Abstract

The object of the research is to make an analysis of the current state of the digital tele-broadcasting systems in the world and the transition trends from analogue to digital systems recommended by the International Telecommunication Union (ITU-R) for use in this area are considered. Therefore, the current trend of global transition to digital tele-broadcasting is due not only to the lack of a frequency resource, but also to society’s growing demands for up-to-date information, the need to introduce common global standards and systems for broadcasting systems. expansion of digital tele-broadcasting in the context of globalization, as well as the presence of this transmission technology. In this work, he is dedicated to considering the sustainable development trends of digital satellite broadcasting in the world in the phase of migration from analog to digital technologies in this area. In the final part, the results obtained based on the research and analysis made in recommendations and in the ITU-R database are presented.

Keywords: tele-radio, terrestrial, broadcasting, digital, systems, frequencies, transmitters, transition, satellite, broadcasting, International Telecommunication Union.
