[quote]Much of what Microsoft had to do should become apparent once they release their CableCARD compatibly verification tool. The tool, announced at the same time as the rest of the CableCARD announcement, will check whether a PC can “support the solution” so that PC owners can confirm ahead of time whether they’ll be able to use a CableCARD tuner with their PC. Clearly this is some kind of DRM verification cool, but we’re in the dark in the moment as to what it’s going to be checking for. Given the paranoia over at CableLabs, our best guess is that they’re looking to have CableCARD equipped systems locked down similarly to Blu-Ray – this would entail the use of PBDA to securely deliver the stream, and HDCP as an output requirement, with the verification tool checking for all of this.[/quote]
It looks like there will be a validation tool a lot like the tool we saw from Cyberlink that tells you if your system is ready for Blu-ray playback.
