This definitely doesn't sit right with me, and it will hurt sales if they move forward with hardware DRM. Is it going to allow me to play content that I purchased physically and ripped? If I can run a ripped version, what stops me from running a friend's ripped version?
Either it will lock people out of their own stuff, or it will be totally useless. I hope for ARM's sake that it's ineffective.
- timthorn 13y agoYes, you can play your own media. What this does is to keep the entire process of media decryption outside of the control envelope available to the (regular) OS, so not only are keys not visible but also decrypted content is also not exposed outside the secure environment. But this is only for encrypted media from a organisation that is using a TrustZone infrastructure - all other media will continue to work as today.
- foobarbazqux 13y agoAt some point the decrypted content has to be exposed outside of a secure environment in order for us to see it. Could you possibly intercept the signals sent to individual pixels, or would you have to actually film your screen?
- georgemcbay 13y agoHDMI out is pretty common on the types of high end phones and tablets that this sort of chip would target. HDCP is long-since broken, so none of this matters to pirates unless the content people also force the device makers to kill HDMI out as a feature which seems untenable. But the pirates are just going to keep ripping the Bluray discs leaked out a month or more prior to retail release anyway since that's even easier. As with the vast majority of DRM, this will only fuck over legitimate users. Pirates will still download the torrent, whether it comes from a Bluray rip, captured HDMI or as a last resort the analog hole.
