1. A method of decoding implemented by a video decoder, comprising:
receiving a video bitstream including a picture unit (PU), wherein a syntax element in a picture header (PH) of the PU has a first value to specify that a current picture is a gradual decoding refresh (GDR) picture, and wherein the PH includes a picture order count (POC) least significant bit (LSB) that specifies a POC modulo MaxPicOrderCntLsb for a picture associated with the PH; and
decoding the GDR picture from the PU to obtain a decoded picture.
