YUV signal generation for high dynamic range video content
An encoder may include a luma transform, a transformer, and a chroma transform. The luma transform may determine a linear luminance value based upon a plurality of primary color values of a pixel. The transformer may generate a transformed luminance value based upon the linear luminance value and a plurality of transformed color values based upon corresponding more than one of the primary color values of the pixel. The chroma transform may determine a plurality of chroma values based upon corresponding plurality of transformed color values and the transformed luminance value of the pixel.
