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 RNW in Hilversum on 24 and 25 March. The DRM General Assembly is attended by DRM full and associate members and it is the largest decision making body of the Consortium.

It’s hard to get enthusiastic about this. By now, DRM is too little too late, so I think the consortium publishing this information is largely academic.
You’ve got to hand it to them, though. They certainly wrote the book on tenacity. I wish them luck, but I have strong doubts about their success.

This is even to late, am, fm, dab+,drm ,drm+ broadcasting. all this will be replaced by Iphone pocket phone web radio.. Free of costs for all users.No costs of downloading, free subscribtion Unlimited numbers of listners per station..Works everywhere, even on the sea, the desert.
Have one question to all of you, why are broadcasters willing to bid so much on a radio frequency for broadcasting????
on Mar 23rd, 2010 at 17:07
The bidding is for reasons that FM (AM) will be the dominant broadcasting platform for the next years, might even be 10 years or more.
Whenever any form of digital broadcasting will have penetrated well, FM will loose it’s value.

Hi Ruud, correct, but if we replace the dab+ with drm+ instead in all bands of band l, ll, lll we will have 2 standards. DRM and DRM+.
Keep the long and mediumwave in AM, but use the SW to DRM and the rest to drm+.
Let us see the applications of digital radio in Sweden after 14 of June.

how can you write “all this will be replaced by Iphone pocket phone web radio.. Free of costs for all users.No costs of downloading”? To use that, u need to pay an ISP, ISP are not charity, they are for profit.

The Iphone has been sold in 500.000 pcs in a half year in Sweden. I read in Radioassistance Norway that listning to radio in the 3G net cost 3 time more than via a national am/dab+ network. people belive in this and are willing to pay for it, even if normal AM/FM/DAB+/DRM/DRM+ is cheaper to listen too an better.
When the Radio Authority release the dab+ licences, there will be lot of webb radio stations asking for a licence to get more listner.
Lets the future show us the winners, webb radio or broadcasters in the broadcasting bands???
Needs a 10.000 servers to get listners and advertisers.
