ATSC 3.0 also called NexGen TV, is the latest US TV standard that most broadcasters plan to migrate to and holds the promise of revolutionizing OTA TV due to its technical superiority over the legacy ATSC 1.0 standard in use in the US since 2009. Due to ATSC 3.0's use of advanced HEVC encoding and the way content is processed, ATSC 3.0 can deliver legacy SD, HD content plus it can also deliver UHD, 4K or 8K content due to HEVC encoding being much more bandwidth efficient. Even if it was possible to broadcast UHD or 4K in the limited bandwidth of ATSC 1.0 it does not make sense financially to do so.
