How is Moome passing HDCP compliance? Are these cards truly HDCP compliant? I though HDCP does not allow analog output. Yes you would have to modify the projector to access it but since service manuals for these older CRT projectors are widely available, this is a no brainer. Pulling HD analog out from one of these cards is a piece of cake. Far easier then dealing with digtal video data busses.

My guess is they are HDCP compliant as long as the image constraint token is not turned on. If it is they stop working? Just as BluRay players will output compoonet analog as long as the constraint token is not set.

The cards are fully HDCP compliant, AFAIK, on all sources I have tested (BR, DVD, Cable) with my G70.

I have never had an issue running HDMI from Blu-Ray player to Moome HDMI card..
The Moome cards are 100% compliant with HDCP....

Input cards are covered in a subsection of the license requirements. As long as they have screws to secure them, they are OK.

I really doubt Moome has "licensed" anything to make these cards (which is precisely why they exist today).

It could be the chip maker who is responsible for the license.

You can get any chips you want to find, licensed or not. Do a google search for any of the HDCP DVI chips and you can find sources. Usually, the chips were destined to go in another device, but didn't make it for one reason or another. As long as you buy in some volume, the vendor will accommodate.

I'm not saying that this is what Moome is doing... but China is a hot spot for acquiring such chips. I have imported many hard to find components.

Also, most rear projection CRT's that were released from Mits, Sony, and others with DVI and HDMI use similar boards that are internal. But it's the same thing, a DVI board that plugs into another board. The DVI boards from manufacturers are no different in design than Moome's.

They don't have a choice. It's not just a legal issue but a technical issue as well. If the material is HDCP encrypted, the device manufacture using the chip set must have software keys. The chip manufacture, Silicon Image, holds these keys. As for off shore gray market chips, that won't work either. Yes a foreign IC manufcature could make an HDMI interface chip. But it won't contain valid HDCP keys and threrfore cannot be HDCP compliant.

The post about the "screws" is probably correct. An exception was probably made in the licensing for legacy CRT projectors.

But be assured, HDCP compliance is not something that is optional for a manufacture. Besides the legal requirements, they have to have the software keys to decrypt and lacking those keys, the interface won't work with HDCP.
