LAS VEGAS — Sinclair Broadcast Group, along with subsidiary One Media and Technicolor, report they have successfully transmitted high-dynamic range 4KTV over the air using the proposed ATSC 3.0 standard and a prototype reception device. Sinclair made the announcement, and said it had invited a delegation of 11 South Korean broadcasters to see the demo, which also leveraged scalable HEVC encoding from French compression specialist Ateme.
