HDCP 2.2 content protection for 4K video will frustrate consumers
While HDCP 2.2 was developed to defeat media pirates, it has far more potential to thwart ordinary folks who just want to enjoy a movie in the privacy of their home. With current versions of HDCP rendered ineffective and all manner of 4K content on the horizon, Hollywood decided it needed stronger security. Cryptanalysts demonstrated HDCP to be breakable three years before the FCC approved it as a "Digital Output Protection Technology" in 2004. By 2010, a master key that effectively neutralized HDCP v1 was leaked. Versions 2.0 and 2.1 were summarily cracked as well. The main difference with 2.2 is the encryption systems used in the handshake are more complex than in prior versions. HDCP 2.2 is not backward compatible with the previous versions of HDCP that are currently used by most of the HD devices in all our homes. Having a non-HDCP 2.2 sound bar or AV receiver in your home theater system will be enough to terminate the handshake.
If you jumped on the Ultra HD bandwagon when 4K TVs and media devices first hit stores in 2013, don’t assume your purchases support HDCP 2.2 and will work with future 4K devices and content—most of those early models don’t and won’t. If you’ve haven’t dipped a toe into the 4K pool yet, we stand by our advice to wait it out until content producers and providers crank out enough 4K content to make the necessary hardware-upgrade expense worth it. That may take years.
