Claim Text:
1. A method of decoding video data, the method comprising: receiving a lossless coding syntax element for a current block of video data, the lossless coding syntax element indicating that the current block of video data is encoded using a lossless coding mode, the lossless coding syntax element being separate from a quantization parameter (QP) value; determining that the current block of video data is a current quantization block based on a size of the current block of video data; assigning a delta quantization parameter (dQP) value of zero for the current quantization block, wherein the dQP value is a difference between the QP value and a value of a QP Predictor; determining the QP value for the current quantization block based on the assigned dQP value and the QP Predictor; and decoding the current quantization block according to the lossless coding mode and the determined QP value.
