Abstract (en)
[origin: WO2020263132A1] A method for still picture and/or video coding comprising, determining if lossless coding is applied on a current coding block; wherein in response to the determined result that lossless coding is applied on the current coding block, inferring a dependent syntax element to be zero, when said dependent syntax element is not present in a bitstream; and coding the current coding block by lossless coding based on the dependent syntax element.
