Abstract:
A method of processing video data including receiving video data, determining luma scale parameters for each of a plurality of ranges of codeword values for luminance components of the video data, performing a dynamic range adjustment process on the luminance components using the luma scale parameters, determining chroma scale parameters for chrominance components of the video data using a function of the luma scale parameters, and performing a dynamic range adjustment process on the chrominance components of the video data using the chroma scale parameters.
