Abstract: An apparatus configured to code (e.g., encode or decode) video information includes a memory unit and a processor in communication with the memory unit. The memory unit is configured to store video information associated with a base layer and an enhancement layer. The processor is configured to up-sample a base layer reference block by using an up-sampling filter when the base and enhancement layers have different resolutions; perform motion compensation interpolation by filtering the up-sampled base layer reference block; determine base layer residual information based on the filtered up-sampled base layer reference block; determine weighted base layer residual information by applying a weighting factor to the base layer residual information; and determine an enhancement layer block based on the weighted base layer residual information. The processor may encode or decode the video information.

Abstract: An example method includes determining whether an encoded block of residual video data was encoded losslessly in accordance with a lossless coding mode, based on whether transform operations were skipped during encoding of the block of residual video data, and if the block of residual video data was encoded losslessly, then decoding the encoded block of residual video data according to the lossless coding mode to form a reconstructed block of residual video data, where decoding the encoded block of residual data comprises bypassing quantization and sign hiding while decoding the encoded block of residual video data, and bypassing all loop filters with respect to the reconstructed block of residual video data.

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.
