1. A method for video decoding, comprising:
determining, by a decoder, whether a disable flag is present in a picture header (PH) associated with a picture, wherein the disable flag specifies whether a coding tool is disabled for one or more slices associated with the PH; and
in response to determining that the disable flag is not present in the PH, inferring, by the decoder, a value of the disable flag according to one or more enable flags signaled in a sequence parameter set (SPS) of the picture, wherein in response to determining that the disable flag is not present in the PH, inferring the value of the disable flag according to the one or more enable flags signaled in the SPS of the picture comprises:
in response to determining that a first enable flag in the SPS equals to 1 and a second enable flag in the SPS equals to 0, inferring the value of the disable flag to be 0.
