    Abstract: Processing circuitry of a device is configured to determine that a plurality of derived modes (DMs) available for predicting a luma block of video data are also available for predicting a chroma block of the video data, the chroma block corresponding to the luma block, to form a candidate list of prediction modes with respect to the chroma block, the candidate list including one or more DMs of the multiple DMs, to determine to code the chroma block using any DM of the candidate list. The processing circuitry may, based on the determination to code the chroma block using any DM of the one or more DMs of the candidate list, code an indication identifying a selected DM of the candidate list to be used for coding the chroma block. The processing circuitry may code the chroma block according to the selected DM of the candidate list.

    Abstract: Techniques are described for bilateral filtering in video coding process. The techniques utilize non-local bilateral filtering techniques. The non-local bilateral filtering techniques may include determining sample value differences between a first window that includes a current sample to be filtered and one or more additional samples, and a second window that includes a neighboring sample with which the current sample is being filtered and one or more additional samples. The techniques utilize the sample value differences to determine a weighting parameter for bilateral filtering.

    Abstract: A device includes one or more processors configured to derive, from among a plurality of intra prediction modes, M most probable modes (MPMs) for intra prediction of a block of video data. A syntax element indicating whether a MPM index or a non-MPM index is used to indicate a selected intra prediction mode of the plurality of intra prediction modes for intra prediction of the block of video data is decoded. Based on the indicated one of the MPM index or the non-MPM index being the MPM index, the one or more processors select, for each of one or more context-modeled bins of the MPM index, based on intra prediction modes used to decode one or more neighboring blocks, a context index for the context-modeled bin. The one or more processors reconstruct the block of video data based on the selected intra prediction mode.

    Abstract: Techniques are described determining a partition pattern for intra-prediction encoding or decoding a depth block from a partition pattern of one or more partition patterns associated with smaller sized blocks. A video encoder may intra-prediction encode the depth block based on the determined partition pattern, and a video decoder may intra-prediction decode the depth block based on the determine partition pattern.
