Streaming online 4K video or back to a Flash video player

Just yesterday, Gerd Hilgemann published the result of his work on streaming 4K video. As stated in his original note (this is a topic translation, a link to a demo inside):

He completed work on a live demo of streaming video in 4K format (3840x2160), which was made possible by Flash technology, or rather multithreading, Stage3D and StageVideo. Repeat this on HTML5 failed.
I used HTTP Live Streaming (also known as HLS) as a container for streaming and mpegTS for video decoding, which was also implemented in Flash.

You do not need a special server for broadcasting, and the processor load is 40% lower than on YouTube!

For backward compatibility on mobile devices, video is transmitted in 720p format and consumes only 1.5Mbit / s. Believe it or not, 4K video uses only 3.5Mbps .

So far, we have been able to test on ATI and Nvidia video cards, as well as not waiting until Red 4K Player comes to my hands (I understand this is about it - note of the translator) and its SDK :)

From myself I want to add that I am still not used to watching 1080p online, so the 4K perspective pleases me and scares at the same time. Although probably my fear of this is not comparable with the expectations on this score from such streaming video giants as YouTube, Vimeo , and RedTube .
