Why Is Hdcp 2.2 Important?

Hdcp 2.2: HDCP 2.2 is a technology designed to prevent illegal copying of 4K Ultra HD content. Every link in your video chain must support HDCP 2.2 — your TV, video source, and any component the video signal passes through. If just one doesn’t, you won’t see a 4K picture.

HDMI 2.0 is also required for TVs and components to be able to pass 4K video. But you can’t assume that every device that has HDMI 2.0 will also support HDCP 2.2. Every 4K Ultra HD TV we carry supports both HDMI 2.0 and HDCP 2.2.

See our growing selection of receivers that support HDCP 2.2. There are also several 4K-compatible soundbars that support HDCP 2.2. Nearly all name-brand 4K TVs have at least one HDMI input that’s compatible with HDCP 2.2.

Thought all you needed to get a 4K TV working is HDMI 2.0? Guess again. The next generation of content protection is called HDCP 2.2, and not only is it not backward compatible, but many new 4K devices also don’t even support it.

So it’s possible that the 4K TV you bought last year, or even the receiver you buy this year, might not be able to receive/pass all future 4K content.

Copy protection/content protection has been around since the VHS era, something anyone who tried to copy a Blockbuster rental can tell you. Back then it was called Macrovision, which evolved to CSS for DVD and finally HDCP, which stands for High-bandwidth Digital Content Protection, for Blu-ray players and HDTV devices like satellite and cable boxes.

HDCP 2.2 is the latest evolution of copy protection. It’s designed to create a secure connection between a source and a display. Ostensibly this is so you can’t take the output from a source (a Blu-ray player, say) and plug it into some kind of recorder, to make a copy of the content. DRM, the encryption of the content itself, is a separate issue. HDCP doesn’t care what goes across the cable, as long as that cable is secure.

It does this by creating encrypted keys between the source and the display (called the sink). Enabled repeaters, like receivers, can be in the chain as well. The source and the sink need to be in agreement, understanding their keys, or no content gets transferred. If you’ve ever hooked up the gear and gotten a blank screen (or turned on the gear in the wrong order and gotten a blank screen), this HDCP “handshake” is usually the issue.

HDCP isn’t solely over HDMI. It can be implemented to work over DVI, DisplayPort, USB, and more.

So what’s new? The encryption on the keys in version 2.2 is more advanced than previous versions which, in theory, makes the whole chain harder to break. One other interesting change with 2.2 is a “locality check.” The source sends a signal to the sink, and if the sink doesn’t get that signal within 20ms, the source kills the connection. In theory, this shouldn’t cause any issues in home setups, even over long HDMI runs (unless you have more than 3,740 miles of cable).

Is buying a 4K TV as simple as ensuring that it has a 4K resolution? Not quite, especially if you want your multi-thousand-dollar investment to last as long as possible. But as standards and technologies get sort of agreed upon and adopted by TV makers and content producers, there’s a higher degree of certainty that a 4K TV you buy today won’t become obsolete anytime soon.

However, the sad fact remains that if you’ve bought a 4K TV or receiver sometime between 2013 and early 2014, there’s a chance that it might not be able to play or pass through today’s 4K content.

Most 4K TVs support something called HDCP, which stands for High-bandwidth Digital Content Protection, but only the more recent ones come with HDCP 2.2, the latest generation content protection mechanism. Simply put, HDCP attempts to secure the connection between the source and display (and anything in between, such as receivers and game consoles), just that in 2.2 the protection system is much more advanced and stronger than before. HDCP is usually implemented on HDMI ports, but it can also be used on other types of connections, like DisplayPort and DVI.

Because HDCP 2.2 is very new and often used as a selling point, manufacturers would usually indicate which connections on their devices support it. If you don’t see the markings, check the specs sheet to verify. Shown here is the back panel of the new Yamaha RX-V779 receiver.

Now, HDCP 2.2 is really designed for 4K content, so you’re fine if you think you’re going to stick with 1080p all the way. Put another way, as long as it’s 1080p content, even if there’s a mix of HDCP 2.2 and non-2.2 devices in the chain, you’re safe.

But there will be a problem if you’re a 4K source device (e.g., a Blu-ray player) or service that’s HDCP 2.2-compliant and is trying to send protected 4K signals to a non-HDCP-2.2 4K TV. The TV would most likely show a blank screen. To make matters worse, non-HDCP-2.2 devices can’t simply be upgraded to support HDCP 2.2, because specific hardware is required.

In short, if you’re buying a new 4K TV (or home theater projector or receiver) today, it’s of your best interest to make sure that it supports HDCP 2.2. While most name-brands’ recent offerings have it, it’s still good to verify it either by checking the specs sheet or with the salesperson. Many consumers like to buy from second or third-tier brands because they’re usually more affordable; and while there’s nothing wrong with that, be mindful that such TVs often lack the latest features like HDCP 2.2.

