    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: 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.

    摘要: This disclosure presents methods and systems for coding video in merge mode of a motion vector prediction process. A method of coding video data may determining a merge candidate set for a current prediction unit of a current coding unit, wherein the merge candidate set is determined without comparing motion information of a merge candidate in the merge candidate set to motion information of any other prediction units, and performing a merge motion vector prediction process for the current prediction unit using the merge candidate set. The method may further comprise excluding merge candidates from the merge candidate set that are within another prediction unit of the current coding unit.

    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 coding device may be configured to code a bitstream including multiple views plus depth information. Two of the views may have reduced resolutions, while a third view may have a full resolution. The third view may be predicted relative to upsampled versions of the two reduced-resolution views. Each view may include texture data and depth data, such that a view component may include a texture component and a depth component. Moreover, the texture and depth components may be arranged within an access unit according to a particular order, which may simplify component extraction from the access unit.
