DRM RADIOS AND EQUIPMENT

Note to the Manufacturers of DRM equipment

Equipment implementing the coding and modulation part of DRM requires the use of certain essential patents for which manufacturers need to make agreements with the patent holders.  The audio part of DRM falls entirely within the licencing of AAC undertaken by Via Licensing, a Licensing Administrator acting on behalf of the AAC licensor patent pool – see www.vialicensing.com.  The DRM Association and the DRM Consortium do not make any charges for the use of the DRM technology.

DRM RECEIVERS – AN UPDATE

(as of 22 June 2020)

GOSPELL DIGITAL TECHNOLOGY CO LTD, CHINA

 

Gospell Digital Technology Co Ltd. first developed the DRM standalone Receiver GR 216 pictured left.

 

Now there are three more portable radios: GR- 224, GR-226 and GR-228

 

The Gospell receivers support all DRM frequency bands (AM and FM), using the latest audio codec xHE-AAC (for exceptional music and speech sound), as well as the advanced text feature called Journaline as well as the Emergency Warning (EWF) functionality.

 

The company is waiting for substantial orders. The price per unit will be reduced based on volume produced.

The automobile receiver industry in India is already on board and has invested millions of dollars in the development of DRM digital radio capable receivers and the roll-out of DRM equipped cars is growing quickly by the month reaching over 2 million by now (May 2020)

Car manufacturers which have so far incorporated DRM digital receivers in their models in India are Hyundai, Maruti-Suzuki, Mahindra, GM Motors and lately Toyota.  More international car brands are planning or are in the process to fit DRM digital receivers in their vehicles. OEMs use chips from various manufacturers, such as NXP, Silabs and others.

NXP

 

One of the largest automotive chipset manufacturers in the world, based in the Netherlands, has recently showcased a new DRM solution for car OEMs during the New Delhi BES Conference and Expo 2020.

 

It has added FM support to AM, Journaline advanced text, and the xHE-AAC audio codec for music and speech.

 

In addition, NXP demonstrated at BES 2020 dual tuners and a cost-effective single tuner on DRM platforms shown above. These tuners also support the traditional analogue frequencies.

Gospell

 

Gospell in China has recently developed car solutions:

 

a. The OEM device GR-5018CW
b. The after-market device GR-502 BCW. This unit will enable the cars already on road to
DRM digital reception.
c. The DRM car adaptor GR-227

RF2Digital

 

RF2Digital is a South Korean company with a presence also in Germany. It has shown an SDR based dual automotive receiver solution for full DRM during the 2020 BES Expo in Delhi. The solution, still under development, gives a fast time-to-audio and fast scan function as well as other DRM features. The future product will give a much better experience to automotive users.
