Abstract: A video coder determines a candidate for inclusion in a candidate list for a current prediction unit (PU). The candidate is based on motion parameters of a plurality of sub-PUs of the current PU. If a reference block corresponding to a sub-PU is not coded using motion compensated prediction, the video coder sets the motion parameters of the sub-PU to default motion parameters. For each respective sub-PU from the plurality of sub-PUs, if a reference block for the respective sub-PU is not coded using motion compensated prediction, the motion parameters of the respective sub-PU are not set in response to a subsequent determination that a reference block for any later sub-PU in an order is coded using motion compensated prediction.

Abstract: Techniques for advanced residual prediction (ARP) for coding video data may include inter-view ARP. Inter-view ARP may include identifying a disparity motion vector (DMV) for a current video block. The DMV is used for inter-view prediction of the current video block based on an inter-view reference video block. The techniques for inter-view ARP may also include identifying temporal reference video blocks in the current and reference views based on a temporal motion vector (TMV) of the inter-view reference video block, and determining a residual predictor block based on a difference between the temporal reference video blocks.

Abstract: A video coder is configured to apply a separable bilinear interpolation filter when determining reference blocks as part of advanced residual prediction. Particularly, the video coder may determine, based on a motion vector of a current block in a current picture of video data, a location of a first reference block in a first reference picture. The video coder may also determine a location of a second reference block in a second reference picture. The video coder may apply a separable bilinear interpolation filter to samples of the second reference picture to determine samples of the second reference block. The video coder may apply the separable bilinear interpolation filter to samples of a third reference picture to determine samples of a third reference block. Each respective sample of a predictive block may be equal to a respective sample of the first reference block plus a respective residual predictor sample.

Abstract: A video encoder generates, based on a reference picture set of a current view component, a reference picture list for the current view component. The reference picture set includes an inter-view reference picture set. The video encoder encodes the current view component based at least in part on one or more reference pictures in the reference picture list. In addition, the video encoder generates a bitstream that includes syntax elements indicating the reference picture set of the current view component. A video decoder parses, from the bitstream, syntax elements indicating the reference picture set of the current view component. The video decoder generates, based on the reference picture set, the reference picture list for the current view component. In addition, the video decoder decodes at least a portion of the current view component based on one or more reference pictures in the reference picture list.

Abstract: A video coder decodes a coding unit (CU) of video data. In decoding the video data, the video coder determines that the CU was encoded using the color space conversion. The video coder determines the initial quantization parameter (QP), determines the final QP that is equal to a sum of the initial QP and a QP offset, and inverse quantizes, based on the final QP, a coefficient block, then reconstructs the CU based on the inverse quantized coefficient blocks.
