Abstract – Although UHD and HDR are usually mentioned together, High Dynamic Range (HDR) is not limited to just Ultra HD. High Definition (HDTV) can also benefit from a dramatic improvement in life-like picture quality with HDR. That’s because most people sit too far away from their TVs and are unable to see the full resolution of UHD/4K. A properly set up 1080p image with HDR will look better than a UHD image with Standard Dynamic Range (SDR) at typical viewing distances. HD-HDR can be produced and delivered for post-produced and live events. It can be compatible with both legacy SDR and 4K TV sets. In addition to recovering images from dark shadows or bright areas, HDR offers a far better and more realistic picture, similar to what the eye sees in real-life. The HD-HDR signal will pass through most bandwidth and data rate issues that have slowed the adoption of UHD/4K. HD-HDR can be delivered by cable, satellite, OTT and ATSC 3.0.
