Planning migration of digital terrestrial television from DVB-T standard to DVB-T2 in Republic of Croatia

On 31st December 2010. analog television in Croatia was completely switched off and was replaced by DVB-T television standard. Because of that, it became possible to provide more TV channels with higher quality and freed up frequency band for first digital dividend, which is now used for LTE mobile broadband services. Nowadays, newer and more advanced standard DVB-T2, which is the extension of DVB-T, is being implemented in many countries. In Croatia DVB-T2 is used for terrestrial pay TV platform. DVB-T2 offers significantly higher network capacity in the same frequency band which enables more television channels, easier migration to HD services and possibility to free up additional frequencies for second digital dividend. Second dividend frequencies are especially fitted for covering broad rural areas with wireless broadband services that can reduce digital gap. Such benefits would have positive impact on economic sustainability of traditional broadcasting media in competitive digital economy. In this paper we analyze lessons learned from analog switch off and if the opportunity to introduce citizens with new technologies through media campaigns is exploited and is sufficient attention to media literacy taken, as well as motivation for further migration to DVB-T2 standard from market, regulatory, technical and economy perspectives. Future development of terrestrial broadcasting will be also discussed and compared with other broadcasting platforms (e.g. internet, cable, satellite). Predicted reduction of TV broadcasting costs, migration costs, need for government subsidy to buy new DVB-T2 receivers and other cost factors of the transition to DVB-T2 will be discussed. Recommendations to the media and regulatory bodies will be given with areas that they need to pay attention to, in order to increase media literacy of citizens. That analysis is a basis for identifying key prerequisites, benefits, obstacles and stakeholders in migration to DVB-T2 and enumerates further research areas and questions that have to be answered in order to prepare optimal plan for migration to DVB-T2 from technical, economic, market and society perspectives.
