Hmm, someone point out where my logic fails here ...
* It's OK for the stuff on FireWire (or the new ethernet option) to
be encrypted because a TV set manufacturer can decrypt it.
* The cable network uses common standards - at least I imagine the
cable companies are too tight to pay to have their own proprietary
kit made (I assume a lot of it is common and just has their name on
* Some TVs have cable tuners/decoders.
So in theory it should be possible for a standard TV to tune,
decrypt, and decode off-the-cable signals. Though I guess it would
need a slot for a subscription card.
At which point the penny drops - the cable companies probably won't
release a CI module as they'd rather make their subscribers pay over
and over again for a grotty decoder box.
