would this not be similar to how sky/satellite FTA works with their
subscription cards; scrambled data and the hardware to decrypt it is
kept a trade secret?
You can buy hardware for satellite transmissions (seems a grey area
here, due to possible illegal usage) and it works on mythtv though.
i'm not sure if DRM is used on sky - i know encryption is though.
also, how would the majority of existing customers receive the content
- would they need to upgrade their 1 year old freeview-HD TV as it
will unlikely handle the DRM instructions (i presume hardware decoded
DRM), or would a CI-type device be used? if so, surely it wouldnt be
long before there are drivers available for linux...
asmuch as i dont like DRM, and will actively seek none DRM material
(legally!), i think it's going to end up being implemented by more
companies over the next number of years.
