Patent ID: 10284863

Abstract:
A device may determine, based on data in a bitstream, a luma sample (Y) of a pixel, a Cb sample of the pixel, and the Cr sample of the pixel. Furthermore, the device may obtain, from the bitstream, a first scaling factor and a second scaling factor. Additionally, the device may determine, based on the first scaling factor, the Cb sample for the pixel, and Y, a converted B sample (B′) for the pixel. The device may determine, based on the second scaling factor, the Cr sample for the pixel, and Y, a converted R sample (R′) for the pixel. The device may apply an electro-optical transfer function (EOTF) to convert Y′, R′, and B′ to a luminance sample for the pixel, a R sample for the pixel, and a B sample for the pixel, respectively.
