1. A method of encoding video data, the method comprising:
signaling a first syntax element specifying whether each subpicture consists of one and only one rectangular slice, or each subpicture may consist of one or more rectangular slices;
signaling a second syntax element, wherein the second syntax element plus 1 specifies a number of rectangular slices in each picture referring to a picture parameter set in a case that the first syntax element specifies that each subpicture may consist of one or more rectangular slices;
determining whether or not a third syntax element is to be signaled based on the second syntax element;
signaling the third syntax element, specifying whether or not fourth syntax elements are present in the picture parameter set, based on the second syntax element; and
signaling the fourth syntax elements, wherein one of the fourth syntax elements specifies a difference in a tile index between two rectangular slices, based on the second syntax element and the third syntax element.
