The BBC intend to (ab)use the database right to legally restrict the tables. Knowing formats doesn't help in this case. It's a legal problem, not a technical one.

The BBC is saying that it will use Huffman encoding to broadcast the SI tables. This is not a bad idea really, given that it could extend the EPG, for example. The BBC is saying that the table used for this Huffman encoding be "licensed". The problem they have is that it is supposed to be generated from data that is already broadcast, so it should be reasonable easy to recreate this data. You can't claim rights on something that's just a published mathematical function on some specified public data. This is hardly 'copy restriction', it is simply a small data table that a bit of computing power can reproduce. It's not like the data being decoded from the SI isn't going to be in a known format! It's a bit like using a broken condom. And then the second proposal is for an unspecified scrambling system termed in such terms that it so clear that the answer should be "no". 2009/10/6 Dave Crossland <[email protected]> > > Hi, > > Id like to suggest that referring not to 'copy protection' but to 'copy restriction' is... -- Brian Butterworth follow me on twitter: http://twitter.com/briantist web: http://www.ukfree.t...
