Abstract: A first reference index value indicates a position, within a reference picture list associated with a current prediction unit (PU) of a current picture, of a first reference picture. A reference index of a co-located PU of a co-located picture indicates a position, within a reference picture list associated with the co-located PU of the co-located picture, of a second reference picture. When the first reference picture and the second reference picture belong to different reference picture types, a video coder sets a reference index of a temporal merging candidate to a second reference index value. The second reference index value is different than the first reference index value.

Abstract: Techniques are described for coding residual data of a prediction residual block with transform skipping. A transform may be skipped for a residual block when the residual block is coded using either a lossless coding mode or a lossy coding mode in a transform skip mode. According to the techniques, based on a transform being skipped for a residual block, a rotation unit included in a video encoder or a video decoder determines whether to rotate the residual block prior to coding residual data of the residual block. In some examples, a rotation value may be explicitly signaled between the video encoder and the video decoder. In other examples, the video encoder and the video decoder may each independently determine whether to rotate the residual block based on a type of boundary at two or more edges of the residual block.

Abstract: In one embodiment, a video coder for coding video data includes a processor and a memory. The processor selects a filter set from a multiple filter sets for upsampling reference layer video data based at least on a prediction operation mode for enhanced layer video data and upsamples the reference layer video data using the selected filter set. Some of the multiple filter sets have some different filter characteristics from one another, and the upsampled reference layer video data has the same spatial resolution as the enhanced layer video data. The processor further codes the enhanced layer video data based at least on the upsampled reference layer video data and the prediction operation mode. The memory stores the upsampled reference layer video data.
