Abstract
Some embodiments provide a method of decoding a current video block in a video picture. From several partitioning schemes, the method identifies a partitioning scheme that is used to partition the current video block. Based on the identified partitioning scheme, the method selects one derivation to compute a first quantization parameter for the current video block from several candidate derivations for computing the first quantization parameter. The method computes a second quantization parameter for the current video block based at least in part on the computed first quantization parameter. The method then uses the computed second quantization parameter to decode the current video block.
