JVET-L0686 Spec text for the agreed starting point on slicing and tiling [Y.-K. Wang, Hendry (Huawei), R. Sjöberg (Ericsson), S. Deshpande (Sharp)] [late]
This was discussed Thursday 11 October 1300 (GJS).
Draft text was provided. Basically, everything that had been at the slice header level was put at the tile group header level (e.g., I versus B versus P slice type).
It was discussed whether to put the entry point offsets earlier in the header to avoid excessive parsing to get to the information, e.g., immediately after the num_tiles_in_tile_group_minus1 syntax element, but this was deferred for further consideration. It was agreed to condition the presence of num_tiles_in_tile_group_minus1 on whether there is more than one tile in the picture. There was a bug in the tile group data syntax, since it would need both a loop for the number of tiles and, for each tile, the number of CTUs in the tile. Decision: Adopted (as modified).
