Frequency changes for the terrestrial television will begin at the end of JulyPublished 01.06.2015
The alteration works for the broadcasting frequencies in Digita's terrestrial television network in the UHF frequency band will begin at the end of July. The frequency changes covering the whole country will be completed by the end of 2016. The changes will be made a few regions at a time. The first changes will be made during the last week of July in Northern Finland at the transmitter stations located in Suomutunturi, Kemijärvi and in Sarivaara, Salla. In housing companies with a joint antenna system, an antenna contractor is required to retune the system's main amplifier. Normally, there is no need to modify the antenna systems in single-family houses.
The first frequency changes will be made at small transmitter stations in the northern parts of Finland. The broadcasting operations of these stations will be interrupted during the alteration works. Information on the exact dates when the interruptions occur will be issued separately in the regions. In August, the transmitters in Salla, Sodankylä and Utsjoki will be modified. Later in the autumn, the alteration works will continue at the main transmitter stations located in the northern parts of Finland. During the alteration works, the TV broadcasts of the stations will be implemented in parallel both on the old frequencies and on the new frequencies. Digita will issue per region information on more exact schedules and the schedules will be available on FICORA's website, too.
Due to the frequency changes, the antenna systems of the housing companies and public buildings that receive television broadcasts via a joint antenna network have to be modified. For this reason, the property managers responsible for real estates with a joint antenna system must contact a local antenna contractor in good time before the frequency changes in the region will begin. The densely populated regions with a high number of joint antenna real estates should take into account an eventual backlog of the alteration works concerning antenna systems.
All the main amplifiers of joint antenna systems must be retuned after the frequency changes have been made in the region. In some cases, the main amplifier of the antenna system may have to be replaced in order to carry out the changes.
After an antenna installation engineer has modified the joint antenna system of the real estate, the residents of the housing company must perform the channel search for their TV receivers again. The newest receivers usually search the channels automatically.
The housing company is obligated to inform residents of the date when the channel search must be done.
Alterations works do not have to be carried out in detached houses and in the single-family houses without a joint antenna system. If the antenna is in order, the channel search for TV receivers is a sufficient procedure after Digita has made the frequency changes in the region.
The frequency changes are based on the Communications Policy Programme for Electronic Media, issued in 2012 by the Government to the Parliament of Finland, as well as on international decisions. The so-called 700 MHz frequency range, used by the terrestrial television network, will be switched to the use of wireless broadband at the beginning of 2017. In addition to introducing the efficient DVB-T2 broadcasting technology, broadcasting frequencies of TV networks must be rearranged so that the amount of television services is not reduced due to the terrestrial television's smaller frequency range. This is why a significant number of the frequencies used by the main transmitters and gap-fillers of Digita's UHF broadcasting network will change.
The DVB-T2 technology is already in use in the multiplexes of the VHF range. After 2016, the use of the technology will gradually increase also in the UHF range, whereas the number of the programmes broadcast with the current DVB-T technology will decrease. Broadcasting the Finnish Broadcasting Company's channels by means of both the current technology and the new technology will continue for several years. If the Finnish Broadcasting Company's HD programmes subject to the must-carry obligation can be received in the region, housing companies must, however, ensure that the antenna system of the housing company enables the residents to receive the HD programmes.