For early adopters who’ve bought a ton-HDCP-2.2 4K TV, well, just keep all these in mind, and don’t be too surprised if some 4K content doesn’t display properly on your TV some point down the road. Once the problem crops up too frequently, you’d know that it’s time to get a new TV.

How do I avoid this?

Review the following items to make sure your Roku player is set up for HDCP 2.2.

  1. Use Premium High-Speed HDMI Cables – Be sure to use Premium High-Speed HDMI Cables for each link in the chain. Using a subpar cable for even one link may cause an HDCP 2.2 failure.
  2. Your TV must have an HDMI input that supports HDCP 2.2 – Verify that your TV has at least one HDMI input that supports HDCP 2.2. Not all 4K TVs support HDCP 2.2, including early models and some lesser-known brands.
  3. Your AVR must have an HDMI input that supports HDCP 2.2 – If you are connecting your Roku player through an AVR, the AVR must also support HDCP 2.2. In fact, every device in the chain between the Roku player and the TV must also support HDCP 2.2. Check the documentation for your AVR to make sure that HDCP 2.2 is supported on the HDMI input you are using. If you have a 4K TV or 4K HDR TV but your AVR does not support HDCP 2.2, you can still get 4K or 4K HDR video and use your AVR. You just need two connections. Connect your Roku player directly to an HDCP 2.2 input on your TV, and use either ARC (Audio Return Channel) or S/PDIF (if available) to route the audio from the TV back to the AVR.Pro Tip: If you are using an AVR and want to determine if it is the source of the issue, try removing it from the chain and connect your Roku player directly to an HDCP 2.2 input on your TV. If HDCP 2.2 support is detected in this configuration, there is an issue with the AVR connection. Try a different HDMI cable and input on the AVR if possible.

How do I determine which HDMI inputs support HDCP 2.2?

If your name-brand 4K TV, 4K HDR TV, or AVR was purchased in the past couple of years, there is a good chance it has at least one HDMI input that supports HDCP. When determining which inputs support HDCP, start with the obvious – look for the inputs labeled with “HDCP 2.2”.

Note: On some TVs, the HDMI inputs are part of an external box that is attached to the display via a special cable. This external box may be behind your TV, or it may be inside a cabinet.

  • Single input – When only a single input supports HDCP 2.2, you may see a label next to just that input as seen below:
    In these cases, assume the remaining inputs do not support HDCP 2.2. Connect your Roku player to the labeled input.
  • Note: If you are connecting more than one device that requires HDCP 2.2 and you plan to use an HDMI splitter, be sure it also supports HDCP 2.2.
  • Multiple inputs – When multiple inputs support HDCP 2.2, you may see a single label across several inputs as seen in the following example:… or you may see an individual label on each input as pictured below.Either way, assume any input that is not labeled as such does not support HDCP 2.2. Connect your Roku player to any of the labeled inputs.
  • All inputs – Unfortunately, a device that supports HDCP 2.2 on all inputs may or may not include labeling to indicate this – each brand is different. If you do not see a label but suspect your device supports HDCP 2.2, refer to the owner’s manual or online user’s guide. If you cannot find the HDCP version documented anywhere, contact the manufacturer to inquire further. Once you determine all HDMI inputs support HDCP 2.2, connect your Roku player to anyone of them.

What if my devices do not support HDCP 2.2?

You can still enjoy HD content. During setup, your Roku player will automatically select 720p or 1080p instead of 4K UHD or 4K UHD HDR. Or you can select 720p or 1080p from Settings > Display type.

4K content streams are still little more than a trickle, but that’s not stopping the industry from launching a proactive defense to protect them. The crackdown comes in the form of HDCP 2.2, an overhaul of the decade-old HDCP (High-bandwidth Digital Content Protection) specification.

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. Before you plunge into the full immersion of Ultra HD, you should know a few things about this new security feature.

HDCP was developed by Intel to secure the transmission of high-definition digital content as it travels across cables from Blu-ray players, satellite receivers, cable boxes, AV receivers, and other home-entertainment components to a display. The aim is to prevent someone from plugging a Blu-ray player into a digital recorder to make a copy of a movie.

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. 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 HDCP is most often associated with HDMI, it’s also supported through DVI, DisplayPort, and USB connections.

What does HDCP 2.2 mean?

HDCP 2.2 is a technology designed to prevent illegal copying of 4K Ultra HD content. Every link in your video chain must support HDCP 2.2 — your TV, video source, and any component the video signal passes through. HDMI 2.0 is also required for TVs and components to be able to pass 4K video.

Does HDCP 2.2 require special HDMI cable?

Every step in your AV chain (the expensive devices into which you plug the cables) generally must be HDMI 2.0a for HDR to work. As in, your TV, receiver, and source all have to be HDMI 2.0a, and usually, require HDCP 2.2 copy protection too.

What is HDMI port with HDCP support?

The term HDCP stands for High Digital Content Protection. HDCP is sometimes used on high-definition video cables such as HDMI and DVI connectors and ports. It is an encryption system created by Intel to help prevent the copying of digital video and audio content.
