Sinclair Demos HDR 4KTV Over ATSC 3.0 in Vegas reports that 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.

The broadcast was done at Sinclair-owned Vegas NBC affiliate, KSNV. The signal originated on KSVN’s facility on Black Mountain near Henderson, Nev., using a prototype Teamcast modulator and was received at KSNV facilitities 15 miles away by prototype receiver technology developed by Sinclair subsidiary ONE Media, and Technicolor, according to Sinclair. The payload included HDR UHDTV scalable HEVC—both base and enhanced layer—with 3D audio and other overhead in half of the 6 MHz channel. Scalable HEVC or SHVC, is the scalabilty extension of HEVC, and “provides support for spatial, SNR and color gamut scalability,” according to Fraunhofer. SHVC was leveraged in this case to accommodate high dynamic range, or HDR. The bitstreams were encoded using the only single pass live SHVC encoder available, according to a source at site.
