Multimedia, AV If the rumours are true, and if this Pastebin post (be sure to mirror the key if that won't get you in trouble with your authorities) is legitimate, then it looks like High-bandwidth Digital Content Protection has been cracked so hard its mother's mother felt it. HDCP is a copy protection mechanism which protects the audio and video streams sent over DisplayPort, HDMI, and DVI.

It's been a while since I read anything about this, but at some point in time there were people saying that HDCP would prevent a High Definition data stream from playing on Linux, because the Video drivers had to support HDCP.

I think that was AACS, not HDCP. Certain high definition videos are encrypted with AACS to stop them from being played on "unauthorized" devices. HDCP is used by the OS/video drivers/movie players to prevent you from recording the output of your monitor the video with a TV tuner. So, Linux has always been able to display high definitions, you just can't play encrypted movies unless you have the AACS key.

In other words, if you use an "authorized" OS, you have to worry about having an HDCP monitor, and AACS is irrelevant since it is handled by the OS.

If you have an "unauthorized" OS, then HDCP is irrelevant, and you have to worry about having the AACS keys to decrypt the movie.
