This idea just came to my head now.
Why does Pay TV companies, ie sky issue smartcards?
Surely it would be more easier, to prevent card sharing, and possible borrowing of a sky card, if the encryption was inbuilt into the STB, for example an NDS chip located internally.
South Africa has a platform (M-net) launched in 1985, due to the delay in shutting off Analogue there, the 1985 M-net terrestrial service is still broadcasting, although most people have gone over to the Digital DStv platform now.
The point is, although the video only has a minor scrambling to it, the audio is super secure, and not many people have been able to actually crack it, those who have, have either been caught by Multichoice, or are laying low, but it's a big task, and this is 30 year old Technology. The equipment may have been slightly upgraded, but I'm pretty sure most of the equipment used is still the original equipment.
How many times has the current NDS system actually successfully cracked internationally?
If not cracked, all the millions of card shares going on.
If there is internal based encryption, and secure enough, and it's only available on certain decoders, and enforced strictly, card sharing should become a thing of the past.
What do you guys think?
