ADI’s Blackfin processor based DRM radio was one of the first designs that met all Minimum Receiver Requirements (MRR) stipulated by the DRM standards. The success can be attributed to an excellent team where ADI managed and partnered with BBC in UK, Dolby (erstwhile Coding Technologies), Deutsch Welle and AFG Engineering in Germany. The technology and reference design was then adopted by manufacturers to engineer and make products. Now, a few other companies are in process of using this design for making digital radios in India as well.
