This book was created to provide the man in the field, be he a transmitter network planner, a service technician at a transmitter site, a technician responsible for MPEG-2 encoders and multiplexers in a studio or a playout center, an engineer working in a development laboratory or even a student, with an insight into the technology and measuring techniques of digital television. It concentrates deliberately on the practical things of importance and attempts to include as little mathematical "ballast" as possible.

Klappentext

Digital Television closely examines all present-day TV transmission methods. These include MPEG, DVB, ATSC and ISDB-T. DVD is also discussed. The text covers these subjects in a practical-minded manner. Although mathematical formulations are used, they are in most cases only utilized to supplement the text. The book also contains chapters dealing with basic concepts such as digital modulation or transformations into the frequency domain. A major emphasis is placed on the measuring techniques used on these various digital TV signals. Practical examples and hints concerning measurement are provided. The book starts with analog TV base and signal, continues with MPEG-2 data stream, digital video, and digital audio, and then moves on to compression methods. After an excursion into the digital modulation methods, all the mentioned transmission methods are discussed in detail.
