[QUOTE="2old4this, post: 9625, member: 174998"] There is a lot of mis-use of the terminology, so that's the reason for some of your confusion. First, that encryption system everyone will insist on calling "seca" is actually called "Mediaguard". Seca is an acronym for "Société Européenne de Contrôle d'Accès" - the name of the consortium that develops and markets the encryption system. Calling the encryption system by the developer's name also happens with Videoguard. That is often referred to as "NDS" - the owning group). Interestingly, no-one calls Irdeto "Mindport". No-one says they have a "Mindport CAM" or that they are looking for "Mindport keys". So much for consistency... Powervu and MPEG are both different techniques for compressing digital signals. All consumer receivers in Europe use MPEG. Powervu was only to my knowlege used by Scientific Atlanta and is now (only?) used for distribution of signals intended for cable providers. Once again there's confusion here. Most people seem to think that Powervu is the name of an encryption system - it isn't, at least, not primarily. However, Powervu signals can be encrypted or FTA - just like MPEG2 signals - and the encryption system used for Powervu signals is presumably called Powervu too (I don't know of any other term). 2old [/QUOTE]
