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.The picture quality of digital TV signals is subject to quite different effects and influences than that of analog TV signals. ... Neither does linear or nonlinear distortion have any direct effect on the picture and sound quality in digital television but in the extreme case it, too, leads to a ... All video compression algorithms work in blocks, i.e. the image is in most cases initially divided into blocks of 8 x 8 pixels.
