with concrete implementation examples of these algorithms. Chapter 8 addresses issues such as coverage and network planning of DTTB networks with a detailed introduction of the single-frequency network (SFN). A brief introduction of the characteristics and implementation of the diversity technology is also provided. Chapter 9 gives a general description of the system-level performance test of the DTTB systems, including the physical meaning of the test item, test methodologies/procedures, and for information purposes the test requirements using DTMB as an example. Chapter 10 describes the technical features in detail of four multimedia mobile broadcasting systems. Even though some systems are out of favor nowadays due mainly to the spectrum issue and the tough competition, the featured technologies of those systems have been adopted by other systems.

With 10 chapters and quite broad topics, the instructor may arrange the topics in different ways depending on the time length of the course. Chapter 2 is more physics related while Chapters 3 and 4 provide fundamentals of coding and modulation. These three chapters, together with Chapters 5, 6 and 10, can help readers better understand the major design issues and constraints of the DTTB systems. If the targeting audience is interested in knowing receiver design, Chapter 7 and some of the references can serve this purpose, and network planning is addressed for service providers. For engineers whose job function is testing, Chapter 9 provides a good topic for continuing education purposes.

The authors of this book have actively been involved with fundamental research on the core technologies of DTTB systems (i.e., time-domain synchronous OFDM, TDS-OFDM), hardware implementation and the performance validation of the DTTB receiver (more specifically, the DTMB receiver), and the international standardization process, and some technical context directly comes from their research and development work. This valuable experience has motivated the authors to write this book and share their research results and comprehensive understanding of the DTTB system with readers who work in this area.

The authors would like to express their sincere appreciation for the contributions of Dr. Nim Cheung. Without his kind recommendation, encouragement, and always on-time help, this book would not have been completed. The book is a joint effort of researchers working at Tsinghua University, China. The authors are indebted to Professor Jintao Wang, Professor Chao Zhang, Professor Changyong Pan, Professor Zhaocheng Wang, Professor Fang Yang, Professor Yonglin Xue, Professor Kewu Peng, Professor Yu Zhang, Professor Hui Yang, Dr. Qiuliang Xie, and other team members for their much valuable contributions.

The authors would also like to thank all the comments from the reviewers of this book proposal as well as this book. Their much valuable comments and suggestions allowed us to better choose and arrange all the context of the book. Finally, we also thank the great help and patience from Mary Hatcher and Brady Chin of John Wiley & Sons, Inc. Without their kind guidance and assistance, it would have taken much longer with more painful effort to finish the book.

1Basic Concepts of Digital Terrestrial Television Transmission System

1.1 Introduction and Historic Review

Television is a word of Latin and Greek origin meaning “far sight.” In Greek, tele means “far” while visio is “sight” in Latin. A television (TV) system transmits both audio and video signals to millions of households through electromagnetic waves and is one of the most important means of entertainment as well as information access. With the never-ending technological breakthroughs and the continuously increasing demands of audio and video services, the TV system has evolved over generations with several important developmental periods in less than a century.

1.1.1 Birth and Development of Television Black-and-White TV Era

In the mid-1920s, the Scottish inventor John Logie Baird demonstrated the successful transmission of motion images produced by a scanning disk with the resolution of 30 lines, good enough to discern a human face. In 1928, the first TV signal transmission was carried out in Schenectady, New York, and the world's first TV station was established by the British Broadcasting Corporation in London eight years later. After World War II, the black-and-white TV era began. Detailed technical and implementation specifications of TV service, including photography, editing, production, broadcasting, transmission, reception, and networking, were gradually formulated. With the ever-growing popularity of TV viewers, the color TV with better watching experience was invented to simulate the real world.
