We used the ADV7611 in the test of the project. Because we need to verify the HDCP function of the ADV7611, we want to know which register configuration or API is called when the ADV7611 starts the HDCP function.
Correct, -P parts will not de-crypt video.
Are you an HDCP adopter, if so under which company.
We are students, not companies. We are using the ADV7611 to implement the HDCP receiver function.
We cannot sell or help you with keyed ADV7611s unless you are an HDCP adopter. If you purchased a keyless ADV7611-P then you can not verify any HDCP operations. DCP is very strict on this to protect digital content.
Do you have one of our EVAL-ADV7612-7511 reference boards?
Does your university have any affiliation with DCP in any form?
Can we sign the NDA, and then you provide HDCP configuration instructions.
The NDA would require HDCP adoption. Please review our policies about HDCP keyed parts here
Restrictions Relating to the Distribution of HDCP-Enabled Parts
So cannot provide HDCP configuration support？
Turning on the RX HDCP is just a few register writes and readily gleamed from the software manual and scripts. However HDCP authentication will fail unless you have a keyed part. If you have a keyed part and are not an HDCP adopter then you entering territories I have problems answering question on. As a student you have come up against the legal aspects of what you are trying to do. I know this is only a school project but I am still limited.
We now have a chip with a preprogrammed HDCP key. So we just want to verify the HDCP function. Specifically how to enable HDCP. Because the description of the reference manual is not detailed enough.
Thank you for your help.
What is the exact part number off the chip?
Who supplied you this chip?
We only know that the model adv7611, because in your official website saw the datasheet, the datasheet said adv7611 does not distinguish, can use hdcp. So we think it took the key. We don't know who the supplier is. This is because we didn't know who bought it. Only one.
We think we should be able to enable hdcp, if the chip does not have a key, at least we know how to enable it. After the key can be purchased.
The data sheet and web site specify both keyed and non-keyed parts (non-P, -P in part number). Enabling HDCP in a non-keyed part will just respond with a not authenticated indication which will not prove if you are decrypting video correctly.
Keys are programmed directly into the part. Therefore you cannot purchase a key later.
Our chip seems to be no P, but can it be enabled? The exchange of ksv can be observed, but the result will be incorrect. Is this what you mean? Buying with P is to get dcp authorization first?
The 'no P' part has keys. I am getting clarification on exactly how much I can tell non-HDCP adopters beyond what is readily available in the public data sheets and software guides.
If you want to verify functionality of a source regarding HDCP, use a video analyzer that handles HDCP, not the ADV7611.
We just want to try how to enable, not to encrypt and decrypt.
Sorry, wrong. Is with -p.So is it not possible to observe specific things when enabled?
