Claim One:
1. A method for converting between standard dynamic range (SDR) media and high dynamic range (HDR) media, comprising: receiving, by a media processor, an input media item in a first format; determining, by the media processor, a luminance mapping ratio between a pixel of the input media item in the first format and a corresponding pixel of the media item in a second format; determining, by the media processor, a peak luminance scaling factor; for each pixel of the media item in the first format: for each color component value of the pixel: calculating, by the media processor, an output value based on a product of the color component value of the pixel, the luminance mapping ratio, and the peak luminance scaling factor, and replacing, by the media processor, the color component value of the pixel with the calculated output value in the second format; and providing, by the media processor, the media item in the second format.
