HDCP V2.x
The 2.x version of HDCP is not a continuation of HDCPv1, and is rather a completely different link protection. While all of the HDCP v1.x specifications support backwards compatibility to previous versions of the specification, HDCPv2 devices may interface with HDCPv1 hardware only by natively supporting HDCPv1, or by using a dedicated converter device. As a result, there is currently no deployment plan for v2 to replace v1 in existing systems. This means that HDCPv2 is only applicable to new technologies. It has been selected for the WirelessHD and Miracast (formerly WiFi Display) standards.
There are still few commonalities between HDCP v2 and v1
- Both are under DCP LLC authority
- Both share same license agreement, compliance rules and robustness rules
- Both share same revocation system and same device ID formats
