I'm a beginner in sattelite forum, but i'm an electronic engineer with expert in computer. I want study full theory of viaccess and irdeto and other scrambling method. what r best references in these fileds?
Look in the respective forums on this board. You'll find links to documents and FAQs on each of those systems. But don't expect too much detail. The best detail is on the Irdeto system, where the full patents are also published. But the rest is just pieced together by interested hobbyists.
