摘要

A method, computer program, and computer system is provided for coding video data. Video data including one or more subpictures having one or more virtual boundaries is received. Information corresponding to the virtual boundaries is signaled in a picture parameter set, a picture header, or a slice header associated with the received video data. The video data is decoded based on the signaled information corresponding to the virtual boundaries.
