If you are buying a new UHD TV, a media player, or an AVR for a home theater treat, make sure you have learned something about the concept of HDCP. This could save you from the awkward situation where you have squandered a lot of money only to see a blank screen or the error “HDCP unauthorized. Content disabled.” on it. To have your video content played smoothly, the key is to assure that what you are buying is all HDCP-compliant.
What is HDCP and why it is important
A newbie to AV setup may ask – what is HDCP? Well, HDCP stands for High-bandwidth Digital Content Protection. This protocol is formed to protect digital audio and video content from being copied and distributed as the signals travel through connections (mainly HDMI, DP, and DVI) to devices. Hence, if the content you are playing is HDCP-encrypted and the receiver like an AVR or an HDTV does not support HDCP, the a/v signals could be rejected and fail to show themselves on your screen.
You may have heard about HDCP and wondered what is the difference between HDCP 1.4 and HDCP 2.2. We will talk about it later.
In fact, if you are planning a home theater setup, not only your audio-video receiver and HDTV shall support HDCP, but also the HDMI extender (if you are using an HDMI extender to extend your HDMI cables), HDMI splitter/switch, and the cables you are using for the wiring should be HDCP-compliant. As long as you are watching the programs that are protected by such code (which people with a home theater almost 99% do), being HDCP-compliant is a must for your complete AV experience.
Content and services that use HDCP
HDCP is required to stream Netflix from a device connected to your TV. It is the same for Roku, programs on Apple TV, NowTV, and most streaming services that offer 4K movies and copyright content.
In order to help viewers out of the HDCP error, Netflix published a post introducing ways to troubleshoot. Well, sometimes people get frustrated and have to purchase a new TV or AV device to replace the old one if they have never noticed this trick for home theater setup in the first place.
HDCP 1.4 vs HDCP 2.2: what’s the difference?
HDCP 1.4 and HDCP 2.2 are the most widely used standards now. Sometimes people may confuse them with HDMI (see HDMI 2.0 VS HDMI 2.1). In fact, they are totally different stories. HDCP 1.4 and HDCP 2.2 are two generations of content protection management.
In most cases, HDCP 1.4 is adopted to protect full HD content and HDCP 2.2 is an upgraded version to protect 4K UHD. If you wanna enjoy 4K content that is managed by HDCP 2.2, an HDCP 1.4 device may fail your attempt.
HDCP is downwards compatible. That is, HDCP 2.2 devices would be happy to give way to HDCP 1.4 content. In the future, the next generation of HDCP 2.3 may become more popular for 8K content
