Abstract: Control data for a motion-constrained tile set (“MCTS”) indicates that inter-picture prediction processes within a specified set of tiles are constrained to reference only regions within the same set of tiles in previous pictures in decoding (or encoding) order. For example, a video encoder encodes multiple pictures partitioned into tiles to produce encoded data. The encoder outputs the encoded data along with control data (e.g., in a supplemental enhancement information message) that indicates that inter-picture prediction dependencies across tile set boundaries are constrained for a given tile set of one or more of the tiles.

Signaling and use of MCTS control data can facilitate region-of-interest decoding and display, transcoding to limit encoded data to a selected set of tiles, loss robustness, parallelism in encoding and/or decoding, and other video processing.
