[0016] In some implementations of such an apparatus, the computer program code is further configured to, with the at least one processor, cause the apparatus to encode the indication of the in-picture-prediction-enabled tile set in one or more of: a sequence parameter set associated with the bitstream, a picture parameter set associated with the bitstream, or a supplemental enhancement information message associated with the bitstream. In some embodiments, the indication indicates whether the in-picture-prediction-enabled tile set is a temporal motion-constrained tile set. In some embodiments, the indication comprises a dependency forest or graph that indicates a set of prediction dependencies for one or more tiles that are not other non-in-picture predicted tiles to one or more tiles of the in-picture- prediction-enabled tile set. In some embodiments, the indication comprises a set of anchor positions for a set of intra block copy motion vectors of a set of dependent tiles in the in- picture-prediction-enabled tile set. [0017] In another example embodiment, an apparatus is provided that includes means for receiving or encoding a bitstream comprising a coded picture, the coded picture comprising one or more tiles. The apparatus further includes means for identifying one or more dependent tiles from the one or more tiles. The one or more dependent tiles are dependent on another dependent tile within a coded picture or form a logical atomic unit with another dependent tile. The apparatus further includes means for constructing an indication of an in-picture- prediction-enabled tile set comprising the one or more dependent tiles. The apparatus further includes means for causing storage of the bitstream and the indication of the in-picture- prediction-enabled tile set. [0018] In some implementations of such an apparatus, the apparatus further includes means for encoding the indication of the in-picture-prediction-enabled tile set in one or more of: a sequence parameter set associated with the bitstream, a picture parameter set associated with the bitstream, or a supplemental enhancement information message associated with the bitstream.

In some embodiments, the indication comprises a set of anchor positions for a set of intra block copy motion vectors of a set of dependent tiles in the in-picture-prediction-enabled tile set. [0019] In yet another example embodiment, a computer program product is provided that includes at least one non-transitory computer-readable storage medium having computer executable program code instructions stored therein with the computer executable program
