SDR to HDR conversion

A proposed solution for transforming standard dynamic range to high dynamic range is on show in the Future Zone. Uniquely it is claimed to be able to do this in real time while preserving the artistic intent.

The prototype (GPU-based) version, from French lab b-com, targets broadcast applications including mixing SDR and HDR live sources and the conversion of legacy content to HDR. It is also intended for live playout of SDR interstitials in an HDR programme.

The technology is based on an algorithm which makes smart use of the target display’s high dynamic range while preserving the original style of the source SDR video.
