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

GOSPELL DIGITAL TECHNOLOGY CO LTD, CHINA

 

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

 

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.

AVION – DRM RECEIVER BY COMMUNICATIONS SYSTEMS INC, INDIA

 

Communications Systems Inc. has upgraded its Avion DRM digital receiver AV-1401 by incorporating several enhancements, like improved sensitivity, Emergency Warning Functionality (EWF), with provision to switch on the receiver automatically when EWF signals are being received.  The company sells its product on Amazon India: at a reduced price per unit:  9255 Rupees (approx. $120) including shipping costs. The unit price, when ordering directly from Communications Systems Inc., is further reduced to 7790 Rupees (approx. $100), including taxes but shipping costs excluded.

The company is expecting substantial orders which will reduce price further due to increased volume.
