So, what can we do with this info?
Well, for decrypting Blu-Ray we do not need it, since the above decrypts the transmission.
What the people of the world could do is make a Blu-Ray player that doesn't need to be licensed. Put in a chip that decodes stuff using this matrix and you can play the blu-ray anytime, anywhere on to anything.
HDMI to component is very much possible now. Anything that is eventually HDMI can now be used for anything now.
