You need more practise at paraphrasing, or more care when trying to
summarise other peoples' points of view. I never said any such thing;
provide citations and don't verbal people, it's poor manners.

Yes to RFID - if we're talking about hostile tracking of active tags,
compilation of invasive databases of individuals' purchases, the
referral of all tag queries back to a US root server, etc. And evil
applications for DRM exist now. They haven't been fully implemented in
consumer video yet - but the industry has a strong move in that
direction, which was my point.

Don't shout. I'm deaf on the right, but I can read. The relationship is
quite straightforward. The developers of the DVB standard are working on
DRM. We already have an example of DRM making existing consumer
electronics obsolete: HDMI, which if in the DVD player would decline to
play back in high-definition without an HDMI interface on the TV.
This is partly conjectural, I agree. The standard may not be developed,
or it may not be adopted. But the intention is there; and my argument
was merely that the digitisation of the signal is an important enabler
to the DRM; that is, without the digitised transmission, you can't apply
digital DRM to the signal.
I would even argue that there is a similarity of intent between this
sort of development and RFID. They are or can easily become anti-consumer.
And there is, in fact, a current DRM buried in the Digital TV world:
DTCP (Digital Transmission Control Protection). So the relationship
between DVB and DRM is not so hypothetical that it should be ignored.
