High-Bandwidth Digital Content Protection better known by its acronym HDCP, may have been compromised according to claims from net sources. Details on how and who leaked the master key have not yet surfaced.

HDCP was invented by Intel to be a cheap-to-implement, high-performance cryptographic system suitable for use in audio and video applications. Its purpose was to create a secure digital path that could not be eavesdropped, so that pirates would not be able to make high-quality digital copies of high-definition video. HDCP also provides a mechanism for key revocation: if a device's key has been leaked, it can be added to a list of revoked keys, effectively blacklisting it and preventing it from being used for playback of encrypted content.

HDCP is just DRM that makes using older devices with newer ones a pain in the butt.
 
And forces people to buy new equipment. It should have been illegal from the start to do this.
 
HDCP like Macrovision is a pain in the ass for legit consumers, and no hindrance for those who want to make high quality digital copies of high def videos.

This is going to make video capturing (legal use of course, consoles and such) a lot easier and affordable, hopefully.
 
Wow!

I thought the thread title was HARD-OCP Master key compromised! Who knows what that could have unlocked!

Haha I read 'HardOCP Key Master May Have Been Compromised' and thought 'Did the Stay Puft Marshmallow Man get Kyle??'

The Stay Puft Marshmallow man better pack a lunch.. i dont think Kyle would be an easy or quick fight to drag him away from his Eyefinity setup..
 
Ya fuck the people that made this up in the first place. I got a high end Denon reciever, a high end Denon DVD player and a 1080p Mitsubishi RP-CRT. The reciever will turn all inputs whether analog or digital into 1080p HDMI which is great because I only need to use 1 input on the TV.

Problem is, my DVD player will not play nice with the TV going through the reciever if I want to use the HDMI because the TV uses DVI and came out just before HDCP was mainstream. Everything else works fine though, PS3 doesn't care, other stuff doesn't care.

Would be nice to have a dongle that could strip the HDCP to make devices "universal", but you saw how quick Sony trounced on that hack of the PS3.....an entire orginazation could probably send a hit squad.
 
I've hated HDCP (I about said "DHCP") ever since my Onkyo TX-SR605 decided it only wanted to handshake with my other devices (cable box; 360) whenever it feels like it, which is one in about every five times I turn it on. I plug my devices straight into the TV and they work, into the receiver and nothin' because HDCP isn't talking.

But as we see, HDCP has really been working well... says my WMV-HD collection.
 
My DVR box from the cable company (SA 8300HD) will not work through any kind of switching source whatsoever. It puts up the "you are trying to be a thief" screen if it's not connected directly to the TV.

Supposedly, with the "leaked" PS3 service manual that's floating around on the internetz one could find out how to get HDCP-free signals out of the PS3.

If this is true, that'll all be a thing of the past.

hahaha.. I read the same thing at a short glance, and double taked at it. Lols. =) The tricks the human mind plays on it self. Sigh...

:D
 
To put it simply, HDCP prevents you from making high-quality (higher than 480i) copies of video from the video ports in your video card or other video source.

HDCP: the DRM that prevents you from doing something that nobody wants to do!

Spoken like a true MPAA @sshole.

A friend of mine has a plasma TV without HDCP (component only). His DVD, BluRay players all downgrade to 480p. In order for him to watch 1080i he has to rip the media, thus stripping off the copy protection.

True, but it would have been used from day one, til bluray was cracked, by the commercial counterfieters had it not been implemented. Of course other ways were found around it anyway that made the whole thing an expensive waste.
 
Looking at the Engadget link, they link to this earlier version device that's supposed to strip HDCP and output to RGB, Component, and the like:

Not exactly cheap, but for high-end pre HDCP folks, it might be worth it.

Those devices have existed for a while, the problem was that because keys are updated with every Blue-Ray disc you could pop in the latest movie and be up shits creek because the disc banned that device. It's happened to a couple of devices over the years.

What likely happened was what was a researcher predicted when HDCP was new, as more and more devices with problems were found and banned, enough info would be discovered that would make the master key guessable and if I recall right he figured it would be guessable after around 50 devices were banned. Guess that happened, or enough keys were secretly collected for them to figure it out.
 
I FREAKIN LOVE how everything FAILS before it even exists :p Is it not a simple sign by now? Just give up, you can't beat the rest of the world.

It did not fail for a while actually. Though that was prolly more due to there being multiple, better, and more convenient ways around copying any content involved, rather than the difficulty required to hack through it.
 
Reading around its been confirmed this is the real key game over
 
Any word on how the key was discovered? Cryptanalysis, or a leak, or... ?
 
its about time. i hate stupid drm. such a pain to by-pass. if they broke the master key, should make life easier
 
HDCP really needs to go. If HDCP were gone, I am certain the virtully no piracy would take place by tapping an HDMI port.

I hate the idea of DRM and copy protection, but functionally don't typically have problems with it. There were however 18 months worth of consumer electronics that had compatibility and handshake issues before this got sorted out. There are still problems, but most consumers don't notice on the newer generations of electronics.

Lets also not forget about the "HDCP ready" video cards that we were sold for years that didn't actually support HDCP and the price premium on the first cards that actually did support HDCP.
 
well HDCP strippers also made this tech useless to begin with

the most annoying thing was not being able to play HD video on older non-HDMI TVs because of this stupid tech...drove me nuts

Tep thats what I was getting at earlier, the short DVI boom got screwed in the long run. And HDMI is awsome because its just one simple cable....and now I'm seeing they have Video+Audio+Ethernet HDMI.....damn can't wait till they get Power in their as well.

120v AC running within the same cable as data isn't going to work well. You'll generate a lot of noise on the data lines that way (quite possibly enough noise to knock bits out and degrade the transmission).
 
Running 120v power through cables adds all kinds of new laws and regulations. I doubt it would happen.
 
Most items you'd want to power via hdmi only need low voltage DC. A scheme along the lines of PoE could potentially be used over HDMI and could probably be made to deliver enough power for at least a medium sized display. I'm not sure if there are any plans to actually do it, but it's a logical thing to try do I bet there are, even if it means changing the cable and connector.
 
...and in other news, the MPAA has just announced their support for the brand new "Green-Ray" media, the successor to Blu-Ray offering a staggering 51GB per disc and 1085p video. Compatible players are expected to hit the market christmas 2010 for $1599.99.

*player is not compatible with HDMI, requires HDUMBI support to function.
