BITSTREAM RESTRICTIONS ON PICTURE PARTITIONS ACROSS LAYERS

摘要

Bitstream restrictions or constraints on the partitioning of pictures across layers of video data are described in which, the largest coding unit (LCU) or coding tree block (CTB) size for a second layer is constrained based on, e.g., to be equal to, the LCU size for a first layer. For example, the CTB size of an enhancement layer may be set equal to the CTB size of ist active reference layers when performing SNR-scalable coding.
