Abstract
A method of coding delta quantization parameter values is described. In one example a video decoder may receive a delta quantization parameter (dQP) value for a current quantization block of video data wherein the dQP value is received whether or not there are non zero transform coefficients in the current quantization block. In another example a video decoder may receive the dQP value for the current quantization block of video data only in the case that the QP Predictor for the current quantization block has a value of zero and infer the dQP value to be zero in the case that the QP Predictor for the current quantization block has a non zero value and there are no non zero transform coefficients in the current quantization block.
