Technicolor and Sinclair Broadcast Group have demontrated an UltraHD (UHD) with High Dynamic Range (HDR) live broadcast based on proposed ATSC 3.0 technologies. The demonstration marks a step forward in the distribution of live UHD and HDR content for future broadcasting systems.

The series of broadcasts, integrated into Sinclair's experimental OFDM transmission system and transmitted under real-world conditions outside of a laboratory, delivered high quality HDR content broadcast at HD and 4K/UHD resolutions in a single-layer with backwards compatible standard dynamic range. Both HDR and legacy devices, including fixed position TVs and mobile devices, were all able to receive and display the broadcast signal. Based on open standards from MPEG (HEVC, SHVC, 3D Audio from MPEG-H) plus HDR, with MMT and DASH transport streaming standards, and Technicolor’s Staggercast and Fast Channel Change technologies, the broadcast met the most ATSC 3.0 requirements of any previously demonstrated system. Mobile tests yielded a received signal at up to 60 miles away and, separately, the receipt of the mobile broadcast signal at up to 120 miles/hour.

This latest demonstration follows Technicolor and Sinclair’s deployment of Technicolor's ATSC 3.0 4K UltraHD test bed platform and receipt of an over-the-air signal.
