HDCP 2.2 on receivers and TVs: what is it and how does it work?
Recently, we have seen more and more home cinema products, including receivers and TVs, that have HDCP 2.2. But what exactly is it?

Recently, we have seen more and more home cinema products, including receivers and TVs, that have HDCP 2.2. This specification becomes even more important with the advent of 4K Ultra HD content, but what exactly is it?

What is HDCP?

DHCP (High-bandwidth Digital Content Protection) is a standard developed by Intel. The standard makes protection of digital content that is sent via a digital connection (for example HDMI or DVI) possible. Using this security standard, content providers and manufacturers of AV equipment encrypt data transmission and it is only possible to display the content with equipment that is authorized to do so. Each device that supports HDCP therefore has a unique number and when this number is related to the display of illegal content, it will be blacklisted and you as a user may have a problem. This is because the equipment can no longer display protected content.

HDCP 2.2

Several new receivers  and televisions use the new HDCP 2.2 standard. This standard must make it impossible to unlawfully play protected content and will mainly be used by creators and distributors of 4K Ultra HD content. For example, 4K movies, streaming videos and broadcasts are provided with HDCP 2.2 protection. Only equipment that supports this standard can play the protected content. If this is not the case, the content, for example a 4K movie, will not be shown or shown in a lower resolution. It is therefore also important that you check whether all your equipment (possibly with a firmware update ) supports the standard.
