Coincidentally I was asked yesterday whether it would be possible to distribute video from a satellite STB via a wired home network. I read up on MythTV and various other solutions to streaming video, then realised the STB has an HDMI output. Ouch, I thought, that's the end of that - for protected HD streams anyway.
But today things have changed: it's now possible (in principle) to build a HDMI video capture card, or an HDCP stripper out of an FPGA.
Most of the discussion here assumes people with use the key for ripping/piracy but I think opening up media streaming to HDMI sources is the most important breakthrough. Although HDCP strippers do alread exist (e.g. HDfury) they must rely on black market parts (buying HDMI silicon requires signatures on legal agreements). I am going to tell my friend that my answer to his question just changed from "no" to "sometime soon". (Assuming I can come up with a real time encoding solution, which will probably not be trivial...)
I never could see why the content protection agenda needed to include restrictions on how you wire up your video sources and displays, and am glad that part of it has been defeated.
