Well, one of the things about technology is that sometimes "textbook
technology" which has existed for long only in books or in very
specialised applications (usually defence) just becomes mainstream. Take
COFDM or CDMA.


In the US, much of the pioneering work was done by commercial interests such
as RCA and AT&T. There was good money to be made trafficing messages around
the world!

Now, I don't think there is anything in the specs for a situation where
you would put the same signal twice inside the same DRM transport-stream
(one delayed to the other) and give them both the same streamid, so I
don't know how a receiver would react to that. (some of them will
probably crash :-) )


Perhaps that's something to add in the specs.

But wouldn't a new radio crashing DRM spec make at least some of the new DRM
radios at least partially obselete? If so, that's bad marketing. Once the
radios start selling, they're pretty much stuck with whatever works with all
the DRM radios.

True. My personal opinion is that -concidering the interest of quite a
lot of the big broadcasters- it will succeed, but we will see.


The real decision will be made by the public. In the US, the broadcasters
had a great amount of enthusisiam for AM stereo. There were some radios
offered, but, for the most part, the public didn't care. AM stereo just
never caught on, for whatever reason.

I suppose it's possible that DRM may also be an incomplete success. For
example, the public might find the occasional SW dropouts too annoying, but
they might very much like the improved signal to noise ratio on LW.
