The main issues of building distribution systems for digital television and radio broadcasting programs are presented. Given are the main quantitative ratios for calculating broadcasting systems when passing signals in the troposphere, in space and over cable networks. The principles of spectral compression of video and audio signals are considered, which allows increasing the bandwidth of standard television channels by 4-6 times. The possibilities of organizing direct interactive access of Internet users via satellite channels and MMDS distribution networks, as well as rapidly developing networks built on VSAT earth stations are discussed.
