How does HDCP work over DisplayPort? I guess HDCP is a different spec from HDMI itself?

- Dagonfly 11mo agoYes, HDCP is seperate from HDMI and DP. The source and the sink need a HDCP-licence. Both devices have embbed keys that get exchanged to estabish a encrypted channel. Without the licence you can't get the required key material. AFAIK, you can even sell HDMI devices without HDCP. Practically though, every entertainment device needs HDCP support.
