HDR, or High Dynamic Range, is becoming one of the key elements in the adoption of 4K UHDTVs and is already emerging in the next generation of UHD content from online streaming providers and solid media providers. Thus, it’s no surprise the Technicolor has been working on a solution for single-stream HEVC HDR reference coding for testing by MPEG and other partners. It is backwards compatible with the older and still much more common standard dynamic range (SDR) which dominates most of television for now. The net result of this dual compatibility is that it will ease the burden on the video ecosystem until full adoption of next-generation TVs is completed.
