When we stream 4k video from Netflix for example, they recommend a minimum speed of 25 mbps.But HDMI 2.0 has a bandwidth of 18.0 Gbit/s
How can we recieve 4k video with a connection speed of only 25 mbps when we need 18.0 Gbit/s to send the video to our TV?
I think it is to do with compressed vs raw 4k but do we really compress it to this an extreme? I would have thought this would result in so much loss that we are no where near 4k in the end.

* Compression.
* You are downloading a map and a set of instructions that tell your device how to recreate each frame of the video.
* Once that frame is recreated, the data for over 8 millions pixels needs to get from your device to the display.
* Also up to 8 channels of audio, plus other data, and the HDMI spec also includes room for a 100mbps ethernet link embedded inside the HDMI link
