(Unless you’re running miles of cable through your living room, that’s not likely to be an issue.) The compatibility conundrum HDCP 2.2 also includes a “locality check:” If the source signal is not received by the sink within 20ms, the source kills the connection. The main difference with 2.2 is the encryption systems used in the handshake are more complex than in prior versions. With current versions of HDCP rendered ineffective and all manner of 4K content on the horizon, Hollywood decided it needed stronger security. That brings us to the new-and-improved HDCP 2.2.

Versions 2.0 and 2.1 were summarily cracked as well. By 2010, a master key that effectively neutralized HDCP v1 was leaked. Cryptanalysts demonstrated HDCP to be breakable three years before the FCC approved it as a "Digital Output Protection Technology" in 2004. Unfortunately for Hollywood, the technology never really lived up to its promise. HDMI is the most common cable used to connect high-definition TVs. While HDCP is most often associated with HDMI, it’s also supported through DVI, DisplayPort, and USB connections. The source exchanges encryption keys with the sink in a handshake, and if the keys aren’t in agreement, you don’t get a picture. While DRM (digital rights management) encrypts the content itself, HCDP secures the cable between the source and the “sink”-the TV, monitor, or the video projector that display the content.
