Digital terrestrial television


Digital terrestrial television (DTTV or DTT, or DTTB with "broadcasting") is a technology for terrestrial television in which land-based (terrestrial) television stations broadcast television content by radio waves to televisions in consumers' residences in a digital format. DTTV is a major technological advance over the previous analog television, and has largely replaced analog which had been in common use since the middle of the 20th century. Test broadcasts began in 1998 with the changeover to DTTV (aka Analog Switchoff (ASO) or Digital Switchover (DSO)) beginning in 2006 and is now complete in many countries. The advantages of digital terrestrial television are similar to those obtained by digitising platforms such as cable TV, satellite, and telecommunications: more efficient use of limited radio spectrum bandwidth, provision of more television channels than analog, better quality images, and potentially lower operating costs for broadcasters (after the initial upgrade costs).

On March 20, 2013, it was announced that Thomson Broadcast had won a major contract with The Second Authority for Television and Radio for the extension of its nationwide DVB-T/DVB-T2 network. The Second Authority's order for new infrastructure includes two new multiplexes on thirty sites including three single frequency areas. This major deal incorporates a three-year service agreement for the global transmission system.

On May 8, 2008, the Ministry of Internal Affairs and Communications announced that 43.7% of homes had DTT (ISDB-T) capable TVs and/or tuners with DVD recorder by end of March 2008. It had been 27.8% one year before, and the ministry was expecting 100% penetration by April 2011. On 27 April 2009, National Association of Commercial Broadcasters in Japan (NAB) a new official mascot, Chidejika, to replace Tsuyoshi Kusanagi after he was arrested on suspicion of public indecency.

Even though MCOT's trial was a success, the future of the digital terrestrial television transition has become uncertain, especially after the end of Somchai Wongsawat's tenure as the Prime Minister and the beginning of successor Abhisit Vejjajiva's reign in favor of his concept.

Flanders has no free-to-air television, as Dutch-language public broadcaster VRT shut off its DVB-T service on December 1, 2018 citing minimal usage. VRT cited that only 1 percent of Flemish households made use of the terrestrial signal, and that it was not worth the 1 million to upgrade to DVB-T2. After some outcry over the loss of terrestrial coverage, VRT's channels were added to TV Vlaanderen's subscription DVB-T2 package called Antenne TV alongside all major Dutch-language commercial channels.

The BCI (now BAI) received three conditional applications to operate the three muxes which were presented to the public on 12 May 2008. It decided in principle to allocate the license to Boxer DTT Ltd, a consortium made up of the Swedish pay-DTT operator Boxer and the media group Communicorp at its board meeting on 21 July 2008.

DTT launch in Poland was scheduled for Autumn 2009. Regulatory disagreements delayed its tender and approach until resolved and the multiplexes available for DTT were reduced to 3 and the 2nd was licensed in the Autumn of 2009. The reduction from 5 to 3 enabled mobile TV and broadband to get more spectrum allocation. Muxes 2 and 3 therefore had limited coverage until ASO. Polsat, TVN, TV4 and TV Puls have officially applied to reserve space on the countries first multiplex set to start in September. Wirtualne Media is given as the source of the story. The public broadcaster's three main channels TVP1, TVP2 and TVP Info had already been allocated capacity on the multiplex.
