1. A method of decoding video bitstream, wherein the bitstream comprises a picture header comprising a syntax element to be applied to all slices of a picture, the method comprising:
decoding, from the picture header, a syntax element specifying an ID of an Adaptation Parameter Set (APS) of Luma Mapping with Chroma Scaling (LMCS) prior to decoding a syntax element related to SAO from the picture header; and
decoding said bitstream using a decoded syntax element.
