Table 8. Number of satellite SSTV, HDTV and 4K UHDTV channels for the various transmission parameters.
6.2. 4K UHDTV in digital terrestrial television (DTT) Initial tests 4K UHDTV in digital terrestrial television systems were carried out in 2012 in Japan
and South Korea by KBS and NHK still using unstandardized HEVC video compression. Later
tests were done in other countries. Table 9 [26] gives the basic test characteristics of 4K UHDTV
in digital terrestrial television (DTT) networks in the world.
Technicolor has successfully conducted tests to broadcasting terrestrial 4K UHDTV content.
Broadcasting used American ATSC 3.0 standard, trough Sinclair Broadcast transmitter [27].
Technically speaking, this is the world premiere of the use of scalable HEVC (SHVC) video
coding, MPEG-H compression standards, as well as MMT MPEG A/V standards. The test was
performed in the Sinclair Broadcast experimental facility. The new technology allows you to
receive signals via conventional antenna, as well as through mobile and tablet devices.
Based on technological profiles and the typology of the various countries, the report predicts
that the demand of end users and the transition to the new standards take between 3 and 12
years old. Markets that were among the first to adopt new technologies will likely take between
three and six years to the current broadcasting possibilities of yarn on a combination of DVB-

T2 MPEG4/HEVC, SDTV/HDTV/UHDTV (4K). The third profile that refers to the HDTV/
UHDTV (4K/8K) is supposed to happen between 2023 and 2030. The report says that the DTT
platform is currently threatened due to scarcity of radio spectrum, as well as plans for the
redistribution of 700 MHz range, which will reduce the available capacity by an average of
30%.
