NextGen TV

ATSC 3.0 aka NextGen TV over-the-air (OTA) standard for North America. ATSC 3.0 is a new version of the Advanced Television Systems Committee standards, defining how exactly television signals are broadcast and interpreted. ATSC 1.0 standard definition goes up to 1080i (interlaced) MPEG-2 while the upgraded ATSC 3.0 offers the higher than human perception on a home TV screen 4K Ultra High Definition compression via the H.265 HEVC codec.

ATSC 3.0 will also let broadcasters track your viewing habits with the Internet integration component. Tracking information can be used for targeted advertising, just like companies such as Facebook and Google use online.

NextGen TV is IP-based, so in practice it can be moved around your home just like any internet content can right now. For example, you connect an antenna to a tuner box inside your home, but that box is not connected to your TV at all. Instead, it's connected to your router. This means anything with access to your network can have access to over-the-air TV.

Conversion of TV broadcast stations in the United States is not being mandated by the FCC as of 2023. The transition to DTV was federally mandated, but the FCC’s approach to ATSC 3.0 is to put the decisions and timeline mostly in the hands of station owners, with some guidance from the commission on protecting traditional digital broadcasts.
