Claim 6:
7. A device comprising an encoder configured to:
determine that a block of an image has been partitioned into sub-blocks;
for each sub-block, associate a subdivision level counter to the sub-block, wherein the subdivision level counter is representative of a size of the sub-block and has an increment value selected from a plurality of increment values based on the type of split of the partitioning into sub-blocks, and wherein the increment value is equal to two for all sub-blocks of a quad-split, one for all sub-blocks of binary split, two for side sub-blocks of ternary-split, and one for a center sub-block of a ternary-split;
based on the subdivision level counter, determine a quantization parameter for the sub-block; and
encode the sub-block based on the determined quantization parameter.
