Dude up north Great question Yor question shows yo definatly following this heated action between PTA and pay satellite service
Current FTA receivers like CW, VS, SV, CS and many others can support more than one conditional access in the MPEG-2 so even if DN and BEV use 2 different security providers current FTA receivers can definatly decrypt.
Lately I'm observing strong indications DN and BEV will have 2 different securities I strongly believe N2/N3 is better than any other security in the market not sure breach of security was due to leak or just clever back engineered by coders As a wild guess I would say brelient back engineering more than leak cuz even if it was a leak it still has to be modified and back engineered for cardless FTA receivers Nagra*vision also owns Media*guard Which I'm sure they have shared many drawing diagrams to stand against PTA
DN can definatly change security providers but many receivers out there about 10 years old can not work the way they would want it by simple card swap and even if they change receivers no security provider will ever guarntee full security
See I only cheer for the good play Right now PTA owns pay satellites My quest is for how long?
