Actually, from my understanding this is going to be much more complex than this. It's actually pretty hard for a _card_ to follow the broadcast flag rule. What makes more sense is a _system_ that enforces the broadcast flag rules, of which the card is a part. However, to do that, the card does have to do one thing, namely refuse to work with associated software that hasn't been blessed as following the rules. Or be a very smart card so the whole system is in the card. To do this, the card could, for example, only produce encrypted streams when the BF is set. Your could read from the card but all you would get was encrypted data. Unless your software had the keys, it could not play it. Your software would need to prove it was "well behaved" to to keymaster in order to get a key. That's actually tough, because software on an open PC can be reverse engineered and keys extracted. And open source software is out of the question, unless it had a locked, proprietary module for all playback or output of video. In theory, the card could be blessed and encrypt using the hdcp protocols, and the software might simply stream out this data to your TV, which if it's new, will have the HDCP keys inside. I don't know what actual vendors are planning. Another theoretical possibility would be a card that put out encrypted streams, and you fed the streams back into the card for it to feed out via QAM or ATSC or an encrypted protocol like DTVLink or HDCP to your TV, where it decrypted them. I think that's supposed to be legal but the rules are arcane. However, even if this were made to work and were legal, in these cases you can't do OSD, you can't do commercial elimination, cutlist editing, preview windows and so on. Plus the card now has to be a lot more expensive compared to a raw demodulator/tuner.
