Abstract:
A device for decoding video data receives the video data, determines a scaling parameter for a block of the video data; and scales the block in a video decoding loop using the scaling parameter to increase a dynamic range for luminance values of the block. A device for encoding video data partitions the video data into blocks; determines a scaling parameter for a block of the video data; and scales the block in a video encoding loop using the scaling parameter to decrease a dynamic range for luminance values of the block.
