Otherwise:
- HDCP master keys leaked or were computed (no one knows for sure) (for older HDCP versions ~2010)
- HDCP 2.0/2.1 had a flaw where it was possible to observe a key exchange repeat it and extract the Km key, thereby cracking the encryption
- HDCP 2.2 is still unbroken from a key extraction standpoint, however there are devices available which talk HDCP 2.2 to the sender and send the same stream with HDCP 2.1 on another port (where you can use existing attacks).. Such devices are "allowed" a lawsuit against the manufacturer of such a device was dropped.
In the end it will always be possible to extract the videostream, as decryption happens in a chip in the monitor. You just have to capture the output of that chip.
This is what some HDMI-Scalers/Splitters basically do.. They have a chip like in a monitor which decrypts the stream and they output it unencrypted on a output HDMI port.
What is done against this: The keys of such devices are blacklisted, however this is a cat and mouse game, as you just have to use a chip from another devicetype with a different key.
So yeah 4k UHD HDR 12bit ripping with Dolby Atmos no Problem in Reality.. That´s why you can download UHD VOD Rips
