Today we explore some of the recent news from HD Radio™ technology as well as Digital Radio Mondiale (DRM) at the Consumer Electronics Show in Las Vegas (just concluded) as well as the India AutoExpo. Both technologies have some news on the regulatory front. Vatican Radio also just completed a DRM+ over-the-air trial as well.
Both DRM and HD Radio technologies made big splashes at CES. iBiquity President/CEO Bob Struble called this year’s CES “the best ever” for HD Radio technology and showed the latest automobiles with HD Radio receivers, and 60 new consumer receivers also featuring the technology. Twenty-two auto brands feature it, and 2 of the 3 major US manufacturers (Ford and GM) have HD Radio receivers in at least some of their models.
In New Delhi, Delphi, a leading manufacturer of automotive products showed a DRM car receiver with the NXP chip at the AutoExpo earlier in January.
Vatican Radio trialed DRM+ over-the-air in one of the most dense radio markets in the world during December and early January. A Nautel VS1 FM/DRM+ transmitter and VS-DRM digital exciter were fed by an RFmondial modulator and Fraunhofer R4 Content-Server. Official measurements and results are not available as of press time, but early indications are that the trial went well. The transmission was into a combined antenna system normally used by Vatican Radio for one of its FM radio stations. The equipment is now on its way to India where it will be shown in February at the Broadcast Engineering Society annual show in New Delhi.
The DRM Consortium also announced that the International Telecommunications Union (ITU) has endorsed the extension of DRM as a global standard. DRM+ is now official, and includes all frequencies above 30 MHz in the VHF band. Full story with technical attachments is here.
