NTEK "Secret Sauce" as you will, If in fact they can get the streams down to 4-6 megs (Which we Know they can). Quality is very good!! So "IF" no one else (that being the competition that is) can't get 4k content down that low... & keep the quality!! remember you can advertise lower bandwidths but "does the QUALITY FOLLOW" the lowering of the Bandwidth... because that has always been the issues Bandwidth is the biggest hurdle... you can say Bandwidth is coming...right... well remember thats in on average and its a little ways out....look at this link

But remember is you get rid of SD content and only provide HD & 4K and 8K content.... and Bandwidth will always become a premium... remember the pipe will share all data..that is going on..and right now 75-80% of all data pushed has a video twist to it... then throw AI & VR and everything else besides movies!!! I'm still waiting same as everyone!!!
