Abstract:
Methods of encoding and decoding for video data are described in which multi-level significance maps are used in the encoding and decoding processes. The significant-coefficient flags that form the significance map are grouped into contiguous groups, and a significant-coefficient-group flag signifies for each group whether that group contains no non-zero significant-coefficient flags. If there are no non-zero significant-coefficient flags in the group, then the significant-coefficient-group flag is set to zero. The set of significant-coefficient-group flags is encoded in the bitstream. Any significant-coefficient flags that fall within a group that has a significant-coefficient-group flag that is non-zero are encoded in the bitstream, whereas significant-coefficient flags that fall within a group that has a significant-coefficient-group flag that is zero are not encoded in the bitstream.

Claim (Index 16):
The non-transitory processor-readable medium claimed in  claim 15 , wherein the instructions, when executed, further cause the one or more processors to, prior to determining that said one of the coefficient groups is to be modified to contain all zero significant-coefficient flags,\n apply a rate distortion optimization to the transform unit; and adjust a level of one or more transform coefficients based on the rate distortion optimization to produce a rate-distortion optimized transform unit, wherein the significant-coefficients of the significance map represent the locations of non-zero coefficients in the rate-distortion optimized transform unit.
