Significance map encoding and decoding using partition selection

摘要

SIGNIFICANCE MAP ENCODING AND DECODING USING PARTITION 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 (PI, P2.. .P6), wherein the bit positions (PI, P2.. .P6) within each part are associated with a given context (CO, C1.. .Cs). Example partition sets and processes for selecting from amongst predetermined partition sets and communicating the selection to the decoder are described. 1221 22 24 26 14 P edtor asoQuantizer Enrp 28 Dequantizer inverse Transform 20 Processor Coding Mode 32 Selector 36 34 Deblocking Processor Frame Store
