Is there a box that legally strips HDCP to go into something like a Folsom Image Pro HD? The Image Pro has DVI without HDCP.

Thanks

No. The whole point of HDCP is that it's a corrupt anti-consumer racket, and they change the laws to make it illegal to decrypt the signal without playing by their rules. (That doesn't mean people don't do it, but it's technically illegal in most places.)

So then there is no way to show, lets say Blu Ray, on a Barco HD18 which has DVI (Non HDCP) or HD-SDI inputs and keep the signal digital right?

Have your player modded to add an HD-SDI output. Problem solved and no HDCP handshake issues.

Are there any legal issues with this?

Who Cares!

There are no legal issues if no one else knows so don't tell us.

Fine line. But as stated above, the HDCP police aren't going to storm your house if you have one.

I'm no lawyer or DMCA expert but as I understand it, circumventing copy protection in any way is a voilation. HDSDI does circumvent the copy protection. However if you goal is to only view the material you legally purchased on a legacy analog projector, then you could have a strong case to legally do it.

Now as an EE I do know this. HDCP requires that compliant products are to have no exposed un-encrypted data busses yet at least one company I know of offers HDSDI modified players. So how are these players HDCP compliant if the third party can get to the un-encrypted data busses?

Seems that player manufactures aren't playing by the rules either!

I can't guarantee this is legal, but it appears to have proper licenses, etc.:

I can't provide any personal experience with it, but it seems to have gotten a lot of good reports for initial users.

There is a legal issue, but a lot of it depends on how you utilize it. End-users will not likely get caught since your not doing anything but viewing movies. How can they tell who is or who is not using a HDCP stripper.

That said, if you decide to pirate films, they'll probably catch you for pirating and distribution.

I would recommend looking for a user called "moome" in the for sale display sections for a good alternative for those with this issue.

This strips HDCP and outputs RGB. So it's not legal. There are no legal devices that strip HDCP output a non-encrypted signal, digital or analog. If you must remain legal, you are SOL.

There's a distribution amplifier called the Dtronics DD-D12 that takes a HDCP encrypted DVI source, decrypts the HDCP, and outputs unencrpted DVI that will work with your display. It's no longer in production but it does turn up on Ebay now and again, typically going for $400-$600. I have a couple and can testify that it does work.
