The transmission of terrestrial television signal in the DVB-T / MPEG4 standard has been conducted for 10 years and the standard itself appeared in the world much earlier. The change of the MUX-3 transmission standard planned in Poland in December 2023 to the newer and more effective DVB-T2 / HEVC standard will enable the introduction of new television channels to the terrestrial television offer. All channels can be broadcast in HD and some perhaps even in 4K quality.

The implemented changes are favourable for viewers. After the change of the transmission standard, it will be possible for all channels to be broadcast in much better, HD quality. Moreover, a new, more effective standard will allow broadcasters to add new channels.
