Make a Roku box that competes with NetgemHD and Netgem4k IPTV streaming/PVR/OTA viewing (DVB-T and ATSC 3 standards).
Base this on current Streambar platform, maybe with a extension box that adds local PVR storage and TV/Sat tuner (s). Multiple tuners for best multichannel recording capabilities. (Perhaps as a JV with e.g. Humax or Vestel).
Not a Roku employee
