It can be implemented to work over DVI, DisplayPort, USB, and more. If you've ever hooked up gear and gotten a blank screen (or turned on gear in the wrong order and gotten a blank screen), this HDCP 'handshake' is usually the issue. The source and the sink need to be in agreement, understanding their keys, or no content gets transferred. Enabled repeaters, like receivers, can be in the chain as well. It does this by creating encrypted keys between the source and the display (called the sink). HDCP doesn't care what goes across the cable, as long as that cable is secure. DRM, the encryption of the content itself, is a separate issue.

Ostensibly this is so you can't take the output from a source (a Blu-ray player, say) and plug it into some kind of recorder, to make a copy of the content. It's designed to create a secure connection between a source and a display. HDCP 2.2 is the latest evolution of copy protection. Back then it was called Macrovision, which evolved to CSS for DVD and finally HDCP, which stands for High-bandwidth digital Content Protection, for Blu-ray players and HDTV devices like satellite and cable boxes.

So it's possible that the 4K TV you bought last year, or even the receiver you buy this year, might not be able to receive/pass all future 4K content. The next generation of content protection is called HDCP 2.2, and not only is it not backwards compatible, many new 4K devices don't even support it. Thought all you needed to get a 4K TV working is HDMI 2.0? Guess again.
