Abstract

A video coding mechanism is disclosed. The mechanism includes partitioning (1001) a picture into a plurality of first level tiles. A subset of the first level tiles is partitioned (1001) into a plurality of second level tiles. The first level tiles and the second level tiles are assigned (1003) into one or more tile groups such that all second level tiles created from a single first level tile are assigned to a same tile group. The first level tiles and the second level tiles are encoded into a bitstream. The bitstream is stored for communication toward a decoder. Figure 8C
