Abstract
Methods and apparatuses for video coding are provided. The method includes that a decoder receives a first syntax element in picture parameter sets (PPS) specifying whether a picture corresponding to the PPS comprises one or more network abstraction layer (NAL) units and whether the one or more NAL units have a same NAL unit type, receives a second syntax element in a picture header (PH) specifying whether the picture corresponding to the PH is an intra random access point (IRAP) picture or a gradual intra refreshing (GDR) picture, and determines a value of the first syntax element based on a value of the second syntax element or determines the value of the second syntax element based on the value of the first syntax element.
