In what language does that word work like that?
Fine. Virtually EVERY high-definition source DOES look better and sharper in 1080p streamed at 8mps than they will in 4K streamed at 4mbps.
Before you split hairs at the word "virtually" in my statement, I'm only excluding those video sources that are typically used for streaming demos. Those would be sequences that had large amounts of static or blurred background. The butterfly source that NTEK used at CES 2014 had an out-of-focus background. Such backgrounds are very easy to encode. Another example would be those large city or landscape overview shots that are used a lot to show 4K, where the buildings or mountains don't move, but the cars or clouds do. Anything static makes the encoding too simple.
Best would be to test a variety of real-world inputs and also inputs designed to push the encoder to its limits. Test patterns panning at odd angles, or even newscasters moving a bit while wearing fine striped jackets will really show you whether you're picking up the higher frequencies.
The fact that NTEK never sent NP-1 or Ultraflix to testers early last year tells me that their video quality is not good enough to charge a premium price for, and in fact isn't any better than 1080p Blu-Ray at under 15mbps, just like Netflix found out with the same codec.
The other relevant fact is that NTEK doesn't even claim to have invented any new compression technique. Believe me, if their streams at 6mbps were superior, objectively or subjectively, to Netflix 4K at 15mbps, then they'd patent the bejeezus out of the technique and license it for many times the company's current market cap.
Think what the inventors of MP3 (that'd be the German firm Frauenhofer) have made.
Since NTEK has never patented a thing, nor made any feints at all in the direction of doing so, proves beyond a shadow of a doubt that they have nothing special at all. Their vague promise that they do was never anything but a huge lie. Mind you, it's a very common lie in the video compression business, so the studios wouldn't have been taken in for a second.
