3. An apparatus of video processing method in a video encoding or decoding system, the apparatus comprising:
one or more electronic circuits configured for:
receiving input video data associated with a current picture;
when inter-layer coding is enabled for the current picture, signaling or parsing a first syntax element, wherein the first syntax element indicates whether to infer or predict subpicture information of a current layer of the current picture from a target layer;
when the first syntax element indicates that information of the current layer of the current picture is predicted or inferred from the target layer, signaling or parsing a second syntax element to determine information about the target layer for obtaining the subpicture information of the current layer of the current picture; and
encoding or decoding the current layer of the current picture using the subpicture information of the current layer of the current picture.
