HDCP requires that each HDMI connection establish a unique link between the two devices, often called a handshake. HDCP stands for High-bandwidth Digital Content Protection. If you do want 4k content, every device in your video chain must have HDCP 2.2. This becomes important as we explore what HDCP 2.2 brings to the table.

That means if you have a device with 1.4, you’ll be limited by it until you upgrade everything in your signal chain. Unfortunately, currently HDMI 1.4 ports can’t be firmware upgraded to HDMI 2.0. Most importantly, HDMI 2.0 makes all these changes without requiring users to buy new cables. A CEC retooling could make this feature actually useful.
Our experience with HDMI CEC has been spotty at best and everything we’ve read from others agrees.
CEC promised to control all our devices with one remote through the HDMI connection. HDMI 2.0 promises a revamping of the HDMI CEC. This easily supports high-def audio in more modest multichannel system.

The quality of the audio stream has also increased up to a maximum of 1536 kHz (48 kHz sampling rate per channel for the full 32 channels). HDMI 2.0 can support up to 32 channels of audio. With Dolby Atmos and other multichannel solutions on the way from Auro and DTS, having more audio channels will become very important. HDMI 1.4 maxed out at 8 channels of audio without the use of lossy compression. Those that like racing or sport games will immediately recognize the advantage of keeping you screen private from the person you are playing against. For gaming, this allows two people to use the same screen without having to split the screen. One person would see one image while the other would see a second. While this sounds like a terrible idea, it works well when coupled with 3D glasses. HDMI 2.0 allows for two video streams to be sent to the same screen (1080p) along with audio. While 8-bit allowed for 16.7 million colors, 12-bit allows for closer to 70 billion. The increased bit-depth allows for more colors to be displayed. On top of that, the additional bandwidth allows for other advancements like: 10 and 12-bit color
While 24 frames per second is fine for watching films, video games often require higher frame rates. The increased bandwidth of Version 2.0 allows full 4k at 50 or 60 frames per second. While HDMI 1.4 allowed up to 4k resolutions (Ultra HD or 4k), it was limited to 24 frames per second. The largest change in HDMI Version 2.0 is the increase in the amount of data that can be sent. Version 1.4 also added 3D support, Audio Return Channel, and a few other features over previous versions. This allowed data transfers of up to 10.2Gbps. We’re here to demystify the new HDMI spec and help you understand just what they are getting when they purchase a new device touting HDMI 2.0 or HDCP 2.2. As seems to be par for the course with HDMI, confusion abounds mostly because of partial implementations and staggeringly low amounts of information available.
