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： This disclosure describes a bi-predictive merge mode in which a bi-predictive video block inherits motion information from two different neighboring blocks, wherein the two different neighboring blocks were each encoded in a uni-predictive mode. Bi-predictive coding may improve the ability to achieve compression in video coding. The described bi-predictive merge mode may increase the number of bi-predictive candidates that can be used in the context of merge mode coding by allowing two separate uni-predicted neighbors to be used to define bi-predictive motion information for a video block.

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. The video decoder can perform a context-based adaptive binary arithmetic coding (CABAC) process to determine the codeword signaled by the video encoder, determine the modified intra-prediction mode index corresponding to the codeword, determine most probable modes based on a context, map the modified intra-prediction mode index to an intra-prediction mode index by comparing the modified intra-prediction mode index to the mode indexes of the most probable modes, and determine the selected intra-prediction mode used to encode the block of video data based on the intra-prediction mode index.

摘要： Filtering is applied at a video encoder, and filter information is encoded in the bitstream to enable a video decoder to identify the filtering that was applied at the video encoder. The video decoder receives encoded video data that includes the filter information, decodes the video data, and applies filtering based on the filtering information. In this way, the decoder applies the same filtering that was applied at the encoder. Video can be encoded utilizing multiple filters with Laplacian filter indexing for multiple inputs for coded units partitioned using a quadtree partitioning scheme.

摘要： For a first series of video blocks, an encoder determines two filters, a first decoding filter that is to be transmitted to a decoder and a first interim filter that is not to be transmitted to the decoder. The first interim filter is used to determine which coded units of a second series of video blocks are to be filtered. After a decision is made as to which coded units of the second series of video blocks are to be filtered, the encoder determines a second decoding filter for the second series of video blocks and transmits the second decoding filter to the decoder. In addition to determining the second decoding filter, the encoder also determines a second interim filter, which the encoder uses to determine which coded units of a third series of video blocks are to be filtered. This process may repeat for many series of video blocks.

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.
