Abstract

A decoder can be configured to decode a picture from a bitstream in which the picture is partitioned into a plurality of tile groups. The decoder can decode a first part of the bitstream (including parameter set data) to form a size mapping that maps a tile group index value to a number of tiles to be decoded for a first tile group. The decoder can further decode a second part of the bitstream (including includes coded tile groups) by: decoding, from a tile group header in a first coded tile group, a first tile group index value for the first tile group; determining a first size for the first tile group based on the first tile group index value and the size mapping; and decoding a number of coded tiles to form the decoded picture, the number of coded tiles being equal to the first size.
