Handbook on digital terrestrial television broadcasting networks and systems implementation iii Editors’ Foreword In 2002 ITU published its first Handbook on digital terrestrial television under the title Digital terrestrial television broadcasting in the VHF/UHF bands1 as guidance to engineers responsible for the implementation of digital terrestrial television broadcasting (DTTB). In the Handbook, new digital broadcasting technologies were explained in detail, for example a splendid description of the Discrete Cosine Transform (DCT) coding that is the basis of all past and present TV compression systems, as well as a very instructive chapter on signal power summation. Most of that content are not repeated in this new Handbook on digital terrestrial television broadcasting networks and systems implementation. Therefore, the version 1.01, which was published by ITU in the year 2002, has not lost value and should still be consulted. Since 2002, DTTB has tremendously evolved, not only in technical but also in regulatory aspects. For example, at the turn of the century, MPEG had just started to develop the compression scheme MPEG-4, and HEVC was not known at all. In two sessions, in 2004 and 2006, the important ITU Regional Radiocommunication Conference RRC-06 was held in Geneva and agreed a new frequency plan for digital broadcasting in Region 1 (except Mongolia) and in Iran.
