Hardware or software products can be built to implement conversions of ATSC 3.0 services and signals to formats suitable for various redistribution systems or over-the-air broadcast translators. Such conversions might require certain methods for physical layer transmission, transport, audio, video, closed captioning, and ancillary data formats.
