DVB-T2 terrestrial television tests carried out by TVP and Emitel are in full swing, and as Dolby Laboratories informed today, they also include tests of the channel using Dolby AC-4 sound. The new technology of sound transmission was implemented in the case of the TVP Kultura HD channel, which is one of the few available under the DVB-T2 tests, currently in Silesia and Małopolska.
“The choice of Dolby AC-4 is appropriate for many reasons, including better sound quality, affordability, ease of integration with the existing distribution network, the high degree of distribution of Dolby AC-4 in modern TV sets, and finally bandwidth efficiency during frequency change “ Explains Javier. Foncillas, Dolby Europe’s Vice President, Commercial Collaboration.
According to the press release, over 70 percent. UHD TVs delivered to Europe from the beginning of 2020 have the ability to decode Dolby AC-4. Most of the owners of the latest TV sets can test on their own how the new technology works in practice. When Emitel from TVP started DVB-T2 tests in the middle of last month, there were over 6 million Poles in Silesia and Lesser Poland. Ultimately, however, the tests are also to cover Warsaw, Gdańsk and Poznań.
The ongoing tests (and ultimately implementation) of DVB-T2 are related to the development of the 5G network. It is about the frequencies on which DVB-T terrestrial television is currently broadcast. The 700 MHz band will soon be used for 5G and therefore changes are needed. DVB-T2 has been designed in such a way that the 700 MHz band has been released.
