Methods of encoding and decoding for video data are describe in which significance maps are encoded and decoded using non-spatially-uniform partitioning of the map into parts, wherein the bit positions within each part are associated with a given context. Example partition sets and processes for selecting from amongst predetermined partition sets and communicating the selection to the decoder are described. 描述了针对视频数据的编码和解码方法，在所述方法中使用图到部分的非空间均匀分区来编码和解码重要性图，其中每个部分内的比特位置与给定的上下文相关联。描述了示例分区集合和从中选择预定分区集合以及将所述选择传达给解码器的过程。
