set. The apparatus may select and indicate IPPE tile sets to comprise related tile sets, such as tile sets of collocated patches of different types. In-picture prediction may be enabled among tiles of an IPPE tile set. For example, intra block copy prediction may be enabled from the first-layer texture tile to the collocated second-layer texture tile, or motion vector prediction as described in other embodiments may be enabled from a tile of a first type (e.g., texture) to a collocated tile of a second type (e.g., depth). [00187] Referring now to Figure 5A, an example NxM tile grid 50 is used (N = M = 5) for coding a plenoptic image/video, one sub-aperture image per tile. In-picture prediction may be used within the tiles of a picture. IPPE tile sets 52 and 54 may be indicated in or along the bitstream associated with the tile grid. Motion-constrained tile sets (MCTS), e.g., one MCTS per tile, may be encoded and indicated in or along the bitstream. Each tile in the tile grid 50 has a tile identifier assigned to it. The tile identifiers indicate the raster scan order of tiles within the tile grid. The following tile id assignment may be indicated in or along the bitstream: 24, 20, 9, 13, 21, 19, 8, 1, 5, 14, 12, 4, 0, 2, 10, 18. 7. 3. 6, 15, 23, 17, 11, 16, 22 [00188] An IPPE tile set, such as IPPE tile set 52, may be extracted. Figure 5B illustrates an extracted IPPE set 52. [00189] For the extracted bitstream, the following tile id assignment may be indicated in or along the bitstream (indicating the tile id order in raster scan order of tiles within the tile grid): 0, 2, 10, 3. 6, 15, 11, 16, 22 [00190] As explained earlier, the assignment of tile identifier values to tile positions may be indicated for example in a picture parameter set. As mentioned earlier sample entries of ISOBMFF tracks may contain parameter sets. Thus, an extracted bitstream may be constructed by extracting the VCL NAL units of the desired slices and/or tiles and by modifying assignment of tile identifier values in parameter set(s). The modified parameter sets may be provided in a sample entry for a track whose samples contain the extracted VCL NAL units.
