Claim 17:
18. The non-transitory computer-readable storage medium of claim 17,
wherein the subset of the quantized transform coefficients comprises first quantized transform coefficients of a top row of the quantized transform block and second quantized transform coefficients of a left column of the quantized transform block, and
wherein determining the category based on the at least the subset of the quantized transform coefficients comprises:
determining the category based on a first count of non-zero quantized transform coefficients in at least a subset of the first quantized transform coefficients of the top row and a second count of non-zero quantized transform coefficients in at least a subset of the second quantized transform coefficients of the left column of the quantized transform block.
