Abstract
Methods and devices are provided for reducing the decoding latency introduced by LMCS. In one method, during encoding of a coding unit (CU), a plurality of reconstructed luma samples is selected from a first pre-determined region neighboring to a second pre-determined region where the CU is located, an average of the plurality of reconstructed luma samples is calculated, and the average of the plurality of reconstructed luma samples is used directly, without any clipping, in deriving a chroma residual scaling factor, a bitstream comprising luma mapping with chroma scaling (LMCS) related information is formed.
