Claim:
1. A method of decoding video data comprising a plurality of layers, the method comprising: decoding respective syntax information for each layer of the plurality of layers of the video data, the respective syntax information for each layer of the plurality of layers defining partitioning of a picture in the layer into a number of tiles per picture for the layer, wherein the syntax information is constrained such that the number of tiles per picture for each layer of the plurality of layers is determined based on a maximum number of tiles per picture for the layer, wherein the maximum number of tiles per picture for the layer is determined based on at least one of a spatial resolution, tier information, or level information for the picture in the layer; and reconstructing the picture in the at least one layer based on the partitioning of the picture into the number of tiles per picture for the layer defined by the decoded syntax information.
