Title:
BITSTREAM RESTRICTIONS ON PICTURE PARTITIONS ACROSS LAYERS
Document Type and Number:
WIPO Patent Application WO/2015/006703
Kind Code:
A3
Abstract:
Bitstream restrictions or constraints on the partitioning of pictures across layers of video data are described. In some examples, the number of tiles per picture for each layer of a plurality of layers is constrained based on a maximum number of tiles per picture for the layer. In some examples, the number of tiles per picture for each layer of the plurality of layers is no greater than the maximum number of tiles per picture for the layer. In some examples, a sum of the numbers of tiles per picture for the plurality of layers is no greater than a sum of the maximum numbers of tiles per picture for the plurality of layers. In some examples, a second largest coding unit (LCU) or coding tree block (CTB) size for a second layer is constrained based on, e.g., to be equal to, a first LCU size for a first layer.
