An enhanced DAB radio product for broadcasters transitioning from FM to national digital radio systems is being demonstrated by GatesAir. The company has created a dual EDI interface for networks using Maxiva VAX VHF transmitters, with seamless switching between main and backup paths across networked DAB contribution and distribution architectures. The system can provide new layer of redundancy across expansive DAB transmitter networks.
As EDI is an IP-based transport system, broadcasters can take advantage of lower program delivery costs and greater multipoint flexibility, said GatesAir. Dual EDI inputs are integrated with Maxiva VAX transmitters, seamlessly linking third-party DAB headend and multiplexers with Maxiva exciters to further accelerate DAB network deployments.
