摘要： In an example, aspects of this disclosure relate to a method of coding video data that generally includes determining prediction information for a block of video data, where the block is included in a coded unit of video data and positioned below a top row of above-neighboring blocks in the coded unit, and where the prediction information for the block is based on prediction information from one or more other blocks in the coded unit but not based on prediction information from any of the top row of blocks in the coded unit. The method also generally includes coding the block based on the determined prediction information.

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： This disclosure describes video coding techniques applicable to a bi-predictive inter mode that uses adaptive motion vector prediction (AMVP). In particular, this disclosure describes techniques for encoding or decoding video data in which AMVP is used to code a first motion vector and a second motion vector associated with a current video block that is coded in the bi-predictive inter mode. More specifically, this disclosure describes techniques in which one motion vector of a bi-predictive video block can be used to define a candidate motion vector predictor (MVP) for predicting another motion vector of the bi-predictive video block. In many examples, a scaled version of the first motion vector of the bi-predictive video block is used as the MVP for the second motion vector of the bi-predictive video block. By defining an additional MVP candidate for the second motion vector of a bi-predictive video block, improved compression may be achieved.

摘要： A video coder can determine a most probable mode for a block of video data using non-square partitions based on the direction of the non-square partitions. When the direction of the non-square partitions is vertical, an intra prediction mode of a left-neighboring block can be selected as the most probable intra prediction mode, and when the direction of the non-square partitions is horizontal, an intra prediction mode of an above-neighboring block can be selected as the most probable intra prediction mode.
