In this brief, we propose an augmented data transmission (ADT)-based ultrahigh definition (UHD) television transmission system for the existing advanced television systems committee terrestrial digital television (DTV) broadcasting. The proposed system can support a rate of 12 Mb/s using a moving pictures expert group-2 (MPEG-2)-based DTV signal and a rate of 12.5 Mb/s using High Efficiency Video Coding (HEVC)-based DTV and ADT signals. By combining properly an MPEG-2-based DTV signal, an HEVC-based DTV signal and an HEVC-based ADT signal, 4K (3840 × 2160 ) UHD video can be served while providing backward-compatible high-definition video service.
