1. A method performed by at least one processor, the method comprising:
obtaining a coded video stream by coding video data, the coded video stream including a picture partitioned into a plurality of sub-pictures, and further including adaptive resolution change (ARC) information that is signaled directly within a header of a sub-picture from among the plurality of sub-pictures, or that is provided within a parameter set and directly referenced in the header; and
outputting the coded video stream,
wherein the header is within a network abstraction layer (NAL) unit that has a scope of the sub-picture.
