Terrestrial and
satellite transmission 

DVB-T2 (Digital Video Broadcasting - Terrestrial) is a system of transmitting television signals via digital techniques. The system is more resistant to signal interference and facilitates the reception of television signals at a considerable higher quality in comparison to the previous DVB-T digital terrestrial television signal. The DVB-T2 system allows for new additional services and functionalities such as searchable EPG, multi-channel audio, interactivity, coding, PayTV, and the further development of high resolution television.

The Republic of Croatia is divided into nine digital regions (Eng. allotments). Inside each allotment, transmission of the DVB-T2 signal is done using the SFN operating method.

Transition to the DVB-T2/HEVC television signal

We successfully implemented the national transition to the standard of digital terrestrial television with the most modern HEVC (H.265) system for video compression which was finalized in November 2020.

The OIV DAB+ platform for broadcasting a digital radio signal offers you the possibility of broadcasting up to 10 radio channels through a single radio frequency with high-quality audio. Besides a multimedia content display, broadcasters can display multimedia content and have additional advertising space in their new program channels.

New DAB+ digital radio services

DLS – display of text symbols on the receiver screen (title of song and performer name, title of broadcast, telephone numbers, brief notifications, etc.)

Journaline – an interactive service with textual information similar to teletext on television which is accessed through a menu.

MOT – (Multimedia Object Transfer Protocol); MOT applications include:

• Slideshow, transmission of web-sites, a series of slides, consisting of HTML linked files organized in a cyclically transmitted tree structure.
• EPG (Electronic Programme Guide) is an electronic version of a printed channel guide.

TPEG (Transport Protocol Experts Group) is a specification developed for transport and travel information (news, navigation, parking, fuel prices, etc.) which can send messages to drivers about traffic in their own language, even if they are abroad.

Analogue FM radio

With 77 transmitter locations, we cover 99% of Croatia's population with an FM radio signal.

We have transmitted radio programming on the FM band since 1957. We have developed and manage the following radio networks with concessions at the national level: HRT HR1, HRT HR2, HRT HR3 and HRT HR (Croatian Radio) locally.

See the table of analogue FM radio transmitters here.

Satellite transmission and reception

Teleport of terrestrial programming to a satellite or reception of a satellite signal for uninterrupted terrestrial transmission.

We transmit terrestrial television and radio programming to Eutelsat 16A from our Satellite Centre at Deanovec.

Using our PlayOut Max and HeadEnd Max, we can convert television and radio programming from other sources (OTT, IP/TV, Cable or HTTP stream) to a DVB-S signal and transmit it to a satellite.

The content that we broadcast by satellite can be received downstream and forwarded for broadcasting via terrestrial signal (DVB-T2 or DAB+ for digital radio) or, as needed, to OTT, IP/TV or cable distribution.

Transmission to Eutelsat 16A is intended for so-called DTH (Direct-to-Home) distribution, i.e., for direct distribution to end-users and distribution to cable distributers.

From OIV's Satellite and Multimedia Centre, equipped with 10 satellite transmission stations with dishes ranging from 2.4 to 7.6 m in diameter and over 20 satellite receiver dishes with diameters of 3.7 m and 2.4 m and with automated de-icing systems installed, we can transmit television and radio programming to any satellite visible from Croatian territory.

Broadcasting to satellites not visible from Croatia's territory (e.g., satellites meant to cover the Americas or Australia) can be done through cooperation with our partners.

Uncoded (free-to-air) radio and television programming can be received by any DVB-S MPEG4 receiver, while coded content requires a DVB-S MPEG4 receiver with a built-in Viaccess decoder module and a decoder card from the relevant television broadcaster.
