Pretty sure; by my reading (and Robert's I think) of CENELEC EN50221, you feed an encrypted stream to the CAM module, and it outputs a decrypted stream. The CAM is treated as a "black box"; you just send control signals at it to choose which PIDs to decode etc... well, I'll find out if who is right in a few days :) Incidentally (for those of us in the UK), I just found a company that is moving back into the encrypted DVB-T market: http://www.topuptv.com Specifically from their site: "IDTV â is an Integrated Digital Television that has the set top box already built in and that means the TV can receive the Freeview channels. Most of the IDTVâs do not have a viewing card slot but have a âCommon Interfaceâ slot for the special Top Up TV âCAMâ. The Top Up TV Viewing Card then fits into the âConditional Access Moduleâ (âCAMâ). There a few TVâs that have been made with a viewing card slot built in and so please check your instruction manual to see whether your TV has this feature or not." I wonder how long it'll be before we start seeing DVB-T cards with CI interfaces in the UK.... -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe linux-dvb" as subject.
