US Patent 10897612 Coding identifiers for motion constrained tile sets

An example device for processing video data includes a memory configured to store video data; and one or more processors implemented in circuitry and configured to determine a value of a syntax element of a temporal motion constrained tile sets (MCTS) supplemental enhancement information (SEI) message of an access unit, wherein the value of the syntax element represents whether all tiles of one or more corresponding pictures are included in separate MCTSs; and when the value of the syntax element indicates that the tiles of the corresponding pictures are not included in the separate MCTSs, set an MCTS identifier of the MCTS of a current picture of the access unit equal to a value of an index of the MCTS, the current picture being one of the corresponding pictures.
