Claim:
1. A method of decoding video data and syntax information from a bitstream, wherein the video data comprises a picture, the method comprising: determining a partitioning, indicated by the syntax information, of the picture into a plurality of largest coding units (LCUs); determining a partitioning of the picture into a plurality of rectangular tiles by one or more tile boundaries indicated by the syntax information, wherein each of the tile boundaries is a horizontal or vertical line across the picture, and wherein each of the plurality of LCUs is within one of the plurality of rectangular tiles and each of the rectangular tiles comprises a respective subset of the plurality of the LCUs; determining a partitioning, indicated by the syntax information, of the picture into a plurality of slices by one or more slice boundaries, wherein the slice boundaries are not constrained to be the same as the tile boundaries, and wherein each of the plurality of LCUs is within one of the plurality of slices and each of the slices comprises a respective subset of the plurality of the LCUs; decoding, from the bitstream, syntax information that indicates one of a plurality of tile groups to which each of the plurality of tiles is assigned, wherein the video data comprises first video data of a first tile group of the plurality of tile groups and second video data of a second tile group of the plurality of tile groups, and wherein the first video data and the second video data are separately included in at least one of: a first one or more NAL units and a second one or more NAL units, a first one or more of the plurality of slices and a second one or more of the plurality of slices, or a first one or more packets and a second one or more packets; and reconstructing the picture, using at least one of the first video data or the second video data, based on the determined partitioning of the picture into the plurality of LCUs, the determined partitioning of the picture into the plurality of tiles, the determined partitioning of the picture into the plurality of slices, and the information that indicates the one of the plurality of tile groups to which each of the plurality of tiles is assigned.
