Abstract
Digital Radio Mondiale (http://www.drm.org) is a new system for digital broadcasting below 30MHz. The DRM Consortium has now completed work on the technical standard which describes the "Signal on Air". This is an open standard which has now been published by ETSI as a Technical Specification, and it is currently being input to the ITU/IEC standardisation process. As for any open standard, it is vital that any party implementing the specification should interpret it in the same way.

This document summarises the "Compliance Testing and Specification Validation" exercise conducted within DRM. This has now successfully demonstrated that the DRM specification is clear, complete and unambiguous. The exercise was led by BBC Research and Development, drawing on our experience of validating the DVB-T specification in the successful VALIDATE project.
