That article is incorrect... basic math proves this. The average 4k video is 100gb. Lets say you are streaming a 150 min movie. (100000mb/150min) / 60 sec is roughly around 11Mb/s to stream 4k. The x265 codec cuts this in half, 5.5Mb/s. Ntek and Netflix gives you about the same estimate. The only thing is currently the NP1 cannot support the x265... bummer
