摘要： A unified candidate block set for both adaptive motion vector prediction (AMVP) mode and merge mode for use in inter-prediction is proposed. In general, the same candidate block set is used regardless of which motion vector prediction mode (e.g., merge mode or AMVP mode) is used. In other examples of this disclosure, one candidate block in a set of candidate blocks is designated as an additional candidate block. The additional candidate block is used if one of the other candidate blocks is unavailable. Also, the disclosure proposes a checking pattern where the left candidate block is checked before the below left candidate block. Also, the above candidate block is checked before the right above candidate block.

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 bipredictive intermode 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 bipredictive inter mode. More specifically, this disclosure describes techniques in which one motion vector of a bipredictive video block can be used to define a candidate motion vector predictor (MVP) for predicting another motion vector of the bipredictive video block. In many examples, a scaled version of the first motion vector of the bipredictive video block is used as the MVP for the second motion vector of the bipredictive video block. By defining an additional MVP candidate for the second motion vector of a bipredictive video block, improved compression may be achieved.

摘要： A video encoder may transform residual data by using a transform selected from a group of transforms. The transform is applied to the residual data to create a two-dimensional array of transform coefficients. A scanning mode is selected to scan the transform coefficients in the two-dimensional array into a one-dimensional array of transform coefficients. The combination of transform and scanning mode may be selected from a subset of combinations that is based on an intra-prediction mode. The scanning mode may also be selected based on the transform used to create the two-dimensional array. The transforms and/or scanning modes used may be signaled to a video decoder.
