Backward compatible UHDTV transmission based on ADT system for the ATSC terrestrial DTV broadcasting

This paper proposes a backward compatible UHDTV transmission based on augmented data transmission (ADT) system for the ATSC terrestrial DTV broadcasting. The proposed system provides MPEG-2 DTV signal with a rate of 19.3 Mbps and HEVC-base ADT signal with a rate of about 7 Mbps. If we combine MPEG-2 DTV signal and HEVC-base ADT signal properly, we can provide 4K UHD video service as well as backward compatible HD video service simultaneously.
