What is OIV DAB+ Digital Radio?

Digital radio for new content and interconnected listeners

OIV DAB+ Digital Radio is a platform to air a DAB+ (Digital Audio Broadcasting) radio signal which offers listeners the possibility of receiving a radio signal without interference, and gives broadcasters a greater selection of programming with clear audio quality and additional text and graphic services that accompany the audio content.

Technical information

DAB+ transmission

The VHF (very high frequency) range from 174 to 240 MHz is used to transmit DAB+. Since this is a digital network that is based on OFDM (orthogonal frequency-division multiplexing), operation in the SFN(single frequency network) has been enabled, i.e.,transmission in a single frequency in a single region or an entire country.

Coding audio signals

AAC+ (high-efficiency advanced audio coding) is used to code audio signals.The usable capacity of the multiplex or ensemble is a maximum of 1.5Mbps, and an average of 1152kbps. Given that audio programming employs different coding speeds and degrees of protection, the occupancy of the multiplex is computed by capacity units, of which there are a total of 864.

For example, with an average speed of 64kbps and an average level of protection, roughly 15 audio channels fit into a single multiplex. This is in fact the greatest advantage of digital broadcasting; space for a higher number of channels, but given the broad array of services that it offers, DAB is much more than digitized audio programming.
