Digital television MPEG-1, MPEG-2, and principles of the DVB system
Written as an authoritative introduction, this text describes the technology of digital television broadcasting. It gives a thorough technical description of the underlying principles of the DVB standard following the logical progression of signal processing steps, as well as COFDM modulation, sourc...
