The most absurd thing about the HDCP protection scheme is that there is no HDCP-compliant way to circumvent it for legitimate use cases. Unfortunately, the only official way to comply with HDCP is to buy an HDCP-compliant device. If any device in the chain is not HDCP compliant, the video stream will fail.Ībsolutely no one should have to buy a new television set, upgrade their perfectly fine audio-video receiver, or otherwise spend significant piles of money to solve a problem that shouldn't exist in the first place. Unfortunately, however, there are a host of situations where HDCP gets in the way of consumers doing perfectly legal things with their devices and content. You power on your Blu-ray player or DVR, it makes nice with your HDTV, and you live a happy life never knowing what HDCP even is. ![]() The outputting device says "Hey display! Are you HDCP compliant? Here is my license, show me your license!" The display (or other HDCP compliant device) returns with "Why yes, I am legit! Here is my license!" When that process works, it happens within a thousandth of a second and you, the consumer, never even notice. ![]() Each HDCP-compliant device, like your Blu-ray player or Xbox, has a license and the ability to talk to the receiving device on the other end of the HDMI cable. ![]() There is a licensing body that issues licenses for HDCP devices. Although HDCP's underlying encryption and protocols are sophisticated and outside the scope of this article, the basic premise of how it works is quite simple.
