</div>I don't believe that is correct. I am pretty sure that Firewire's<br>
Digital Transmission Content Protection and Cablecard's Copy Control<br>
Information schemes are separate schemes that don't necessarily match<br>
up. If you have a cablecard-based cable box, then it could possibly<br>
generate the firewire setup based on what cablecard CCI flags are set<br>
(not sure if that would depend on the cable company's implementation,<br>
or the way the cable box is designed). However, I don't think that is<br>
guaranteed to be true. My understanding is that it is possible to have<br>
firewire restricted while cablecard is copy-freely, or vice versa. How<br>
often that happens, I have no idea.<br>

<div>I think that 5C, CCI, and DTCP are all the same thing. They all apply to Firewire and CableCard. The confusion may arise from the fact that multiple acronyms are used to refer to the same thing and it was originally only in place for Firewire.</div>
