DRM Minimum Receiver Requirements (MRR) Published

DRM Minimum Receiver Requirements (MRR) Published

The DRM Consortium’s Technical Committee has completed the technical requirements for receivers designed for the DRM system below 30 MHz. This Minimum Receiver Requirement (MRR) document describes the minimum performance required for the technical parameters that provide a fully functioning DRM receiver. A second phase of work will extend the document to detail the figures for DRM+ receivers too.

“We have taken account of the real world environment in which DRM receivers will operate” says Frank Hofmann of Robert Bosch, who led the team writing the document. “That means ensuring that the receivers will not only work well if they meet all the requirements, but will also be cost effective to manufacture.” The MRR document is an important basis for receiver manufacturers and will be available to everybody.

The DRM Technical Committee has also completed work revising the Multiplex Distribution Interface (MDI) and Receiver Status and Control Interface (RSCI) standards to include DRM+. “We wanted to make sure we had captured everything in these revisions, so we waited a little while after publication of the extension to the DRM System Specification last summer” said Lindsay Cornell, Chairman of the Technical Committee. “We wanted to get some experience of DRM+ transmissions.” The MDI and RSCI specifications have been approved for release from DRM to ETSI for consideration and publication.

The finalised MRR document will be presented to the DRM General Assembly this week and then published on the DRM website for easy access. The Annual General Assembly of the DRM Consortium will be held at the headquarters of Radio Netherlands Worldwide (RNW) on 24th and 25th of March in Hilversum, Netherlands. The DRM General Assembly is attended by DRM full and associate members and it is the largest decision making body of the Consortium.
