[ADV7480] Management of the key (BKSV) for HDCP authentication

Question

Hi, 
 The customer has asked the following question, so please let us know. 
 The ADV7480 has an HDCP authentication key (BKSV) written into it, but is it necessary to link and manage this key with the product? 
 Customer checked the HDCP specifications but could not find any relevant description. Is that the rule with DTCP LLC? 
 Also, are you linking the IC serial number with the key (KSV)? 
 Best regards.

 Yes, Each part has internally stored key so we cannot change the key. 
 You need to be an HDCP adopter before you can purchase the keyed HDMI receivers. 
 Please check Digital Content Protection for more information on HDCP licensing. 
 Kindly note that, -P option specifies a non-keyed part and HDCP licensing is not mandatory for -P part. 
 Note: For HDCP, before we sell keyed receivers we verify the customer is an HDCP adopter but you do not need to be an HDCP adopter to purchase HDMI transmitters. This is ADI's policy and was generated in conjunction with our lawyers and DCP. Please review http://www.digital-cp.com/ for any licensing concerns. 
 Thanks,
