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： 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 relates to techniques for reducing the amount of additional data encoded with a block encoded using intra-predictive coding. Particularly, the techniques provide apparatus and methods of applying a smoothing filter to prediction samples used in intra-predictive coding. For example, in fixed mode-dependent intra- predictive coding, a video encoder may determine the type of smoothing filter applied to prediction samples based on block size and intra-prediction mode combination associated with the current block, where the combination is used to look up a filter in a first filter table. In adaptive mode-dependent intra-predictive coding, the encoder uses two filters, one from the first filter table and another from a second filter table, applies both filters, and determines which yields better results. When the second filter table filter yields better results, the encoder encodes a filtering indication. When a filter from the first filter table is used, no filtering indication is encoded.

摘要： For each prediction unit (PU) belonging to a coding unit (CU), a video coder generates a candidate list. The video coder generates the candidate list such that each candidate in the candidate list that is generated based on motion information of at least one other PU is generated without using motion information of any of the PUs belonging to the CU. After generating the candidate list for a PU, the video coder generates a predictive video block for the PU based on one or more reference blocks indicated by motion information of the PU. The motion information of the PU is determinable based on motion information indicated by a selected candidate in the candidate list for the PU.
