DRM is starting on the long road of general acceptance just as DAB started some years ago. DRM is a very advanced technology using state of the art audio encoding technology but it is not well understand. The DRM Handbook is written for a wide audience from those who want to decide whether to invest in a receiver to those who are more technical and want to understand what is â€˜under the hoodâ€™.
