On September 1, 2021, the first step in the roadmap towards second-generation digital terrestrial technology takes place: all broadcasters will have to switch from the old Mpeg-2 audio / video encoding to the new one. Mpeg-4. Many have already been doing this for months and the result is the frequent movement of the channels between one Mux and another.
This is because with the new coding, to transmit a channel, it takes about half the space in the radio frequency spectrum, so it is possible to transmit the same channels with fewer frequencies occupied. Part of the freed frequencies have already been assigned to telephone operators for the 5G data network. Therefore, even at the beginning of July, the shifts of channels, both on national Muxes and on regional and interregional ones. In some cases, broadcasters choose to move from one Mux to another, or to eliminate one or more duplicated channels. Let’s see what happened in the first week of July and which channels have undergone changes.
Digital terrestrial: national news
In the national Mux Cairo Due there has been no canal for a few days La7D HD: the network of the Cairo group dedicated to women now broadcasts only in standard resolution on the LCN numbers 29, 229 and 529. It is not excluded that in the next few days La7D HD will return to a new LCN.
In the Mux Canale Italia, on the other hand, she returned to LCN 170 and 179 Italy 3 (even if it still has the Italy 2 identifier). The same broadcaster comes from Mux Retecapri (where it had identical LCNs), from which it has now disappeared. Nothing changes for users: they will always find Italia 3 at numbers 170 and 179.
Digital terrestrial: the news in Northern Italy
The broadcaster has been eliminated from Mux Studio 1, which broadcasts in Veneto, Piedmont, Lombardy, Emilia Romagna and Valle d’Aosta Galaxy TV 2 (formerly LCN 170). That broadcaster was actually the duplicate of Galaxy TV (LCN 183), therefore also in this case the offer of the channels does not change for users.
The LCN 170 of the Mux Canale Italia, however, now remains only for the aforementioned Italy 3 which in Northern Italy is broadcast within this Mux.
Digital terrestrial: the news from Central Italy
Going down towards Central Italy, on the other hand, in the Marches there are several changes within the Mux Vera TV: in fact, the channels have been eliminated. The 9 (LCN 76), La 8 (LCN 81), Not TV (LCN 89), We are not TV + (LCN 605), art and fashion (LCN 168), fM TV (LCN 211).
