</blockquote></div>Not really...<br><br>You can compare them.<br><br>IP content payload is a superset of the payload of DVB. So IP can carry the same stuff that DVB can.<br><br>True different carrier protocols (methods), but that is not that relevant, since you have IP broadcasting technologies, which are similar to TV channels, that is you somehow enumerate content streams. The fact that they can be personalised, is irrelevant.
<br><br>The only true difference in the context of 'preventing piracy', which is what DRM is supposedly about, is that using IP it is easier to setup an automatic retransmission. That's all.<br><br>Any computer with a DVB/T card bout over the counter, using off-the-shelf software for any OS can be set-up to record and/or retransmit the recieved content over IP. uknova? isn't that a proof that it is possible?
<br><br>It is (nearly) the same argument as the analogue hole in DRM. The technologies differ, but the pattern is the same.<br><br>DRM is broken and breakable by design:<br>* it is not a protection against piracy - since the circumvention of all currently known forms is trivial
<br>* it puts a presumption like - everyone is a possible offender ( pirate ) - is that ethical?<br>in the BBC iPlayer case the ethical arguments go further as Steve puts them<br> so eloquently:<br>* the technology used is not open to third party implementations -
i.e. a tie in to one vendor. If they used a DRM which is open, that is anyone can have the knowledge to implement it, then there would be no technical or 'public contract' problem. a player would very soon exist on all platforms. The ethical issues will still exist, but that is yet another fight....
<br><br>BBC does have licensing and revenue issues - DVD issues, licesing to foreign brodcasters, BBC America.... Well they have to deal with it one way or another. Unfortunately somebody there made the wrong choice. Restricting access by UK IP, individual watermarking, TV license number based access are a few alternative approaches that spring to mind without having to strain my brains too much
