Digital Broadcasting - New Era of Technological Development of Television
All the leading countries in the world switched to digital broadcasting. This process began in the Western Europe and the United States in the 90th of the last century. In developed countries broadcasting in analog format has been changed with digital broadcasting.
Development of innovative technologies in the last 20 years of the last century made the world to see more effective possibilities of frequency resource usage.
Nowadays we have analog TV and radio broadcasting in Georgia. In analog network conditions it is possible to transmit only one channel in 8 MHz frequency band. Transition to digital broadcasting will enable to liberate frequency spectrum i.e. to get “digital dividend". In the frequency band where only one TV channel was available, after transition to digital broadcasting more channels of programming will be possible to transmit.
All this means that the country will be given the possibility to make use of scarce resource of frequency spectrum more effectively and diversely, which will facilitate the development of market competition. Many innovative technologies (for example, 4G broadband telecommunication systems) and services will be introduced. The population will be provided high definition television pictures and voice information, personal and mobile television and interactive services.

International Telecommunications Union (ITU) divided the countries which should transit to digital broadcasting into three regions. Georgia is in the first region along with neighbor Armenia, Azerbaijan, Russia and Turkey. According to Agreement adopted at Geneva Conference in 2006 so-called first region countries and Islamic Republic of Iran have to migrate to digital broadcasting since June 15, 2015. In case of not fulfilling the terms, broadcasting frequencies assigned to the certain country will turn out to be unprotected – analog format frequencies will be covered with digital signal of neighbor countries and the country will remain without broadcasting at all.
Nowadays, International Telecommunications Union (ITU) divided existing 25 broadcasting zones in Georgia into 10 zones for transition to digital broadcasting. According to the Law of Georgia on Broadcasting currently in force, all broadcasting companies are obligated to cover 90 % of broadcasting zone. After switching to digital broadcasting geographical areas of broadcasters operating in Georgia will automatically enlarge.
It is true that the digital format broadcasting switchover process is connected with big financial expanses, but international researches showed that digital television and radio broadcasting
