The details are to be found in an article written by Matthew Phillips, the vice president of global marketing for CML Microcircuits Ltd, a fabless semiconductor supplier located in the United Kingdom. He is also a member of the steering board of the DRM Consortium and a member of the IET.

The explosive growth in embedded IoT devices and the burgeoning market for wearables have driven massive innovation in digital audio electronic components such as digital signal processors, (DSP), digital-to-analogue converters, (DACs) and System-on-Chip, (SoC) technologies. The low-cost, and low-power consumption of these advanced devices have combined to make compact receiver modules available, such as the DRM1000 by CML Microcircuits and Cambridge Consultants.
