Sinclair Broadcast Group is leading the market in ATSC 3.0 deployments. One of the most compelling visual aspects of this new technology is high dynamic range (HDR) video, where the images are strikingly more realistic in simultaneous contrast depth compared to today’s television viewing experience, whether it be high definition (HD) or ultra-high definition (UHD). With over-the-air (OTA) and traditional multichannel video programming distributor (MVPD) bandwidth being a valuable constrained resource, how does a broadcaster deliver this captivating new experience to many millions of viewers during the tech transition years, while many of them are still using legacy devices that cannot display the new format?

This paper describes the system architecture and technology behind an innovative method that delivers a single stream of bandwidth efficient, backward-compatible video which is decodable by both legacy and new HDR-capable devices. An HDR-capable receiver will be able to process and display the HDR video in its full glory, while a legacy (a so-called standard dynamic range or SDR) receiver will “see” the stream as an ordinary (SDR) video and display it as such. The technology behind the solution will be explained, including the processes of intelligent tone mapping and creating a backward-compatible SDR/HDR stream from a standard HDR video input.
