I read from ADV7441A datasheet that adv7441a has HDCP Decryption Engine.
Can it take the HDMI directly from an BD player?and the the HDMI parts are under NDA.
ADV7441A can come with or without keys. To buy it with keys, you must be an HDCP licensee. In that case, yes it will decode HDMI directly from a BD player. The version without keys will not, but anyone can buy it.
The ADV7441A is no longer under NDA, all the docs are available. However, you still cannot buy a part with HDCP keys unless you are an HDCP licensee.
Thank you for your explanation.
If we purchase license and the version with HDCP keys,does it need any more set of other register?or can directly decrypt the HDMI under NDA?
There is no NDA, I'm not sure what you are referring to.
If you are an HDCP licensee, you can buy parts with keys and they become your responsibility under that license. The license is not with ADI, it's with DCP, LLC. You certainly would need to develop software to control the ADV7441A, there are register setting scripts, and documentation on the ADV7441A available on the FAQ section of this forum.
