摘要： This disclosure describes techniques for intra-prediction mode signaling for video coding. In one example, a video coder is configured to determine, for a block of video data, a set of most probable intra-prediction modes such that the set of most probable intra-prediction modes has a size that is equal to a predetermined number that is greater than or equal to two. The video coder is also configured to code a value representative of an actual intra-prediction mode for the block based at least in part on the set of most probable intra-prediction modes and code the block using the actual intra-prediction mode. The video coder may further be configured to code the block using the actual intra-prediction mode, e.g., to encode or decode the block. Video encoders and video decoders may implement these techniques.

摘要： A video coding device is configured to code coefficients of residual blocks of video data. When a coefficient of a transform unit of video data has a scan order value that is less than a threshold and when the coefficient is the last significant coefficient in a scan order in the transform unit, the video coding device may execute a function to determine a mapping between data for the coefficient and a codeword index value, and code the data for the coefficient using a codeword associated with the codeword index value. The video coding device may comprise a video encoder or a video decoder, in some examples.

摘要： For a block of video data, a video encoder can signal to a video decoder, using a context-based adaptive binary arithmetic coding (CABAC) process, a selected intra-prediction mode using a codeword that is mapped to a modified intra-prediction mode index.

摘要： A video block syntax element indicates whether all of the partitions of a video block are predicted based on a same reference list and no greater than quarter-pixel accuracy is used. If the video block syntax element is set, partition-level signaling of the reference lists is avoided. If the video block syntax element is not set, partition-level signaling of the reference lists occurs. If the video block syntax element is set, partition-level syntax elements may be used for each of the partitions of the video block, wherein the partition-level syntax elements each identify one of the reference lists and motion vector accuracy for a given one of the partitions.
