    4K and 8K should make Hollywood happy. Take a long time to torrent a movie at 8K.

    Not at school! We get 90 Mbps down and up in the library lol (Not that I'd pirate a movie, and certainly not using the school's internet)

    There was a mention of using two 6 MHz channels for 4K and perhaps 8K with new compression algos and perhaps new modulation instead of 8VSB.

    Switching to MPEG-4 would help as well.

    Only today only for tests 4K transmitting as no new H.2XX standard developed not telling about equipment...

    One 6 MHz channel with 8VSB modulation giving max rate 19.2 Mbps is not enough for 4x pixel's count with current H.264 or VC-1 compression.
    Perhaps static picture or FR = 7.5 fps. :)
