Conversion of Conventional Video Display for High Dynamic Range Televisions
This paper presents the results of subjective experiments undertaken by the BBC R&D to create a reversible solution for the display of conventional video content on a Hybrid Log-Gamma high dynamic range (HDR) television. This algorithm is simple to implement in both hardware and software and is designed to allow both the use of archive footage and conventional cameras in an HDR television service and the generation of a non-HDR service in such a way that the transmission-chain of the non-HDR service can reverse the algorithm. This ensures no quality reduction for the non-HDR viewer.
